[libvirt] [PATCH] cpu: Fix definition of flag smap
by Peter Krempa 30 Oct '12

30 Oct '12

A mild case of dyslexia caused that commit 012f9b19ef3812884e207dc431571502de4cebce specifies wrong mask for the smap cpu feature flag. This patch fixes that mistake. --- The flags definition file in qemu can be accessed at: http://git.qemu.org/?p=qemu.git;a=blob;f=target-i386/cpu.c;h=f3708e63b76541… --- src/cpu/cpu_map.xml | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/cpu/cpu_map.xml b/src/cpu/cpu_map.xml index d059e20..f0a1f04 100644 --- a/src/cpu/cpu_map.xml +++ b/src/cpu/cpu_map.xml @@ -270,7 +270,7 @@ <cpuid function='0x00000007' ebx='0x00000080'/> </feature> <feature name='smap'> - <cpuid function='0x00000007' ebx='0x00080000'/> + <cpuid function='0x00000007' ebx='0x00100000'/> </feature>  -- 1.7.12.4

[libvirt] [PATCH 0/2] qemu: Fix <address/> is ignored for USB disks
by Vladislav Bogdanov 30 Oct '12

30 Oct '12

This is a follow-up to https://bugzilla.redhat.com/show_bug.cgi?id=861309 If one has USB disks configured for domain with explicit <address/>, libvirtd ignores that node when building qemu command line. So, disk is connected to the first free USB port implicitly by qemu. That breaks other USB devices which have explicit <address/> - ports they should be connected to may be already occupied by disks. With first patch applied, if one has USB disk connected to the USB hub, qemu fails to start, because it does not know anything about hubs yet (when parsing disks). That's why second patch is needed. Vladislav Bogdanov (2): qemu: Do not ignore address for USB disks qemu: pass -usb and usb hubs earlier, so USB disks with static address are handled properly

[libvirt] [PATCH] build: place attributes in correct location
by Eric Blake 29 Oct '12

29 Oct '12

Ever since commit eefb881, ATTRIBUTE_NONNULL has been a no-op under gcc (since it tends to cause more bugs than it cures given gcc's current lame implementation of the macro). However, the macro is still useful to Coverity and other static-analysis tools, but only if we use it correctly. Gcc (and thus Coverity) accepts function declarations with attributes at the end, but function bodies must attach attributes to the return type. That is, these are valid: void foo(void *arg) ATTRIBUTE_NONNULL(1); void ATTRIBUTE_NONNULL(1) foo(void *arg); void ATTRIBUTE_NONNULL(1) foo(void *arg) {} but this is not: void foo(void *arg) ATTRIBUTE_NONNULL(1) {} Bug introduced in commit 80533ca, with these symptoms: nodeinfo.c:206: error: expected ',' or ';' before '{' token cc1: warning: unrecognized command line option "-Wno-suggest-attribute=const" cc1: warning: unrecognized command line option "-Wno-suggest-attribute=pure" make[3]: *** [libvirt_driver_la-nodeinfo.lo] Error 1 * src/nodeinfo.c (virNodeParseNode): Fix syntax error when non-null attribute is in use. --- Pushing under the build-breaker rule. src/nodeinfo.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/nodeinfo.c b/src/nodeinfo.c index d8b71dd..35c5f96 100644 --- a/src/nodeinfo.c +++ b/src/nodeinfo.c @@ -202,9 +202,9 @@ CPU_COUNT(cpu_set_t *set) /* parses a node entry, returning number of processors in the node and * filling arguments */ static int +ATTRIBUTE_NONNULL(1) ATTRIBUTE_NONNULL(2) +ATTRIBUTE_NONNULL(3) ATTRIBUTE_NONNULL(4) virNodeParseNode(const char *node, int *sockets, int *cores, int *threads) - ATTRIBUTE_NONNULL(1) ATTRIBUTE_NONNULL(2) - ATTRIBUTE_NONNULL(3) ATTRIBUTE_NONNULL(4) { int ret = -1; int processors = 0; -- 1.7.11.7

[libvirt] [PATCHv2] xml: print uuids or shell-escaped names in the warning
by Ján Tomko 29 Oct '12

29 Oct '12

In the XML warning, this prints uuids for domain names with special characters in them and shell-escaped names for other elements (like snapshosts and networks) with special names. --- When saving snapshots, the domain name is appended to the "snapshot-edit" command, so using a domain name that needs escaping would lead to something that can't be just fed to the shell as it would glue them together. diff to xml: shell-escape domain name in comment: - Domain names don't get escaped, UUIDs are preferred. - The command gets escaped too. diff to v1: don't try to use CDATA (it doesn't belong there) --- src/conf/domain_conf.c | 6 +++- src/libvirt_private.syms | 2 + src/qemu/qemu_domain.c | 3 +- src/util/buf.c | 66 ++++++++++++++++++++++++++++++++++++++++++++++ src/util/buf.h | 1 + src/util/xml.c | 62 ++++++++++++++++++++++--------------------- src/util/xml.h | 1 + 7 files changed, 109 insertions(+), 32 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 0933c08..a8cadeb 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -14252,6 +14252,7 @@ int virDomainSaveXML(const char *configDir, virDomainDefPtr def, const char *xml) { + char uuidstr[VIR_UUID_STRING_BUFLEN]; char *configFile = NULL; int ret = -1; @@ -14265,7 +14266,10 @@ int virDomainSaveXML(const char *configDir, goto cleanup; } - ret = virXMLSaveFile(configFile, def->name, "edit", xml); + virUUIDFormat(def->uuid, uuidstr); + ret = virXMLSaveFile(configFile, + virXMLPickShellSafeComment(def->name,uuidstr), "edit", + xml); cleanup: VIR_FREE(configFile); diff --git a/src/libvirt_private.syms b/src/libvirt_private.syms index 699c9a3..b17ef88 100644 --- a/src/libvirt_private.syms +++ b/src/libvirt_private.syms @@ -37,6 +37,7 @@ virBufferError; virBufferEscape; virBufferEscapeSexpr; virBufferEscapeShell; +virBufferEscapeShellXMLComment; virBufferEscapeString; virBufferFreeAndReset; virBufferGetIndent; @@ -1816,6 +1817,7 @@ virURIParse; # xml.h virXMLChildElementCount; virXMLParseHelper; +virXMLPickShellSafeComment; virXMLPropString; virXMLSaveFile; virXPathBoolean; diff --git a/src/qemu/qemu_domain.c b/src/qemu/qemu_domain.c index 4e6a5e9..e4ef7e6 100644 --- a/src/qemu/qemu_domain.c +++ b/src/qemu/qemu_domain.c @@ -1622,7 +1622,8 @@ qemuDomainSnapshotWriteMetadata(virDomainObjPtr vm, goto cleanup; } - if (virAsprintf(&tmp, "snapshot-edit %s", vm->def->name) < 0) { + if (virAsprintf(&tmp, "snapshot-edit %s", + virXMLPickShellSafeComment(vm->def->name, uuidstr)) < 0) { virReportOOMError(); goto cleanup; } diff --git a/src/util/buf.c b/src/util/buf.c index 030dc97..a326465 100644 --- a/src/util/buf.c +++ b/src/util/buf.c @@ -623,6 +623,72 @@ virBufferEscapeShell(virBufferPtr buf, const char *str) } /** + * virBufferEscapeShellXMLComment: + * @buf: the buffer to append to + * @str: an unquoted string + * + * Quotes a string so that the shell (/bin/sh) will interpret the + * quoted string to mean str.

Commit 34e8f63a3 altered virfile.o to drag in additional symbols, which in turn led to pulling in other .o files and eventually causing a link failure when systemtap probes are enabled, such as: ./.libs/libvirt_util.a(libvirt_util_la-event_poll.o): In function `virEventPollRunOnce': /home/dummy/libvirt/src/util/event_poll.c:614: undefined reference to `libvirt_event_poll_run_semaphore' ./.libs/libvirt_util.a(libvirt_util_la-event_poll.o):(.note.stapsdt+0x24): undefined reference to `libvirt_event_poll_add_handle_semaphore' Even though libvirt_iohelper and libvirt_parthelper don't directly use the portion of virfile.o that drags in probing, it was easier to satisfy the linker and get the build back up, than to figure out whether it is even possible or worth trying to disentangle the mess. * src/Makefile.am (libvirt_iohelper_LDADD) (libvirt_parthelper_LDADD): Use libvirt_probes.lo when needed. --- Pushing under the build-breaker rule, in response to: https://www.redhat.com/archives/libvir-list/2012-October/msg01679.html src/Makefile.am | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/src/Makefile.am b/src/Makefile.am index 187663f..1f32263 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -1631,6 +1631,9 @@ libvirt_iohelper_LDFLAGS = $(WARN_LDFLAGS) $(AM_LDFLAGS) libvirt_iohelper_LDADD = \ libvirt_util.la \ ../gnulib/lib/libgnu.la +if WITH_DTRACE_PROBES +libvirt_iohelper_LDADD += libvirt_probes.lo +endif libvirt_iohelper_CFLAGS = $(AM_CFLAGS) endif @@ -1645,6 +1648,9 @@ libvirt_parthelper_LDADD = \ $(LIBPARTED_LIBS) \ libvirt_util.la \ ../gnulib/lib/libgnu.la +if WITH_DTRACE_PROBES +libvirt_parthelper_LDADD += libvirt_probes.lo +endif libvirt_parthelper_CFLAGS = $(LIBPARTED_CFLAGS) $(AM_CFLAGS) endif -- 1.7.11.7

[libvirt] [PATCH] qemu: Report errors from iohelper
by Michal Privoznik 29 Oct '12

29 Oct '12

Currently, we use iohelper when saving/restoring a domain. However, if there's some kind of error (like I/O) it is not propagated to libvirt. Since it is not qemu who is doing the actual write() it will not get error. The iohelper does. Therefore we should check for iohelper errors as it makes libvirt more user friendly. --- diff to v1: -incorporate the event loop to read iohelper's stderr src/libvirt_private.syms | 1 + src/qemu/qemu_driver.c | 7 ++- src/util/virfile.c | 97 ++++++++++++++++++++++++++++++++++++++++++++++ src/util/virfile.h | 2 + 4 files changed, 105 insertions(+), 2 deletions(-) diff --git a/src/libvirt_private.syms b/src/libvirt_private.syms index 699c9a3..68440d0 100644 --- a/src/libvirt_private.syms +++ b/src/libvirt_private.syms @@ -1332,6 +1332,7 @@ virDomainListSnapshots; virFileLoopDeviceAssociate; virFileClose; virFileDirectFdFlag; +virFileWrapperFdCatchError; virFileWrapperFdClose; virFileWrapperFdFree; virFileWrapperFdNew; diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 8af316f..c8e97cf 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -2945,6 +2945,7 @@ endjob: if (rc < 0) VIR_WARN("Unable to resume guest CPUs after save failure"); } + virFileWrapperFdCatchError(wrapperFd); } if (qemuDomainObjEndAsyncJob(driver, vm) == 0) vm = NULL; @@ -3282,9 +3283,11 @@ doCoreDump(struct qemud_driver *driver, cleanup: VIR_FORCE_CLOSE(fd); - virFileWrapperFdFree(wrapperFd); - if (ret != 0) + if (ret != 0) { + virFileWrapperFdCatchError(wrapperFd); unlink(path); + } + virFileWrapperFdFree(wrapperFd); return ret; } diff --git a/src/util/virfile.c b/src/util/virfile.c index 5b00ead..36b3420 100644 --- a/src/util/virfile.c +++ b/src/util/virfile.c @@ -135,10 +135,58 @@ virFileDirectFdFlag(void) * read-write is not supported, just a single direction. */ struct _virFileWrapperFd { virCommandPtr cmd; /* Child iohelper process to do the I/O. */ + int err_fd; /* FD to read stderr of @cmd */ + char *err_msg; /* stderr of @cmd */ + size_t err_msg_len; /* strlen of err_msg so we don't + have to compute it every time */ + int err_watch; /* ID of watch in the event loop */ }; #ifndef WIN32 /** + * virFileWrapperFdReadStdErr: + * @watch: watch ID + * @fd: the read end of pipe to iohelper's stderr + * @events: an OR-ed set of events which occurred on @fd + * @opaque: virFileWrapperFdPtr + * + * This is a callback to our eventloop which will read iohelper's + * stderr, reallocate @opaque->err_msg and copy data. + */ +static void +virFileWrapperFdReadStdErr(int watch ATTRIBUTE_UNUSED, + int fd, int events, void *opaque) +{ + virFileWrapperFdPtr wfd = (virFileWrapperFdPtr) opaque; + char ebuf[1024]; + ssize_t nread; + + if (events & VIR_EVENT_HANDLE_READABLE) { + while ((nread = saferead(fd, ebuf, sizeof(ebuf)))) { + if (nread < 0) { + if (errno != EAGAIN) + virReportSystemError(errno, "%s", + _("unable to read iohelper's stderr")); + break; + } + + if (VIR_REALLOC_N(wfd->err_msg, wfd->err_msg_len + nread + 1) < 0) { + virReportOOMError(); + return; + } + memcpy(wfd->err_msg + wfd->err_msg_len, ebuf, nread); + wfd->err_msg_len += nread; + wfd->err_msg[wfd->err_msg_len] = '\0'; + } + } + + if (events & VIR_EVENT_HANDLE_HANGUP) { + virEventRemoveHandle(watch); + wfd->err_watch = -1; + } +} + +/** * virFileWrapperFdNew: * @fd: pointer to fd to wrap * @name: name of fd, for diagnostics @@ -197,6 +245,8 @@ virFileWrapperFdNew(int *fd, const char *name, unsigned int flags) return NULL; } + ret->err_watch = -1; + mode = fcntl(*fd, F_GETFL); if (mode < 0) { @@ -229,9 +279,36 @@ virFileWrapperFdNew(int *fd, const char *name, unsigned int flags) virCommandAddArg(ret->cmd, "0"); } + /* In order to catch iohelper stderr, we must: + * - pass a FD to virCommand (-1 to auto-allocate one) + * - change iohelper's env so virLog functions print to stderr + */ + ret->err_fd = -1; + virCommandSetErrorFD(ret->cmd, &ret->err_fd); + virCommandAddEnvPair(ret->cmd, "LIBVIRT_LOG_OUTPUTS", "1:stderr"); + if (virCommandRunAsync(ret->cmd, NULL) < 0) goto error; + /* deliberately don't use virCommandNonblockingFDs here as it is all or + * nothing.

The libxl in Xen 4.1 is essentially a one-off and I question whether we should pollute the libvirt libxl driver code with support for a dead, tech preview interface. Xend is still the primary toolstack in Xen 4.1.x, and libvirt has a stable, functional driver for this toolstack that can (should) be used in Xen 4.1.x deployments. Is anyone using the libvirt libxl driver with Xen 4.1 for anything other than development or experimentation? > Another option would be to fork into 4.1 and 4.2+ versions and to stop > adding new stuff to the 4.1 copy. That has its own downsides though. > I'd like to hear what the libvirt community thinks about only supporting Xen >= 4.2 in the libxl driver. Regards, Jim

[libvirt] libxl driver doesn't build with xen 4.2
by Cole Robinson 29 Oct '12

29 Oct '12

Hi Jim, The libvirt libxl driver doesn't build with xen 4.2. There was a small thread about it on fedora's virt list: http://lists.fedoraproject.org/pipermail/virt/2012-October/003446.html I saw that you had a few xen 4.2 patches land recently, and I'm just curious if you were aware of the libxl issues/possibly had any patches brewing. Currently in fedora we've disabled building the libxl driver so the xen guys can pull in their latest bits. Thanks, Cole

You can try a different network config either using the virt-manager GUI tool or by editing the network XML, which is documented here: http://libvirt.org/formatnetwork.html CCed libvirt mailing list.

[libvirt] [PATCH] daemon: Fix LIBVIRT_DEBUG=1 default output

Berrange <berrange(a)redhat.com> Date: Thu Sep 27 13:13:09 2012 +0100 Automatically enable systemd journal logging Probe to see if the systemd journal is accessible, and if so enable logging to the journal by default, rather than stderr (current default under systemd). Previously 'LIBVIRT_DEBUG=1 /usr/sbin/libvirtd' would show all debug output to stderr, now it send debug output to the journal. Only use the journal by default if running in daemon mode, or if stdin is _not_ a tty.

[libvirt] [PATCH] [DRAFT] handle qemu event GUEST_PANICKED
by Hu Tao 29 Oct '12

29 Oct '12

This is for early review, comments are welcome! qemu is adding a method to detect guest panic, and a new event GUEST_PANICKED[1]. This patch adds support for GUEST_PANICKED. But I have two questions: - to react to GUEST_PANICKED, can xml element <on_crash> be used as the action to take, or do I have to invent another xml element to configure the action? - Currently libvirt relies on watchdog to detect guest panic, but this way is not that reliable(there has to be a watchdog device, the watchdog itself has to be working when panic occurs), so it seems to be appropriate to remove this method from libvirt as there is a better one. But, will the removal cause any problems, such as backward compatibility, user confusion, etc.?

[libvirt] [PATCH v3] xml: print uuids in the warning
by Ján Tomko 29 Oct '12

29 Oct '12

In the XML warning, we print a virsh command line that can be used to edit that XML. This patch prints UUIDs if the entity name contains special characters (like shell metacharacters, or "--" that would break parsing of the XML comment). If the entity doesn't have a UUID, just print the virsh command that can be used to edit it. --- As opposed to previous versions, this doesn't use virBuffer and it doesn't do any shell escaping at all. The name parameter can be null now. commit 9b704ab8235af010b1fda4886201aab02098b969 xml: omit domain name from comment if it contains double hyphen only checked the 'name' parameter of virXMLEmitWarning. virXMLSaveFile invocation when creating a snapshot put the domain name in 'cmd', which means that snapshot XMLs of a domain with "--" in the name still can't be parsed by libvirt. --- src/conf/domain_conf.c | 6 +++++- src/conf/network_conf.c | 6 +++++- src/conf/nwfilter_conf.c | 12 ++++++++++-- src/conf/storage_conf.c | 6 +++++- src/libvirt_private.syms | 1 + src/parallels/parallels_storage.c | 3 +-- src/qemu/qemu_domain.c | 9 +-------- src/util/xml.c | 18 +++++++++++++----- src/util/xml.h | 1 + 9 files changed, 42 insertions(+), 20 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 90ec9aa..7bf0282 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -14288,6 +14288,7 @@ int virDomainSaveXML(const char *configDir, virDomainDefPtr def, const char *xml) { + char uuidstr[VIR_UUID_STRING_BUFLEN];

[libvirt] How you can help with maintenance releases
by Cole Robinson 28 Oct '12

28 Oct '12

Hey all, As you're likely aware, I've been cutting maintenance releases of certain libvirt versions for the past six months: http://wiki.libvirt.org/page/Maintenance_Releases Since I'm not hugely involved with development these days, and things move pretty quick in libvirt land, I'd like to appeal to you fine gentleman for a bit of assistance here. None of this is mandatory, but hopefully it's low enough effort that I get a few bites :) Here's the gist: Next time you post a bug fix for an issue you can imagine someone actually hitting and filing a bug report about, consider doing one of the following: - Pushing the patch to the relevant maint branches - CCing me on the posting, with a note that this might be a maint candidate Of course, doing this for patches that someone else posts is completely fine with me too :) Take a look at the current branched versions and their original release dates: libvirt 0.9.6: Sep 22 2011 libvirt 0.9.11: Apr 3 2012 libvirt 0.10.2: September 24 2012 So if you find a bug in code that you know hasn't been touched for a year, it might be a candidate for all 3 branches! Jiri recently noticed this and cherry-picked a patch, (which was very much appreciated!): http://libvirt.org/git/?p=libvirt.git;a=commit;h=bebe5122b9af50f0b25f47f30e… http://libvirt.org/git/?p=libvirt.git;a=commit;h=d325704a3fdf947fa862bf62ec… http://libvirt.org/git/?p=libvirt.git;a=commit;h=77cecd2bc306416d985230bb29… As an example of how to push a patch to a maintenance branch, say you want to backport master commit ab12cd34: git checkout --track remotes/origin/v0.10.2-maint git checkout v0.10.2-maint git cherry-pick -x ab12cd34 git push v0.10.2-maint If the cherry-pick doesn't apply cleanly, feel free to just CC me and I'll straighten it out. That's it! Let me know if you have any questions. Thanks, Cole

[libvirt] [PATCH] qemu: fix attach/detach of netdevs with matching mac addrs
by Laine Stump 27 Oct '12

27 Oct '12

This resolves: https://bugzilla.redhat.com/show_bug.cgi?id=862515 which describes inconsistencies in dealing with duplicate mac addresses on network devices in a domain. (at any rate, it resolves *almost* everything, and prints out an informative error message for the one problem that isn't solved, but has a workaround.) A synopsis of the problems: 1) you can't do a persistent attach-interface of a device with a mac address that matches an existing device. 2) you *can* do a live attach-interface of such a device. 3) you *can* directly edit a domain and put in two devices with matching mac addresses. 4) When running virsh detach-device (live or config), only MAC address is checked when matching the device to remove, so the first device with the desired mac address will be removed. This isn't always the one that's wanted. 5) when running virsh detach-interface (live or config), the only two items that can be specified to match against are mac address and model type (virtio, etc) - if multiple netdevs match both of those attributes, it again just finds the first one added and assumes that is the only match. Since it is completely valid to have multiple network devices with the same MAC address (although it can cause problems in many cases, there *are* valid use cases), what is needed is: 1) remove the restriction that prohibits doing a persistent add of a netdev with a duplicate mac address. 2) enhance the backend of virDomainDetachDeviceFlags to check for something that *is* guaranteed unique (but still work with just mac address, as long as it yields only a single results. This patch does three things: 1) removes the check for duplicate mac address during a persistent netdev attach. 2) unifies the searching for both live and config detach of netdevices in the subordinate functions of qemuDomainModifyDeviceFlags() to use the new function virDomainNetFindIdx (which matches mac address and PCI address if available, checking for duplicates if only mac address was specified). This function returns -2 if multiple matches are found, allowing the callers to print out an appropriate message. Steps 1 & 2 are enough to fully fix the problem when using virsh attach-device and detach-device (which require an XML description of the device rather than a bunch of commandline args) 3) modifies the virsh detach-interface command to check for multiple matches of mac address and show an error message suggesting use of the detach-device command in cases where there are multiple matching mac addresses. Later we should decide how we want to input a PCI address on the virsh commandline, and enhance detach-interface to take a --address option, eliminating the need to use detach-device * src/conf/domain_conf.c * src/conf/domain_conf.h * src/libvirt_private.syms * added new virDomainNetFindIdx function * removed now unused virDomainNetIndexByMac and virDomainNetRemoveByMac * src/qemu/qemu_driver.c * remove check for duplicate max from qemuDomainAttachDeviceConfig * use virDomainNetFindIdx/virDomainNetRemove instead of virDomainNetRemoveByMac in qemuDomainDetachDeviceConfig * use virDomainNetFindIdx instead of virDomainIndexByMac in qemuDomainUpdateDeviceConfig * src/qemu/qemu_hotplug.c * use virDomainNetFindIdx instead of a homespun loop in qemuDomainDetachNetDevice. * tools/virsh-domain.c: modified detach-interface command as described above --- src/conf/domain_conf.c | 58 ++++++++++++++++++++++++++++++++++-------------- src/conf/domain_conf.h | 11 +++------ src/libvirt_private.syms | 3 +-- src/qemu/qemu_driver.c | 49 ++++++++++++++++++++++------------------ src/qemu/qemu_hotplug.c | 28 +++++++++++------------ tools/virsh-domain.c | 26 ++++++++++++++++------ 6 files changed, 104 insertions(+), 71 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 0933c08..51a3b36 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -7993,14 +7993,49 @@ int virDomainNetInsert(virDomainDefPtr def, virDomainNetDefPtr net) return 0;

[libvirt] [PATCHv2] cpustat: fix regression when cpus are offline
by Eric Blake 26 Oct '12

26 Oct '12

It turns out that the cpuacct results properly account for offline cpus, and always returns results for every possible cpu, not just the online ones. So there is no need to check the map of online cpus in the first place, merely only a need to know the maximum possible cpu. Meanwhile, virNodeGetCPUBitmap had a subtle change from returning the maximum id to instead returning the width of the bitmap (one larger than the maximum id) in commit 2f4c5338, which made this code encounter some off-by-one logic leading to bad error messages when a cpu was offline: $ virsh cpu-stats dom error: Failed to virDomainGetCPUStats() error: An error occurred, but the cause is unknown Cleaning this up unraveled a chain of other unused variables. * src/qemu/qemu_driver.c (qemuDomainGetPercpuStats): Drop pointless check for cpumap changes, and use correct number of cpus.

[libvirt] Another curiosity question
by Gene Czarcinski 26 Oct '12

26 Oct '12

All doc and the libvirt software itself is very insistent that dhcp4 will be supported on one and only one IPv4 subnetwork. Why is true? Certainly dnsmasq supports multiple dhcp-range definitions and the actual parameters passed to dnsmasq would be more or less the same! I can understand some restriction if there were systems libvirt suports which does not support the multi-dhcp per interface but not the blanket restriction. This, this is OK: ------------------------------------------------------ <ip address='172.16.6.1' prefix='16'> <dhcp> <range start='172.16.6.128' end='172.16.6.254' /> <range start='172.16.7.128' end='172.16.7.254' /> </dhcp> </ip> ------------------------------------------------------ but this is not: ------------------------------------------------------ <ip address='172.16.6.1' prefix='16'> <dhcp> <range start='172.16.6.128' end='172.16.6.254' /> <range start='172.16.7.128' end='172.16.7.254' /> </dhcp> </ip> <ip address='172.16.7.1' prefix='16'> <dhcp> <range start='172.16.7.128' end='172.16.7.254' /> </dhcp> </ip> ------------------------------------------------------ In both cases, the parameters passed to dnsmasq are: ---------------------------------------------------- dhcp-range=172.16.6.128,172.16.6.254 dhcp-range=172.16.7.128,172.16.7.254 ---------------------------------------------------- and, for dhcp, dnsmasq does not care about the specific addresses since it does its own filtering by listening on 0.0.0.0:67/68 Comments?

[libvirt] [PATCH] cpustat: fix regression when cpus are offline
by Eric Blake 26 Oct '12

26 Oct '12

It turns out that the cpuacct results properly account for offline cpus, and always returns results for every possible cpu, not just the online ones. So there is no need to check the map of online cpus in the first place, merely only a need to know the maximum possible cpu. Meanwhile, virNodeGetCPUBitmap had a subtle change from returning the maximum id to instead returning the width of the bitmap (one larger than the maximum id), which made this code encounter some off-by-one logic leading to bad error messages when a cpu was offline: $ virsh cpu-stats dom error: Failed to virDomainGetCPUStats() error: An error occurred, but the cause is unknown * src/qemu/qemu_driver.c (qemuDomainGetPercpuStats): Drop pointless check for cpumap changes, and use correct number of cpus. --- Fixes the regression noticed here: https://www.redhat.com/archives/libvir-list/2012-October/msg01508.html src/qemu/qemu_driver.c | 26 +++----------------------- 1 file changed, 3 insertions(+), 23 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 18be7d9..f817319 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -13597,7 +13597,6 @@ qemuDomainGetPercpuStats(virDomainPtr domain, unsigned int ncpus) { virBitmapPtr map = NULL; - virBitmapPtr map2 = NULL; int rv = -1; int i, id, max_id; char *pos; @@ -13609,7 +13608,6 @@ qemuDomainGetPercpuStats(virDomainPtr domain, virTypedParameterPtr ent; int param_idx; unsigned long long cpu_time; - bool result; /* return the number of supported params */ if (nparams == 0 && ncpus != 0) @@ -13621,7 +13619,7 @@ qemuDomainGetPercpuStats(virDomainPtr domain, return rv; if (ncpus == 0) { /* returns max cpu ID */ - rv = max_id + 1; + rv = max_id; goto cleanup; } @@ -13648,11 +13646,7 @@ qemuDomainGetPercpuStats(virDomainPtr domain, id = start_cpu + ncpus - 1; for (i = 0; i <= id; i++) { - if (virBitmapGetBit(map, i, &result) < 0) - goto cleanup; - if (!result) { - cpu_time = 0; - } else if (virStrToLong_ull(pos, &pos, 10, &cpu_time) < 0) { + if (virStrToLong_ull(pos, &pos, 10, &cpu_time) < 0) { virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("cpuacct parse error")); goto cleanup; @@ -13680,22 +13674,9 @@ qemuDomainGetPercpuStats(virDomainPtr domain, if (getSumVcpuPercpuStats(group, priv->nvcpupids, sum_cpu_time, n) < 0) goto cleanup; - /* Check that the mapping of online cpus didn't change mid-parse. */ - map2 = nodeGetCPUBitmap(domain->conn, &max_id); - if (!map2 || !virBitmapEqual(map, map2)) { - virReportError(VIR_ERR_OPERATION_INVALID, "%s", - _("the set of online cpus changed while reading")); - goto cleanup; - } - sum_cpu_pos = sum_cpu_time; for (i = 0; i <= id; i++) { - if (virBitmapGetBit(map, i, &result) < 0) - goto cleanup; - if (!result) - cpu_time = 0; - else - cpu_time = *(sum_cpu_pos++); + cpu_time = *(sum_cpu_pos++); if (i < start_cpu) continue; if (virTypedParameterAssign(&params[(i - start_cpu) * nparams + @@ -13711,7 +13692,6 @@ cleanup: VIR_FREE(sum_cpu_time); VIR_FREE(buf); virBitmapFree(map); - virBitmapFree(map2); return rv; } -- 1.7.11.7

[libvirt] how to delete storage-pool entirely
by yue 26 Oct '12

26 Oct '12

it seems that if pools has the same path even with different uuid ,they will be recognize as one pool. if i have defined a pool with a special path, next time to define a new one(same path , different uuid) will fail. then i delete(rm -f ) pool.xml file, define the pool again , it fail too. so if there is cache for all pools been defined until next start libvirtd? my questions: 1. how to delete a pool entilely , include pool-xml file and possible cache (not to restart libvirtd).? 2.throught calling libvirt API , how to find the pool with a special path,no need to define it again? thanks

[libvirt] [PATCH] virsh: Remove --flags from nodesuspend

We always expose individual bits from flags as separate options rather than exposing a raw flags options. Since virNodeSuspendForDuration does not currently support any flags, the only way of using this --flags options that would not fail is "--flags 0", which is equivalent to omitting the option.

[libvirt] [PATCH] network: fix networkValidate check for default portgroup and vlan
by Laine Stump 25 Oct '12

25 Oct '12

This was found during testing of the fix for: https://bugzilla.redhat.com/show_bug.cgi?id=868483 networkValidate was supposed to check for the existence of multiple portgroups and report an error if this was encountered. It did, but there were two problems: 1) even though it logged an error, it still returned success, allowing the operation to continue. 2) It could exit the portgroup checking loop early (or possibly not even do it once) if a vlan tag was supplied in the base network config or one of the portgroups. This patch fixes networkValidate to return failure in addition to logging the error, and also changes it to not exit the portgroup checking loop early. The logic was a bit off in the checking for vlan anyway, and it's intertwined with fixing the early loop exit, so I fixed that as well. Now it correctly checks for combinations where a <virtualport> is specified in the base network def and <vlan> is given in a portgroup, as well as the opposite (<vlan> in base network def and <virtualport> in portgroup), and ignores the case of a disallowed vlan when using *no* portgroup if there is a default portgroup (since in that case there is no way to not use any portgroup). --- src/network/bridge_driver.c | 42 +++++++++++++++++++++++++++++------------- 1 file changed, 29 insertions(+), 13 deletions(-) diff --git a/src/network/bridge_driver.c b/src/network/bridge_driver.c index 8837843..f814f6f 100644 --- a/src/network/bridge_driver.c +++ b/src/network/bridge_driver.c @@ -2617,8 +2617,8 @@ static int networkValidate(virNetworkDefPtr def) { int ii; - bool vlanUsed, vlanAllowed; - const char *defaultPortGroup = NULL; + bool vlanUsed, vlanAllowed, badVlanUse = false; + virPortGroupDefPtr defaultPortGroup = NULL; /* The only type of networks that currently support transparent * vlan configuration are those using hostdev sr-iov devices from @@ -2630,14 +2630,23 @@ networkValidate(virNetworkDefPtr def) def->virtPortProfile->virtPortType == VIR_NETDEV_VPORT_PROFILE_OPENVSWITCH); vlanUsed = def->vlan.nTags > 0; - for (ii = 0; ii < def->nPortGroups && !(vlanUsed && vlanAllowed); ii++) { - if (def->portGroups[ii].vlan.nTags > 0) - vlanUsed = true; - if (def->forwardType == VIR_NETWORK_FORWARD_BRIDGE && - def->portGroups[ii].virtPortProfile && - (def->portGroups[ii].virtPortProfile->virtPortType - == VIR_NETDEV_VPORT_PROFILE_OPENVSWITCH)) { - vlanAllowed = true; + for (ii = 0; ii < def->nPortGroups; ii++) { + if (vlanUsed || def->portGroups[ii].vlan.nTags > 0) { + /* anyone using this portgroup will get a vlan tag.

[libvirt] [PATCH] xml: print uuids or shell-escaped names in the warning
by Ján Tomko 25 Oct '12

In the XML warning, this prints uuids for domain names with special characters in them and shell-escaped names for other elements (like snapshosts and networks) with special names. --- When saving snapshots, the domain name is appended to the "snapshot-edit" command, so using a domain name that needs escaping would lead to something that can't be just fed to the shell. diff to v1: xml: shell-escape domain name in comment The function was changed to shell-escape ']>' instead of '--' as the latter is more likely to happen. Domain names don't get escaped, UUIDs are preferred. --- src/conf/domain_conf.c | 6 +++- src/libvirt_private.syms | 2 + src/qemu/qemu_domain.c | 3 +- src/util/buf.c | 66 ++++++++++++++++++++++++++++++++++++++++++++++ src/util/buf.h | 1 + src/util/xml.c | 61 +++++++++++++++++++++--------------------- src/util/xml.h | 1 + 7 files changed, 108 insertions(+), 32 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 0933c08..342bf2c 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -14252,6 +14252,7 @@ int virDomainSaveXML(const char *configDir, virDomainDefPtr def, const char *xml) { + char uuidstr[VIR_UUID_STRING_BUFLEN]; char *configFile = NULL; int ret = -1; @@ -14265,7 +14266,10 @@ int virDomainSaveXML(const char *configDir, goto cleanup; } - ret = virXMLSaveFile(configFile, def->name, "edit", xml); + virUUIDFormat(def->uuid, uuidstr); + ret = virXMLSaveFile(configFile, + virXMLPickShellSafeCDATA(def->name,uuidstr), "edit", + xml); cleanup: VIR_FREE(configFile); diff --git a/src/libvirt_private.syms b/src/libvirt_private.syms index 699c9a3..4c0b8ca 100644 --- a/src/libvirt_private.syms +++ b/src/libvirt_private.syms @@ -37,6 +37,7 @@ virBufferError; virBufferEscape; virBufferEscapeSexpr; virBufferEscapeShell; +virBufferEscapeShellXMLCDATA; virBufferEscapeString; virBufferFreeAndReset; virBufferGetIndent; @@ -1816,6 +1817,7 @@ virURIParse; # xml.h virXMLChildElementCount; virXMLParseHelper; +virXMLPickShellSafeCDATA; virXMLPropString; virXMLSaveFile; virXPathBoolean; diff --git a/src/qemu/qemu_domain.c b/src/qemu/qemu_domain.c index 4e6a5e9..1522dec 100644 --- a/src/qemu/qemu_domain.c +++ b/src/qemu/qemu_domain.c @@ -1622,7 +1622,8 @@ qemuDomainSnapshotWriteMetadata(virDomainObjPtr vm, goto cleanup; } - if (virAsprintf(&tmp, "snapshot-edit %s", vm->def->name) < 0) { + if (virAsprintf(&tmp, "snapshot-edit %s", + virXMLPickShellSafeCDATA(vm->def->name, uuidstr)) < 0) { virReportOOMError(); goto cleanup; } diff --git a/src/util/buf.c b/src/util/buf.c index 030dc97..7ae52f2 100644 --- a/src/util/buf.c +++ b/src/util/buf.c @@ -623,6 +623,72 @@ virBufferEscapeShell(virBufferPtr buf, const char *str) } /** + * virBufferEscapeShellXMLCDATA: + * @buf: the buffer to append to + * @str: an unquoted string + * + * Quotes a string so that the shell (/bin/sh) will interpret the + * quoted string to mean str.

[libvirt] [PATCHv2 0/9] Resend: New API to retrieve host node CPU map
by Viktor Mihajlovski 24 Oct '12

24 Oct '12

Resending the otherwise unmodified V2 series, as the cover letter didn't show up on the mailing list (at least not in the archive). Sorry for the extra traffic, but I have no clue what went wrong. V2 Changes: Added python binding for virNodeGetCPUMapFlags. Removed RFC stanza. Rationale: In order to use the APIs listed below it is necessary for a client to know the maximum number of node CPUs which is passed via the maplen argument. virDomainGetEmulatorPinInfo virDomainGetVcpuPinInfo virDomainGetVcpus virDomainPinEmulator virDomainPinVcpu virDomainPinVcpuFlags The current approach uses virNodeGetInfo to determine the maximum CPU number. This can lead to incorrect results if not all node CPUs are online. The maximum CPU number should always be the number of CPUs present on the host, regardless of their online/offline state. The following example illustrates the issue: Host has 3 logical CPUs, 1 socket, 3 cores, 1 thread. Guest has 1 virtual CPU and is started while all 3 host CPUs are online. $ virsh vcpuinfo guest VCPU: 0 CPU: 0 State: running CPU time: 35.4s CPU Affinity: yyy $ echo 0 > /sys/devices/system/cpu/cpu1/online $ virsh vcpuinfo guest VCPU: 0 CPU: 0 State: running CPU time: 35.5s CPU Affinity: y- The correct display for CPU affinity would have been y-y, as the guest continues to use CPUs 0 and 2. This is not a display problem only, because it is also not possible to explicitly pin the virtual CPU to host CPUs 0 and 2, due to the truncated CPU mask. PROPOSAL: To help solve the issue above I suggest a new public API: int virNodeGetCPUMapFlags(virConnectPtr conn, unsigned char **cpumap, unsigned int *online, unsigned int flags); The function will return the number of CPUs present on the host or -1 on failure; If cpumap is non-NULL virNodeGetCPUMapFlags will allocate an array containing a bit map representation of the online CPUs. It's the callers responsibility to deallocate cpumap using free(). If online is non-NULL, the variable pointed to will contain the number of online host node CPUs. The variable flags has been added to support future extensions and must be set to 0. Clients can use virNodeGetCPUMapFlags to properly determine the maximum number of node CPUs and their online/offline state. Remarks: This series implements the QEMU and test drivers. This series doesn't introduce changes to the existing vcpu pinning, which I would submit as a succeeding patch set.

[libvirt] [PATCH] cpu: Add recently added cpu feature flags.
by Peter Krempa 24 Oct '12

24 Oct '12

Qemu has added some new feature flags. This patch adds them to libvirt. The new features are for the cpuid function 0x7 that takes an argument in the ecx register. Currently only 0x0 is used as the argument so I was lazy and I just clear the registers to 0 before calling cpuid. In future when there maybe will be some other possible arguments, we will need to improve the cpu detection code to take this into account. --- The qemu flag definiton can be found at: http://git.qemu.org/?p=qemu.git;a=blob;f=target-i386/cpu.c;h=f3708e63b76541… --- src/cpu/cpu_map.xml | 12 ++++++++++++ src/cpu/cpu_x86.c | 8 +++++++- 2 files changed, 19 insertions(+), 1 deletion(-) diff --git a/src/cpu/cpu_map.xml b/src/cpu/cpu_map.xml index affcce3..d059e20 100644 --- a/src/cpu/cpu_map.xml +++ b/src/cpu/cpu_map.xml @@ -142,6 +142,9 @@ <feature name='pdcm'> <cpuid function='0x00000001' ecx='0x00008000'/> </feature> + <feature name='pcid'> + <cpuid function='0x00000001' ecx='0x00020000'/> + </feature> <feature name='dca'>  <cpuid function='0x00000001' ecx='0x00040000'/> </feature> @@ -261,6 +264,15 @@ <cpuid function='0x80000001' ecx='0x00080000'/> </feature> +  +  + <feature name='smep'> + <cpuid function='0x00000007' ebx='0x00000080'/> + </feature> + <feature name='smap'> + <cpuid function='0x00000007' ebx='0x00080000'/> + </feature> +  <model name='486'> <feature name='fpu'/> diff --git a/src/cpu/cpu_x86.c b/src/cpu/cpu_x86.c index 7cd67b8..f54c3df 100644 --- a/src/cpu/cpu_x86.c +++ b/src/cpu/cpu_x86.c @@ -1539,7 +1539,10 @@ static inline void cpuidCall(struct cpuX86cpuid *cpuid) { # if __x86_64__ - asm("cpuid" + asm("xor %%ebx, %%ebx;" /* clear the other registers as some cpuid */ + "xor %%ecx, %%ecx;" /* functions may use them as additional */ + "xor %%edx, %%edx;" /* arguments */ + "cpuid" : "=a" (cpuid->eax), "=b" (cpuid->ebx), "=c" (cpuid->ecx), @@ -1550,6 +1553,9 @@ cpuidCall(struct cpuX86cpuid *cpuid) * for global offset table on i386 with -fPIC */ asm("push %%ebx;" + "xor %%ebx, %%ebx;" /* clear the other registers as some cpuid */ + "xor %%ecx, %%ecx;" /* functions may use them as additional */ + "xor %%edx, %%edx;" /* arguments */ "cpuid;" "mov %%ebx, %1;" "pop %%ebx;" -- 1.7.12.4

[libvirt] [PATCH] selinux: Don't fail RestoreAll if file doesn't have a default label
by Cole Robinson 24 Oct '12

24 Oct '12

When restoring selinux labels after a VM is stopped, any non-standard path that doesn't have a default selinux label causes the process to stop and exit early. This isn't really an error condition IMO. Of course the selinux API could be erroring for some other reason but hopefully that's rare enough to not need explicit handling.

[libvirt] [PATCHv2 00/11] util: add VIR_(INSERT|DELETE)_ELEMENTS_N
by Laine Stump 24 Oct '12

24 Oct '12

This is a repost of https://www.redhat.com/archives/libvir-list/2012-October/msg01080.html with PATCH 03/12 squashed into 01/12. There are no other changes. ************************************ PATCH 01/11 defines a couple new macros/functions to simplify inserting/deleting items in the middle of an array. The remaining patches switch over various pieces of existing code to use these new macros rather than directly calling memmove, etc. There are several other places where these macros could *almost* be used, except that they use the model of pre-allocating the larger array, then performing a bunch of operations (that may fail) and then finally move items around in the array and adjust its count. I'm wondering if I should add a flags arg to these to allow for specifying a "Don't realloc" flag - when it was given, the memory allocation operation would be presumed already done (in the case of insert) or to be done after return (for delete). Any opinions on that? (such as maybe "that's too many options!")

[libvirt] [PATCH] Refactor ESX storage driver and add iSCSI support
by Ata E Husain Bohra 23 Oct '12

23 Oct '12

The patch refactors the current ESX storage driver due to following reasons: 1. Given most of the public APIs exposed by the storage driver in Libvirt remains same, ESX storage driver should not implement logic specific for only one supported format (current implementation only supports VMFS). 2. Decoupling interface from specific storage implementation gives us an extensible design to hook implementation for other supported storage formats. This patch refactors the current driver to implement it as a facade pattern i.e. the driver exposes all the public libvirt APIs, but uses backend drivers to get the required task done. The backend drivers provide implementation specific to the type of storage device. File changes: ------------------ esx_storage_driver.c ----> esx_storage_driver.c (base storage driver) | |---> esx_storage_backend_vmfs.c (VMFS backend) | |---> esx_storage_backend_iscsi.c (iSCSI backend) The patch adds the backend driver to support iSCSI format storage pools and volumes for ESX host. The mapping of ESX iSCSI specifics to Libvirt is as follows: 1. ESX static iSCSI target <------> Libvirt Storage Pools 2. ESX iSCSI LUNs <------> Libvirt Storage Volumes. The above understanding is based on http://libvirt.org/storage.html. The operation supported on iSCSI pools includes: 1. List storage pools & volumes. 2. Get xml descriptor operaion on pools & volumes. 3. Lookup operation on pools & volumes by name, uuid and path (if applicable). iSCSI pools does not support operations such as: Create / remove pools and volumes --- src/Makefile.am | 16 +- src/esx/esx_driver.c | 4 +- src/esx/esx_storage_backend_iscsi.c | 794 +++++++++++++++++++ src/esx/esx_storage_backend_iscsi.h | 31 + src/esx/esx_storage_backend_vmfs.c | 1471 +++++++++++++++++++++++++++++++++++ src/esx/esx_storage_backend_vmfs.h | 31 + src/esx/esx_storage_driver.c | 1303 +++++-------------------------- src/esx/esx_vi.c | 341 +++++++- src/esx/esx_vi.h | 21 +- src/esx/esx_vi_generator.input | 308 +++++++- src/esx/esx_vi_generator.py | 19 + 11 files changed, 3218 insertions(+), 1121 deletions(-) create mode 100644 src/esx/esx_storage_backend_iscsi.c create mode 100644 src/esx/esx_storage_backend_iscsi.h create mode 100644 src/esx/esx_storage_backend_vmfs.c create mode 100644 src/esx/esx_storage_backend_vmfs.h diff --git a/src/Makefile.am b/src/Makefile.am index d35edd6..8f58a8a 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -475,13 +475,15 @@ UML_DRIVER_SOURCES = \ uml/uml_conf.c uml/uml_conf.h \ uml/uml_driver.c uml/uml_driver.h -ESX_DRIVER_SOURCES = \ - esx/esx_private.h \ - esx/esx_driver.c esx/esx_driver.h \ - esx/esx_interface_driver.c esx/esx_interface_driver.h \ - esx/esx_network_driver.c esx/esx_network_driver.h \ - esx/esx_storage_driver.c esx/esx_storage_driver.h \ - esx/esx_device_monitor.c esx/esx_device_monitor.h \ +ESX_DRIVER_SOURCES = \ + esx/esx_private.h \ + esx/esx_driver.c esx/esx_driver.h \ + esx/esx_interface_driver.c esx/esx_interface_driver.h \ + esx/esx_network_driver.c esx/esx_network_driver.h \ + esx/esx_storage_driver.c esx/esx_storage_driver.h \ + esx/esx_storage_backend_vmfs.c esx/esx_storage_backend_vmfs.h \ + esx/esx_storage_backend_iscsi.c esx/esx_storage_backend_iscsi.h \ + esx/esx_device_monitor.c esx/esx_device_monitor.h \ esx/esx_secret_driver.c esx/esx_secret_driver.h \ esx/esx_nwfilter_driver.c esx/esx_nwfilter_driver.h \ esx/esx_util.c esx/esx_util.h \ diff --git a/src/esx/esx_driver.c b/src/esx/esx_driver.c index 72a7acc..359de53 100644 --- a/src/esx/esx_driver.c +++ b/src/esx/esx_driver.c @@ -162,7 +162,7 @@ esxParseVMXFileName(const char *fileName, void *opaque) datastoreName = NULL; if (esxVI_LookupDatastoreHostMount(data->ctx, datastore->obj, - &hostMount) < 0 || + &hostMount, esxVI_Occurrence_RequiredItem) < 0 || esxVI_GetStringValue(datastore, "summary.name", &datastoreName, esxVI_Occurrence_RequiredItem) < 0) { goto cleanup; @@ -306,7 +306,7 @@ esxFormatVMXFileName(const char *fileName, void *opaque) if (esxVI_LookupDatastoreByName(data->ctx, datastoreName, NULL, &datastore, esxVI_Occurrence_RequiredItem) < 0 || esxVI_LookupDatastoreHostMount(data->ctx, datastore->obj, - &hostMount) < 0) { + &hostMount, esxVI_Occurrence_RequiredItem) < 0) { goto cleanup; } diff --git a/src/esx/esx_storage_backend_iscsi.c b/src/esx/esx_storage_backend_iscsi.c new file mode 100644 index 0000000..4f79a0f --- /dev/null +++ b/src/esx/esx_storage_backend_iscsi.c @@ -0,0 +1,794 @@ +/* + * esx_storage_backend_iscsi.c: ESX storage backend for iSCSI handling + * + * Copyright (C) 2007-2008, 2010-2012 Red Hat, Inc. + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; either + * version 2.1 of the License, or (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

[libvirt] [PATCHv5 0/3] Transport Open vSwitch per-port data during live migration
by Laine Stump 23 Oct '12

23 Oct '12

In-Reply-To: This is an update (of an update :-) of Kyle Mestery's patch series v3 by the same name: https://www.redhat.com/archives/libvir-list/2012-October/msg00014.html I've updated it according to the comments in the review of patch 1/3 of that series: https://www.redhat.com/archives/libvir-list/2012-October/msg01224.html and also according to Michal and Eric's comments on v4: https://www.redhat.com/archives/libvir-list/2012-October/msg01227.html (interdiffs for those last changes are attached to patches 1/3 and 2/3) It now needs a counter-review from Kyle, along with verification that it actually works (since I don't have the proper setup to test it handy). ****************************************** This series of commits has the end goal of allowing per-port data stored in the Open vSwitch DB to be transported during live migration.

[libvirt] [PATCH 00/12] util: add VIR_(INSERT|DELETE)_ELEMENTS_N
by Laine Stump 23 Oct '12

23 Oct '12

PATCH 01/12 defines a couple new macros/functions to simplify inserting/deleting items in the middle of an array. The remaining patches switch over various pieces of existing code to use these new macros rather than directly calling memmove, etc. There are several other places where these macros could *almost* be used, except that they use the model of pre-allocating the larger array, then performing a bunch of operations (that may fail) and then finally move items around in the array and adjust its count. I'm wondering if I should add a flags arg to these to allow for specifying a "Don't realloc" flag - when it was given, the memory allocation operation would be presumed already done (in the case of insert) or to be done after return (for delete). Any opinions on that?

[libvirt] [PATCH] xml: omit domain name from comment if it contains double hyphen
by Ján Tomko 23 Oct '12

23 Oct '12

[libvirt] Add device operations support for libvirt (lxc)
by Heiher 23 Oct '12

23 Oct '12

Hello, Currently, libvirt is not support device operations for lxc. This is a patch that add device operations support for libvirt 0.10.2. 1. lxcDomainAttachDevice 2. lxcDomainAttachDeviceFlags 3. lxcDomainDetachDevice 4. lxcDomainDetachDeviceFlags 5. lxcDomainUpdateDeviceFlags In live mode, set devices.allow/deny to instance's cgroup and insert disk config into current domain. In config mode, just insert disk config into current domain. This is part of 'Fix up attach/detach volume for nova (openstack)'. Please see: https://bugzilla.redhat.com/show_bug.cgi?id=869259 -- Best regards! Heiher https://heiher.info

[libvirt] RFC: advertising graphics support (vnc, spice, sdl)
by Doug Goldstein 23 Oct '12

23 Oct '12

Currently consumers of libvirt's APIs must assume/attempt to define a VM that uses spice, vnc, or sdl without knowing if the actual hypervisor supports it. Obviously my discussion is very QEMU oriented but it would be good to leave expansion for the future. I was thinking that under the <guest> element for the capabilities we can add something like: <graphics> <spice/> <vnc/> <sdl/> </graphics> It would be at the same level as <arch> and <features>. But before I implemented this I wanted a sanity check if people think this is the best place or the best naming convention. Thanks. -- Doug Goldstein

[libvirt] [PATCH] qemu: Report errors from iohelper
by Michal Privoznik 23 Oct '12

23 Oct '12

Currently, we use iohelper when saving/restoring a domain. However, if there's some kind of error (like I/O) it is not propagated to libvirt. Since it is not qemu who is doing the actual write() it will not get error. The iohelper does. Therefore we should check for iohelper errors as it makes libvirt more user friendly. --- src/libvirt_private.syms | 1 + src/qemu/qemu_driver.c | 7 ++++- src/util/virfile.c | 47 ++++++++++++++++++++++++++++++++++++++++++++++ src/util/virfile.h | 2 + 4 files changed, 55 insertions(+), 2 deletions(-) diff --git a/src/libvirt_private.syms b/src/libvirt_private.syms index 60f9c7f..26eb7b1 100644 --- a/src/libvirt_private.syms +++ b/src/libvirt_private.syms @@ -1332,6 +1332,7 @@ virDomainListSnapshots; virFileLoopDeviceAssociate; virFileClose; virFileDirectFdFlag; +virFileWrapperFdCatchError; virFileWrapperFdClose; virFileWrapperFdFree; virFileWrapperFdNew; diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 8af316f..c8e97cf 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -2945,6 +2945,7 @@ endjob: if (rc < 0) VIR_WARN("Unable to resume guest CPUs after save failure"); } + virFileWrapperFdCatchError(wrapperFd); } if (qemuDomainObjEndAsyncJob(driver, vm) == 0) vm = NULL; @@ -3282,9 +3283,11 @@ doCoreDump(struct qemud_driver *driver, cleanup: VIR_FORCE_CLOSE(fd); - virFileWrapperFdFree(wrapperFd); - if (ret != 0) + if (ret != 0) { + virFileWrapperFdCatchError(wrapperFd); unlink(path); + } + virFileWrapperFdFree(wrapperFd); return ret; } diff --git a/src/util/virfile.c b/src/util/virfile.c index 5b00ead..4d7538e 100644 --- a/src/util/virfile.c +++ b/src/util/virfile.c @@ -135,6 +135,7 @@ virFileDirectFdFlag(void) * read-write is not supported, just a single direction. */ struct _virFileWrapperFd { virCommandPtr cmd; /* Child iohelper process to do the I/O. */ + int err_fd; /* FD to read stderr of @cmd */ }; #ifndef WIN32 @@ -229,6 +230,14 @@ virFileWrapperFdNew(int *fd, const char *name, unsigned int flags) virCommandAddArg(ret->cmd, "0"); } + /* In order to catch iohelper stderr, we must: + * - pass a FD to virCommand (-1 to auto-allocate one) + * - change iohelper's env so virLog functions print to stderr + */ + ret->err_fd = -1; + virCommandSetErrorFD(ret->cmd, &ret->err_fd); + virCommandAddEnvPair(ret->cmd, "LIBVIRT_LOG_OUTPUTS", "1:stderr"); + if (virCommandRunAsync(ret->cmd, NULL) < 0) goto error; @@ -280,6 +289,42 @@ virFileWrapperFdClose(virFileWrapperFdPtr wfd) return virCommandWait(wfd->cmd, NULL); } + +/** + * virFileWrapperFdCatchError: + * @wfd: fd wrapper, or NULL + * + * Read the stderr of iohelper and VIR_WARN() about it. + */ +void +virFileWrapperFdCatchError(virFileWrapperFdPtr wfd) +{ + char *err = NULL; + char ebuf[1024]; + size_t nread = 0; + size_t err_size = 0; + + if (!wfd) + return; + + while ((nread = saferead(wfd->err_fd, ebuf, sizeof(ebuf)))) { + if (VIR_REALLOC_N(err, err_size + nread + 1) < 0) { + virReportOOMError(); + goto cleanup; + } + memcpy(err + err_size, ebuf, nread); + err_size += nread; + err[err_size] = '\0'; + } + + if (err) + VIR_WARN("iohelper reports: %s", err); + +cleanup: + VIR_FREE(err); +} + + /** * virFileWrapperFdFree: * @wfd: fd wrapper, or NULL @@ -295,6 +340,8 @@ virFileWrapperFdFree(virFileWrapperFdPtr wfd) if (!wfd) return; + VIR_FORCE_CLOSE(wfd->err_fd); + virCommandFree(wfd->cmd); VIR_FREE(wfd); } diff --git a/src/util/virfile.h b/src/util/virfile.h index c885b73..80daf86 100644 --- a/src/util/virfile.h +++ b/src/util/virfile.h @@ -90,6 +90,8 @@ int virFileWrapperFdClose(virFileWrapperFdPtr dfd); void virFileWrapperFdFree(virFileWrapperFdPtr dfd); +void virFileWrapperFdCatchError(virFileWrapperFdPtr dfd); + int virFileLock(int fd, bool shared, off_t start, off_t len); int virFileUnlock(int fd, off_t start, off_t len); -- 1.7.8.6

[libvirt] [PATCH v2] put dnsmasq parameters into a file instead of the command line

23 Oct '12

This patch changes the way parameters are passed to dnsmasq. They are put into a conf-file instead of being on the dnsmasq command line. **NOTE ** This has updated the related tests for the new data format, etc. **NOTE** This patch does NOT include specifying interface= The command line now contains --conf-file=<filename> and a new parameter --conf-dir=<directoryname> has been added.

[libvirt] Need new maintainer for libvirt on MacPorts
by Justin Clift 23 Oct '12

23 Oct '12

Hi all, Is anyone up for being the new owner/maintainer for libvirt on OSX MacPorts? The MacPorts guys have pinged us, suggesting we update the libvirt port there to something recent: https://trac.macports.org/ticket/36691 I'm still very engaged on the Homebrew side, but have next to no interest in MacPorts so am looking to pass it on. :) ? Regards and best wishes, Justin Clift -- Aeolus Community Manager http://www.aeolusproject.org

[libvirt] patch option needs clarification
by Gene Czarcinski 23 Oct '12

23 Oct '12

I am pretty much complete creating a patch which changes how dnsmasq is started by moving the command line parameters into a conf file. This new file is placed into the same directory and the lease file. The test for the command line arguments now checks the contents of the conf-file and there is no longer any tests for the command line parameters which are now two. The first command line parameter is (naturally) --conf-file=<filename>. The second parameter adds new functionality and is --conf-dir=<directory>. This directory is placed into the same directory as the conf-file and the lease file. The name of this directory is "<net-name>.d". This was added to make testing/debugging of new dnsmasq options easier since it no longer requires rebuilding the binaries. This is also useful for adding log-dhcp and/or log-queries for a specific network. Now the option question. I can submit the patch assuming the my previously submitted patch to add --interface to the command line has been applied or I can assume that it has not been applied. In either case, the new code adds a interface=<dev-name> to the conf-file. All development and testing was done with 0.10.2 libvirt src.rpm on Fedora 17. The patch will be submitted based on git.

[libvirt] [PATCHv2] Fix disabling of apparmor/selinux security drivers
by Christophe Fergeau 23 Oct '12

23 Oct '12

When using --without-$name --without-secdriver-$name with $name being selinux or apparmor, configure will fail saying that AppArmor/SELinux development package must be installed. This is caused by a small bug in --with-secdriver-$name handling in configure.ac which treats --without-secdriver-$name when $name as if the user had requested to enable $name when $name couldn't be detected on the system. This commit also makes sure the detection checks for disabled secdrivers do not needlessly get run, especially as this could cause an error as well in --with-$name --without-secdriver-$name situations. --- configure.ac | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) diff --git a/configure.ac b/configure.ac index 8810efd..5ea3bc2 100644 --- a/configure.ac +++ b/configure.ac @@ -1493,10 +1493,11 @@ AC_ARG_WITH([secdriver-selinux], if test "$with_selinux" != "yes" ; then if test "$with_secdriver_selinux" = "check" ; then with_secdriver_selinux=no - elif test "$with_secdriver_selinux" = "yes"; then + fi + if test "$with_secdriver_selinux" != "no"; then AC_MSG_ERROR([You must install the libselinux development package and enable SELinux with the --with-selinux=yes in order to compile libvirt --with-secdriver-selinux=yes]) fi -else +elif test "$with_secdriver_selinux" != "no"; then old_cflags="$CFLAGS" old_libs="$LIBS" CFLAGS="$CFLAGS $SELINUX_CFLAGS" @@ -1571,10 +1572,11 @@ AC_ARG_WITH([secdriver-apparmor], if test "$with_apparmor" != "yes" ; then if test "$with_secdriver_apparmor" = "check" ; then with_secdriver_apparmor=no - else + fi + if test "$with_secdriver_apparmor" != "no" ; then AC_MSG_ERROR([You must install the AppArmor development package in order to compile libvirt]) fi -else +elif test "with_secdriver_apparmor" != "no" ; then old_cflags="$CFLAGS" old_libs="$LIBS" CFLAGS="$CFLAGS $APPARMOR_CFLAGS" -- 1.7.12.1

Version-Release number of selected component (if applicable): libvirt-0.9.0 How reproducible: when i am giving the following command for virsh: virsh -connect vbox:///session then the following error is coming. error: no hypervisor driver available for vbox:///session error: failed to connect to the hypervisor Even I installed virtualbox the above error is coming. I am not able to find vbox hypervisor driver. Can anyone suggest where can i find vbox dirver.

[libvirt] vbox Hypervisor driver not found
by p.venkatasrinivas＠tcs.com 23 Oct '12

23 Oct '12

Hi, I installed Libvirt. We need virtualbox support for libvirt. But we are unable to see the vbox option in virt-manager. How we can find vbox hypervisor driver? And also we already compiled libvirt with vbox option.(--with-vbox). But that didn't work. And also when we are creating the new virtual machine through virt-manager we are getting the following error: internal error cannot parse QEMU version number in "" Can you please suggest on this what we need to do as soon as possible? Thanks in advance.

[libvirt] [PATCH v1] helper of copy-storage-* features
by liguang 23 Oct '12

help to create disk images copy-storage-* required, try to do non-shared migration without bothering to create disk images at target by hand. consider this situation: 1. non-shared migration virsh migrate --copy-storage-all ... 2. migration fails 3. create disk images required qemu-img create ... 4 migration run smoothly so, try do remove step 2, 3, 4 this kind of usage had been discussed before, http://www.redhat.com/archives/libvir-list/2011-December/msg00451.html maybe there're some flaws: - It did not handle more about complete situations suggested by Daniel P. Berrange, https://www.redhat.com/archives/libvir-list/2012-October/msg00407.html but may try to take care of them later. so, now only normal disk image files be handled. - for creation of disk images, size was setting as 0xffffffff boldly, hope it can consolidate qemu, haven't constructed a comfortable idea to solve it.

[libvirt] [PATCH 0/3] Transport Open vSwitch per-port data during live migration
by Kyle Mestery 22 Oct '12

22 Oct '12

This series of commits has the end goal of allowing per-port data stored in the Open vSwitch DB to be transported during live migration. This is done by first providing a generic infrastructure for transporting network data, adding some utility functions specific to Open vSwitch, and hooking the two together. The framework provided is generic in that other networking data could be transferred as well by simply adding in additional hooks as needed. Kyle Mestery (3): Add the ability for the Qemu V3 migration protocol to include transporting network configuration. A generic framework is proposed with this patch to allow for the transfer of opaque data. Add utility functions for Open vSwitch to both save per-port data before a live migration, and restore the per-port data after a live migration. Transport Open vSwitch per-port data during live migration by using the utility functions virNetDevOpenvswitchGetMigrateData() and virNetDevOpenvswitchSetMigrateData(). src/libvirt_private.syms | 2 + src/qemu/qemu_migration.c | 263 +++++++++++++++++++++++++++++++++++++++- src/util/virnetdevopenvswitch.c | 70 +++++++++++ src/util/virnetdevopenvswitch.h | 6 + 4 files changed, 339 insertions(+), 2 deletions(-) -- 1.7.11.4

[libvirt] [PATCH] storage: Don't do wait loops from VolLookupByPath
by Cole Robinson 22 Oct '12

22 Oct '12

virStorageVolLookupByPath is an API call that virt-manager uses quite a bit when dealing with storage. This call use BackendStablePath which has several usleep() heuristics that can be tripped up and hang virt-manager for a while. Current example: an empty mpath pool pointing to /dev/mapper makes _any_ calls to virStorageVolLookupByPath take 5 seconds. The sleep heuristics are actually only needed in certain cases when we are waiting for new storage to appear, so let's skip the timeout steps when calling from LookupByPath. --- src/storage/storage_backend.c | 12 ++++++++---- src/storage/storage_backend.h | 3 ++- src/storage/storage_backend_disk.c | 2 +- src/storage/storage_backend_scsi.c | 3 ++- src/storage/storage_driver.c | 3 ++- 5 files changed, 15 insertions(+), 8 deletions(-) diff --git a/src/storage/storage_backend.c b/src/storage/storage_backend.c index aea70e2..85b8287 100644 --- a/src/storage/storage_backend.c +++ b/src/storage/storage_backend.c @@ -1338,10 +1338,14 @@ virStorageBackendDetectBlockVolFormatFD(virStorageVolTargetPtr target, * * Typically target.path is one of the /dev/disk/by-XXX dirs * with stable paths. + * + * If 'wait' is true, we use a timeout loop to give dynamic paths + * a change to appear. */ char * virStorageBackendStablePath(virStoragePoolObjPtr pool, - const char *devpath) + const char *devpath, + bool wait) { DIR *dh; struct dirent *dent; @@ -1372,7 +1376,7 @@ virStorageBackendStablePath(virStoragePoolObjPtr pool, reopen: if ((dh = opendir(pool->def->target.path)) == NULL) { opentries++; - if (errno == ENOENT && opentries < 50) { + if (wait && errno == ENOENT && opentries < 50) { usleep(100 * 1000); goto reopen; } @@ -1387,7 +1391,7 @@ virStorageBackendStablePath(virStoragePoolObjPtr pool, * the target directory and figure out which one points * to this device node. * - * And it might need some time till the stabe path shows + * And it might need some time till the stable path shows * up, so add timeout to retry here. */ retry: @@ -1411,7 +1415,7 @@ virStorageBackendStablePath(virStoragePoolObjPtr pool, VIR_FREE(stablepath); } - if (++retry < 100) { + if (wait && ++retry < 100) { usleep(100 * 1000); goto retry; } diff --git a/src/storage/storage_backend.h b/src/storage/storage_backend.h index a67eeb7..71935a7 100644 --- a/src/storage/storage_backend.h +++ b/src/storage/storage_backend.h @@ -130,7 +130,8 @@ virStorageBackendDetectBlockVolFormatFD(virStorageVolTargetPtr target, int fd); char *virStorageBackendStablePath(virStoragePoolObjPtr pool, - const char *devpath); + const char *devpath, + bool wait); typedef int (*virStorageBackendListVolRegexFunc)(virStoragePoolObjPtr pool, char **const groups, diff --git a/src/storage/storage_backend_disk.c b/src/storage/storage_backend_disk.c index 5d9e72f..3cd4362 100644 --- a/src/storage/storage_backend_disk.c +++ b/src/storage/storage_backend_disk.c @@ -83,7 +83,7 @@ virStorageBackendDiskMakeDataVol(virStoragePoolObjPtr pool, * dir every time its run.

[libvirt] [PATCHv8 00/11] blockjob: storage migration via block-copy
by Eric Blake 22 Oct '12

22 Oct '12

v7 of these patches is here: https://www.redhat.com/archives/libvir-list/2012-September/msg01122.html Since then, I have rebased the series on top of my block-commit work, which changed (and simplified) several patches. Also, upstream qemu is closer to taking Paolo's patches that actually add the 'drive-mirror' monitor command, although it still isn't official there; so I'm still a bit reluctant to push patches 3-11 into libvirt.git until qemu.git actually gains support for block copy. Patches 1 and 2 are new, and can be applied now if they get a good review. I've done some light testing with the qemu-kvm-rhev of RHEV 3.0, so I'm fairly confident that my rebase work is correct.

[libvirt] how libvirt communicate with qemu?
by yue 22 Oct '12

22 Oct '12

i am reading source code, begin with tracing simple command line ,like virsh list and forth. please look at my qurestions 1.how libvirt communicate with qemu? call qemu'lib or open special device/socket? 2. i do not find the implement of function qemuAgentOpen---->qemuAgentInitialize(). i also search qemu-kvm source 3. qemuListAllDomains is the function which corespond to virsh-list. please explain this function . virDomainList(conn, driver->domains.objs, domains, flags); i) it seems driver->domains.objs have gotten all dmains. so when and where driver->domains.objs is assigned. ii)and what is conn,and its definition? thanks.
