[libvirt] [PATCHv2 0/3] openvz: allow for runtime quota updates
by Guido Günther 12 Jun '12

12 Jun '12

Hi, attached patches allow to change disk quota at runtime. This can later be extended to update network configuration as well. The patch revealed a problem of the openvz driver in genral: the openvzLoadDomains only reads the on disk configuration but doesn't check if running domains have (non persistent) diverging values due to openvz calls without the "--save" option but that's part of another patch. Changes since last time: * add virDomainFSIndexByName to libvirt_private.syms * check for unallowed updates in openvzUpdateDevice Cheers, -- Guido Guido Günther (3): Introduce virDomainFSIndexByName openvz: add persist parameter to openvzSetDiskQuota openvz: wire up domainUpdateDeviceFlags src/conf/domain_conf.c | 16 ++++++ src/conf/domain_conf.h | 1 + src/libvirt_private.syms | 1 + src/openvz/openvz_driver.c | 116 ++++++++++++++++++++++++++++++++++++++++++-- 4 files changed, 130 insertions(+), 4 deletions(-) -- 1.7.10.4

[libvirt] [libvirt-sandbox][PATCH] module lookup and rundir fix
by Radu C. 12 Jun '12

12 Jun '12

Hello, I've been trying to get libvirt-sandbox working on my Gentoo box but I ran into some difficulties. The version I'm using is the latest git one. The first problem was the following when running virt-sandbox: "Unable to start sandbox: Error opening file '/tmp/libvirt-sandbox-9ivpRN/9pnet.ko': File exists" I pinpointed the problem to the following diff in commit [05fb94d2c42abe9cfd86c3663d704c268f325503]: - gchar *moddirpath = g_strdup_printf("/lib/modules/%s/kernel", + gchar *moddirpath = g_strdup_printf("/lib/modules/%s", The problem is that symlinks are made to the build directory and it finds a module multiple times. I inserted a printf in the lookup loop so here's what I mean: dmns libvirt-sandbox # virt-sandbox -c qemu:///system -n test1323 -v -d /usr/bin/yes found: /lib/modules/3.4.0-gentoo/kernel/fs/fscache/fscache.ko found: /lib/modules/3.4.0-gentoo/source/fs/fscache/fscache.ko found: /lib/modules/3.4.0-gentoo/build/fs/fscache/fscache.ko found: /lib/modules/3.4.0-gentoo/kernel/net/9p/9pnet.ko found: /lib/modules/3.4.0-gentoo/source/net/9p/9pnet.ko found: /lib/modules/3.4.0-gentoo/build/net/9p/9pnet.ko found: /lib/modules/3.4.0-gentoo/kernel/fs/9p/9p.ko found: /lib/modules/3.4.0-gentoo/source/fs/9p/9p.ko found: /lib/modules/3.4.0-gentoo/build/fs/9p/9p.ko found: /lib/modules/3.4.0-gentoo/kernel/net/9p/9pnet_virtio.ko found: /lib/modules/3.4.0-gentoo/source/net/9p/9pnet_virtio.ko found: /lib/modules/3.4.0-gentoo/build/net/9p/9pnet_virtio.ko The next problem was the following: dmns libvirt-sandbox # virt-sandbox -c qemu:///system -n test123 -v -d /usr/bin/yes Unable to start sandbox: Failed to create domain: internal error Process exited while reading console log output: char device redirected to /dev/pts/1 char device redirected to /dev/pts/3 Virtio-9p Failed to initialize fs-driver with id:fsdev-fs1 and export path:libvirt-sandbox/test123/config It appears when running as root because of the following line: ./libvirt-sandbox/libvirt-sandbox-context.c: cachedir = (getuid() ? g_get_user_cache_dir() : RUNDIR); RUNDIR is always "" due to being compiled with -DRUNDIR=\"\" . This is because there's a typo in makefile.am Both of these are fixed in the diff attachment. Having these fixes in place everything works fine when using libvirt 0.9.10 but for newer versions I noticed every time I ran virt-sandbox the libvirtd daemon would segfault. Using git bisect I traced the problem back to commit [1]. So I reverted back to libvirt 0.9.10 but I believe there is a problem both in the commit and somewhere in libvirt-sandbox. Please have a look and tell me if you need extra info. [1] http://libvirt.org/git/?p=libvirt.git;a=commit;h=4716138229ae47c5492c13a862… Radu Caragea.

[libvirt] [PATCH 0/2] Don't overwrite security labels

If we have a running domain A with a PCI/USB device X passthrough, and user wants to start domain B with again device X, we reject start however, call qemuProcessStop to perform rollback. This however does not do any rollback just cleanup therefore rewrite labels on device X leaving domain A in silly situation.

[libvirt] [PATCH] virsh: let 'connect' without args remember -c option
by Eric Blake 12 Jun '12

12 Jun '12

If a user invokes 'virsh -c $URI', then within that batch shell, they probably want 'connect' to revert to $URI rather than the normal default URI you get for passing in NULL. In particular, I had a setup where qemu:///session was failing, but took 20 seconds to fail; since 'make -C tests check TESTS=virsh-all' exercises the command 'virsh -c test:///default connect' without arguments, it was locking up for 20 seconds trying to connect to qemu, even though the testsuite specifically wants to limit itself to the test:///default URI. * tools/virsh.c (__vshControl): Add member. (main, vshParseArgv): Set it. (vshDeinit): Clean it up. (cmdConnect): Use it to reopen to original connection. --- This doesn't fix the root cause of this problem: https://www.redhat.com/archives/libvir-list/2012-June/msg00237.html but at least it makes my 'make check' runs faster while I still investigate the root problem. tools/virsh.c | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) diff --git a/tools/virsh.c b/tools/virsh.c index 0453b95..b28dc49 100644 --- a/tools/virsh.c +++ b/tools/virsh.c @@ -241,6 +241,7 @@ typedef struct __vshCmd { */ typedef struct __vshControl { char *name; /* connection name */ + char *default_name; /* -c or env-var default when name is NULL */ virConnectPtr conn; /* connection to hypervisor (MAY BE NULL) */ vshCmd *cmd; /* the current command */ char *cmdstr; /* string with command */ @@ -856,7 +857,7 @@ cmdConnect(vshControl *ctl, const vshCmd *cmd) vshError(ctl, "%s", _("Please specify valid connection URI")); return false; } - ctl->name = vshStrdup(ctl, name); + ctl->name = vshStrdup(ctl, name ? name : ctl->default_name); ctl->useGetInfo = false; ctl->useSnapshotOld = false; @@ -19922,6 +19923,7 @@ vshDeinit(vshControl *ctl) vshReadlineDeinit(ctl); vshCloseLogFile(ctl); VIR_FREE(ctl->name); + VIR_FREE(ctl->default_name); if (ctl->conn) { int ret; if ((ret = virConnectClose(ctl->conn)) != 0) { @@ -20176,7 +20178,8 @@ vshParseArgv(vshControl *ctl, int argc, char **argv) ctl->timing = true; break; case 'c': - ctl->name = vshStrdup(ctl, optarg); + VIR_FREE(ctl->default_name); + ctl->default_name = vshStrdup(ctl, optarg); break; case 'v': if (STRNEQ_NULLABLE(optarg, "long")) { @@ -20211,6 +20214,7 @@ vshParseArgv(vshControl *ctl, int argc, char **argv) exit(EXIT_FAILURE); } } + ctl->name = vshStrdup(ctl, ctl->default_name); if (argc > optind) { /* parse command */ @@ -20268,7 +20272,7 @@ main(int argc, char **argv) progname++; if ((defaultConn = getenv("VIRSH_DEFAULT_CONNECT_URI"))) { - ctl->name = vshStrdup(ctl, defaultConn); + ctl->default_name = vshStrdup(ctl, defaultConn); } if (!vshParseArgv(ctl, argc, argv)) { -- 1.7.10.2

[libvirt] libvirt modification
by Patrick Raad 12 Jun '12

12 Jun '12

Hello, I am not that expert in development, but I am working on a project for migrating VM between hosts and I need to add a function to libvirt in order to send a certain message. What I am using is KVM-qemu as a hypervisor. When a VM "live" migrates from a host A to a host B, I need that the host B sends a certain message through a socket, once the live migration has been successfully completed and the VM is running on host B. Can you please tell me which file I must modify in order to add my function? What does libvirt uses to notify the destination that the migration is completed. I thought about modifying qemu_migration.c, but it didn't seem to work, so I was thinking about using virsh.c, but this way the destination host won't be notified so I don't think it can work... Any ideas?? Thank you -- Patrick RAAD

[libvirt] [PATCH 0/7] Introduce API for dumping domain IP addresses
by Michal Privoznik 12 Jun '12

12 Jun '12

This feature has been requested for a very long time. However, we had to wait for guest agent to obtain reliable results as user might create totally different structure of interfaces than seen from outside (e.g. bonding, virtual interfaces, etc.). That's the main reason why sniffing for domain traffic can return bogus results. Fortunately, qemu guest agent implement requested part for a while so nothing holds us back anymore. To make matters worse, guest OS can assign whatever name to an interface and changing MAC inside guest isn't propagated to the host which in the end see original one. Therefore, finding correlation between interface within guest and the host side end is left as exercise for mgmt applications. This API is called virDomainInterfacesAddresses (okay, maybe too many plurals) and returns a dynamically allocated array of virDomainInterface struct. The great disadvantage once this gets released, it's written in stone and we cannot change or add an item into it. Therefore we might add a padding into it - something like reserved for future use. On the other hand, everything important is already there - what else we will want to add? :) There are basically two approaches: 1) two APIs: one for list interfaces names, the other for querying addresses on singe interface 2) one API that returns everything I've chosen the latter as it's race free (query for interface that has gone meanwhile). Michal Privoznik (7): Introduce virDomainInterfacesAddresses API virsh: Expose virDomainInterfacesAddresses qemu_agent: Implement 'guest-network-get-interfaces' command handling qemu: Implement virDomainInterfacesAddresses remote: Implement virDomainInterfacesAddresses python: Expose virDomainInterfacesAddresses python: create example for dumping domain IP addresses daemon/remote.c | 122 ++++++++++++++++++++++++++++++ examples/python/Makefile.am | 2 +- examples/python/README | 1 + examples/python/domipaddrs.py | 50 ++++++++++++ include/libvirt/libvirt.h.in | 32 ++++++++ python/generator.py | 1 + python/libvirt-override-api.xml | 6 ++ python/libvirt-override.c | 116 ++++++++++++++++++++++++++++ src/driver.h | 6 ++ src/libvirt.c | 101 +++++++++++++++++++++++++ src/libvirt_public.syms | 5 + src/qemu/qemu_agent.c | 158 +++++++++++++++++++++++++++++++++++++++ src/qemu/qemu_agent.h | 4 + src/qemu/qemu_driver.c | 76 +++++++++++++++++++ src/remote/remote_driver.c | 95 +++++++++++++++++++++++ src/remote/remote_protocol.x | 25 ++++++- tools/virsh.c | 92 +++++++++++++++++++++++ tools/virsh.pod | 10 +++ 18 files changed, 900 insertions(+), 2 deletions(-) create mode 100644 examples/python/domipaddrs.py -- 1.7.8.5

[libvirt] [PATCH] docs: minor fixes to domain interface documentation

11 Jun '12

A few examples for <interface> had a type='direct' interface with no sub-elements. This is not allowed - a type='direct' interface must have at least a source element. (Most likely the example was copied from the type='user' or type='ethernet' examples - they *do* allow an instance with no sub-elements).

[libvirt] [PATCH] nwfilter: Display detected IP address in domain XML
by Stefan Berger 11 Jun '12

11 Jun '12

Display detected IP addresses in the domain XML using the IP_LEASE variable name. This variable name now becomes a reserved variable name that can be read only but not set by the user. The format of the value is: <ip address>,<lease timeout in seconds> An example of a displayed XML may then be: <interface type='bridge'> <mac address='52:54:00:68:e3:90'/> <source bridge='virbr0'/> <target dev='vnet1'/> <model type='virtio'/> <filterref filter='clean-traffic'> <parameter name='CTRL_IP_LEARNING' value='dhcp'/> <parameter name='IP_LEASE' value='192.168.122.210,100'/> </filterref> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </interface> This patch now also offers a better (libvirt-internal) API for accessing the detected IP addresses. The function virDomainConfNWFilterGetLeases can be used to retrieve a list of IP leases associated with a given interface. This function will then either retrieve the data from the DHCP snooping or IP learning subsystems, depending on which detection algorithm has been activated. If none is active, a NULL pointer for the array of leases will be returned. --- PS: This is the last remaining patch of the DHCP snooping series.

My latest patch for RPC rework (a2c304f6872) introduced a memory leak. virNetMessageEncodeHeader() is calling VIR_ALLOC_N(msg->buffer, ...) despite fact, that msg->buffer isn't VIR_FREE()'d on all paths calling the function.

[libvirt] [PATCH] snapshot: avoid virsh crash with older servers

Commits 51082301, 16d7b39, and 521cc447 introduced support for 'virsh snapshot-list --from' when talking to a server older than 0.9.5, but broke support for plain 'virsh snapshot-list' for the same old server in the process.

[libvirt] Multiple KVM virtio console is not working.
by Pankaj Rawat 11 Jun '12

11 Jun '12

Let me explain our scenario: We need to provide multiple console options so that from Host, user can login into the KVM guest using different console. Environment - Fedora 17 (Host), Fedora 17 (Guest) Libvirt version installed - 0.9.11 On Host, we have edit the guest XMl file and added for the multiple virtio console entry: <console type='pty'> <target type='virtio'/> </console> <console type='pty'> <target type='virtio'/> </console> We are able to connect to guest via serial console device. works fine. #virsh console guest We are unable to connect to guest via virtio console. Not working. #virsh console --devname console1 guest We login using the serial console into guest and check the lsmod command, So the virtio console driver module is not loaded. Also the getty process is not running for different virtio console devices. So i manually load the virtio console (virtio_console.ko) module -> Even then i am unable to login using the virtio console. In the guest, /dev/hvc[0-7] is present. Pls tell us whether we are missing any configuration or settings on Host/Guest side.

[libvirt] [PATCH 1/2] Add VSCSI bus type and VSCSI controller type for pseries guest.
by Li Zhang 10 Jun '12

10 Jun '12

Now, there is only SCSI bus and controller type in libvirt. And when configuring VSCSI controller, it needs to configure the spapr-vio bus address type externally. It's a little inconvenient to configure the controller type. This patch is to add VSCSI bus type and VSCSI controller type. And handle with the problems when VSCSI and SCSI devices working together, by assign the even number to index of VSCSI controller and odd number to index of SCSI controller. And when the VSCSI controller is always assigned as SPAPRVIO bus address type and SCSI controller will be always assigned as PCI bus address, which is implemented according to the controllers' type. So when one disk is based on VSCSI controller, then assign the bus as 'vscsi', and one right VSCSI controller will be selected. If one disk is based on VSCSI controller, the XML file is as the following: <disk type='file' device='disk' > <driver name='qemu' type='raw'/> <source file='/path/file'/> <target dev='sda' bus='vscsi'/> </disk> VSCSI controllers' configuration in XML file will be like this: <controller type='vscsi' index='0'> </controller> If one disk is based on 'vscsi', the 'vscsi' bus should be assigned externally. Otherwise, it will be set as 'scsi' bus according to the 'sd' target prefix of the disk.

[libvirt] [PATCH] Add some missing hook functions
by Daniel P. Berrange 10 Jun '12

10 Jun '12

From: "Daniel P. Berrange" <berrange(a)redhat.com> A core use case of the hook scripts is to be able to do things to a guest's network configuration. It is possible to hook into the 'start' operation for a QEMU guest which runs just before the guest is started. The TAP devices will exist at this point, but the QEMU process will not.

If libvirtd is restarted it will re-populate firewall rules, but there is no QEMU hook to trigger for existing domains. This is solved with a 'reconnect' hook.

[libvirt] [PATCH V14 0/5] Add DHCP snooping support to nwfilter
by Stefan Berger 10 Jun '12

10 Jun '12

This series of patches adds DHCP snooping support to libvirt's nwfilter subsystem. DHCP snooping detects DHCP leases obtained by a VM and automatically adjusts the network traffic filters to reflect the IP addresses with which a VM may send its traffic, thus for example preventing IP address spoofing. Once leases on IP addresses expire or if a VM gives up on a lease on an IP address, the filters are also adjusted. All leases are persisted and automatically applied upon a VM's restart. Leases are associated with the tuple of VM-UUID and interface MAC address. The following interface XML activates and uses the DHCP snooping: <interface type='bridge'> <source bridge='virbr0'/> <filterref filter='clean-traffic'> <parameter name='CTRL_IP_LEARNING' value='dhcp'/> </filterref> </interface> Once an IP address has been detected on an interface, 'virsh dumpxml <vm>' would show the IP address lease in the format <IP address>,<lease timeout in seconds>: <interface type='bridge'> <source bridge='virbr0'/> <filterref filter='clean-traffic'> <parameter name='CTRL_IP_LEARNING' value='dhcp'/> <parameter name='IP_LEASE' value='192.168.122.210,180'/> </filterref> </interface> Regards, David and Stefan v14: - addressed Eric Blake's concerns - introducing a typedef for MAC addresses

[libvirt] [PATCHv2 0/9] API to list all domains
by Peter Krempa 10 Jun '12

Second version of the atomic listing API.

Hi, I want to remove TLS from libvirt (0.8.4). I ran across this earlier thread on the same topic: http://www.redhat.com/archives/libvir-list/2012-January/msg00479.html ...just curious if any further development occurred in this area since then? ie, support for a --without-gnutls compiler option.

Hi list, I write virtualization docs for Red Hat and would like to maintain this guide[1] - it's in need of a bit of attention. I have publican and the publican brand up and running, and have already cloned the git repo, but I would appreciate some help on how to get commit access, or any other pertinent info I should be aware of before getting started. Any comments on the guide (ideas for new sections, future trends for libvirt app development, parts that are plain wrong) would be more than welcome! A Red Hat Bugzilla component is set up for this guide: doc-Libvirt_Application_Development_Guide (under the Red Hat Enterprise Linux 6 product).

[libvirt] pointless time-consuming test 'virsh-all'
by Eric Blake 08 Jun '12

08 Jun '12

The command 'make -C tests check' takes forever, because it is calling this lengthy virsh command and ignoring the failures: $ time tools/virsh -c test:///default connect error: Failed to connect to the hypervisor error: Failed to connect socket to '/run/user/eblake/libvirt/libvirt-sock': No such file or directory real 0m21.070s user 0m0.027s sys 0m0.036s The test looks quite broken - ALL it is currently doing is wasting 21 seconds on this one iteration, because it ignores output and exit status (what else _is_ there, besides effects to the file system)? Any volunteers to clean this test up into something that actually does something useful? -- Eric Blake eblake(a)redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org

I'm out of my field there, those questions are for Luiz and the libvirt guys to answer.

[libvirt] CPU topology 'sockets' handling guest vs host
by Daniel P. Berrange 08 Jun '12

08 Jun '12

On my x86_64 host I have a pair of Quad core CPUs, each in a separate NUMA node. The virsh capabilities topology data reports this: # virsh capabilities | xmllint --xpath /capabilities/host/cpu - <cpu> <arch>x86_64</arch> <model>Opteron_G3</model> <vendor>AMD</vendor> <topology sockets="1" cores="4" threads="1"/> <feature name="osvw"/> <feature name="3dnowprefetch"/> <feature name="cr8legacy"/> <feature name="extapic"/> <feature name="cmp_legacy"/> <feature name="3dnow"/> <feature name="3dnowext"/> <feature name="pdpe1gb"/> <feature name="fxsr_opt"/> <feature name="mmxext"/> <feature name="ht"/> <feature name="vme"/> </cpu> # virsh capabilities | xmllint --xpath /capabilities/host/topology - <topology> <cells num="2"> <cell id="0"> <cpus num="4"> <cpu id="0"/> <cpu id="1"/> <cpu id="2"/> <cpu id="3"/> </cpus> </cell> <cell id="1"> <cpus num="4"> <cpu id="4"/> <cpu id="5"/> <cpu id="6"/> <cpu id="7"/> </cpus> </cell> </cells> </topology> Note, it is reporting sockets=1, because sockets is the number of sockets *per* NUMA node. Now I try to figure the guest to match the host using: <cpu> <topology sockets='1' cores='4' threads='1'/> <numa> <cell cpus='0-3' memory='512000'/> <cell cpus='4-7' memory='512000'/> </numa> </cpu> And I get: error: Maximum CPUs greater than topology limit So, the XML checker is mistaking 'sockets' as the total number of sockets, rather than the per-node socket count.

[libvirt] [PATCH 1/1] Assign correct address type to spapr-vlan and spapr-vty.
by Li Zhang 07 Jun '12

07 Jun '12

For pseires guest, spapr-vlan and spapr-vty is based on spapr-vio address. According to model of network device, the address type should be assigned automatically. For serial device, serial pty device is recognized as spapr-vty device, which is also on spapr-vio. So this patch is to correct the address type of spapr-vlan and spapr-vty, and build correct command line of spapr-vty.

[libvirt] [PATCH] command: avoid potential deadlock on handshake
by Eric Blake 07 Jun '12

07 Jun '12

Similar to commit 858c247, the parent process should close it's copy of the end of the pipe given to the child; otherwise, if there is an extreme bug where the parent thinks the child reported an error and is waiting for the message to go along with it, but the child thinks it reported success and is waiting for the parent to acknowledge the success, we would get into deadlock. Thankfully, I don't think this deadlock is possible without at least one other bug in the code, but I did see exactly that sort of situation prior to commit da831af - if a double close bug in the parent causes the parent to read the wrong fd, it might assume the child failed, even though the child really sent success if only the parent had read from the correct location. * src/util/command.c (virCommandHandshakeWait): Close unused fds sooner. --- src/util/command.c | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/src/util/command.c b/src/util/command.c index 62ea50b..62848cd 100644 --- a/src/util/command.c +++ b/src/util/command.c @@ -2507,6 +2507,11 @@ int virCommandHandshakeWait(virCommandPtr cmd) VIR_FORCE_CLOSE(cmd->handshakeWait[0]); return -1; } + /* Close the handshakeNotify fd before trying to read anything + * further on the handshakeWait pipe; so that a child waiting + * on our acknowledgment will die rather than deadlock. */ + VIR_FORCE_CLOSE(cmd->handshakeNotify[1]); + if ((len = saferead(cmd->handshakeWait[0], msg, 1024)) < 0) { VIR_FORCE_CLOSE(cmd->handshakeWait[0]); VIR_FREE(msg); -- 1.7.10.2

[libvirt] RFC: TODO list for a 1.0 release
by Daniel P. Berrange 07 Jun '12

07 Jun '12

We have mentioned a 1.0 release in passing a few times recently but we have never really set out a clear list of goals for such a notable release. This thread is an attempt to clarify such goals. To avoid making the 1.0 target too hard, we should aim for as *little* as possible on our TODO list. I think the priority here should be on public API level things, or core libvirt infrastructure, and not random impl details of specific hypervisors. In particular I think we should focus on things that make libvirt better to develop app against. IMHO we should have the following things in the 1.0 release - List object APIs which directly return the object instance https://bugzilla.redhat.com/show_bug.cgi?id=636096 * virConnectListAllDomains * virConnectListAllInterfaces * virConnectListAllNetworks * virConnectListAllNWFIlters * virConnectListAllNodeDevices * virConnectListAllSecrets * virConnectListAllStoragePools * virDomainListAllSnapshots * virStoragePoolListAllVolumes NB: with support across LXC, UML, Xen, LibXL, QEMU & ESX - Lifecycle events for all top level objects https://bugzilla.redhat.com/show_bug.cgi?id=636027 * virConnectInterfaceEventRegisterAny * virConnectNetworkEventRegisterAny * virConnectNWFilterEventRegisterAny * virConnectNodeDeviceEventRegisterAny * virConnectSecretEventRegisterAny * virConnectStoragePoolEventRegisterAny - Fine grained access control https://bugzilla.redhat.com/show_bug.cgi?id=636148 * Access control infrastructure * PolicyKit driver impl * Simple RBAC driver impl * SELinux driver impl (probably not needed for 1.0) Do you have suggestions for anything else that you think is very important for libvirt ?

[libvirt] [PATCH] util: Fix deadlock in virLogReset
by Jiri Denemark 07 Jun '12

07 Jun '12

When libvirtd forks off a new child, the child then calls virLogReset(), which ends up closing file descriptors used as log outputs. However, we recently started logging closed file descriptors, which means we need to lock logging mutex which was already logged by virLogReset(). We don't really want to log anything when we are in the process of closing log outputs. --- src/util/logging.c | 5 +++-- src/util/virfile.c | 28 ++++++++++++++++------------ src/util/virfile.h | 22 ++++++++++++++++++---- 3 files changed, 37 insertions(+), 18 deletions(-) diff --git a/src/util/logging.c b/src/util/logging.c index 23778d3..cf62184 100644 --- a/src/util/logging.c +++ b/src/util/logging.c @@ -864,10 +864,11 @@ static int virLogOutputToFd(const char *category ATTRIBUTE_UNUSED, return ret; } -static void virLogCloseFd(void *data) { +static void virLogCloseFd(void *data) +{ int fd = (intptr_t) data; - VIR_FORCE_CLOSE(fd); + VIR_LOG_CLOSE(fd); } static int virLogAddOutputToStderr(int priority) { diff --git a/src/util/virfile.c b/src/util/virfile.c index a0000d0..6c69217 100644 --- a/src/util/virfile.c +++ b/src/util/virfile.c @@ -43,7 +43,7 @@ __FUNCTION__, __LINE__, __VA_ARGS__) -int virFileClose(int *fdptr, bool preserve_errno, bool ignore_EBADF) +int virFileClose(int *fdptr, virFileCloseFlags flags) { int saved_errno = 0; int rc = 0; @@ -51,24 +51,28 @@ int virFileClose(int *fdptr, bool preserve_errno, bool ignore_EBADF) if (*fdptr < 0) return 0; - if (preserve_errno) + if (flags & VIR_FILE_CLOSE_PRESERVE_ERRNO) saved_errno = errno; rc = close(*fdptr); - if (rc < 0) { - if (errno == EBADF) { - if (!ignore_EBADF) - VIR_WARN("Tried to close invalid fd %d", *fdptr); + + if (!(flags & VIR_FILE_CLOSE_DONT_LOG)) { + if (rc < 0) { + if (errno == EBADF) { + if (!(flags & VIR_FILE_CLOSE_IGNORE_EBADF)) + VIR_WARN("Tried to close invalid fd %d", *fdptr); + } else { + char ebuf[1024] ATTRIBUTE_UNUSED; + VIR_DEBUG("Failed to close fd %d: %s", + *fdptr, virStrerror(errno, ebuf, sizeof(ebuf))); + } } else { - char ebuf[1024] ATTRIBUTE_UNUSED; - VIR_DEBUG("Failed to close fd %d: %s", - *fdptr, virStrerror(errno, ebuf, sizeof(ebuf))); + VIR_DEBUG("Closed fd %d", *fdptr); } - } else { - VIR_DEBUG("Closed fd %d", *fdptr); } *fdptr = -1; - if (preserve_errno) + + if (flags & VIR_FILE_CLOSE_PRESERVE_ERRNO) errno = saved_errno; return rc; diff --git a/src/util/virfile.h b/src/util/virfile.h index c033248..6882a73 100644 --- a/src/util/virfile.h +++ b/src/util/virfile.h @@ -31,16 +31,21 @@ # include "internal.h" # include "ignore-value.h" +typedef enum virFileCloseFlags { + VIR_FILE_CLOSE_PRESERVE_ERRNO = 1 << 0, + VIR_FILE_CLOSE_IGNORE_EBADF = 1 << 1, + VIR_FILE_CLOSE_DONT_LOG = 1 << 2, +} virFileCloseFlags; /* Don't call these directly - use the macros below */ -int virFileClose(int *fdptr, bool preserve_errno, bool ignore_EBADF) +int virFileClose(int *fdptr, virFileCloseFlags flags) ATTRIBUTE_RETURN_CHECK; int virFileFclose(FILE **file, bool preserve_errno) ATTRIBUTE_RETURN_CHECK; FILE *virFileFdopen(int *fdptr, const char *mode) ATTRIBUTE_RETURN_CHECK; /* For use on normal paths; caller must check return value, and failure sets errno per close. */ -# define VIR_CLOSE(FD) virFileClose(&(FD), false, false) +# define VIR_CLOSE(FD) virFileClose(&(FD), 0) # define VIR_FCLOSE(FILE) virFileFclose(&(FILE), false) /* Wrapper around fdopen that consumes fd on success. */ @@ -48,12 +53,21 @@ FILE *virFileFdopen(int *fdptr, const char *mode) ATTRIBUTE_RETURN_CHECK; /* For use on cleanup paths; errno is unaffected by close, and no return value to worry about. */ -# define VIR_FORCE_CLOSE(FD) ignore_value(virFileClose(&(FD), true, false)) +# define VIR_FORCE_CLOSE(FD) \ + ignore_value(virFileClose(&(FD), VIR_FILE_CLOSE_PRESERVE_ERRNO)) # define VIR_FORCE_FCLOSE(FILE) ignore_value(virFileFclose(&(FILE), true)) /* Similar VIR_FORCE_CLOSE() but ignores EBADF errors since they are expected * during mass close after fork(). */ -# define VIR_MASS_CLOSE(FD) ignore_value(virFileClose(&(FD), true, true)) +# define VIR_MASS_CLOSE(FD) \ + ignore_value(virFileClose(&(FD), \ + VIR_FILE_CLOSE_PRESERVE_ERRNO | \ + VIR_FILE_CLOSE_IGNORE_EBADF)) + +# define VIR_LOG_CLOSE(FD) \ + ignore_value(virFileClose(&(FD), \ + VIR_FILE_CLOSE_PRESERVE_ERRNO | \ + VIR_FILE_CLOSE_DONT_LOG)) /* Opaque type for managing a wrapper around a fd. */ struct _virFileWrapperFd; -- 1.7.10.2

[libvirt] [PATCH] qemu: better detection of crashed domains

When libvirtd is started and there is an unusable/not-connectable leftover from earlier started machine, it's more reasonable to say that the machine "crashed" if we know it was started with "-no-shutdown". This patch fixes that and also changes the other result (when machine was started without "-no-shutdown") to "unknown", because the previous "failed" reason means (according to include/libvirt/libvirt.h.in:174), that the machine failed to start. --- src/qemu/qemu_process.c | 12 +++++++++++- 1 files changed, 11 insertions(+), 1 deletions(-) diff --git a/src/qemu/qemu_process.c b/src/qemu/qemu_process.c index 2adf570..604c31b 100644 --- a/src/qemu/qemu_process.c +++ b/src/qemu/qemu_process.c @@ -3141,7 +3141,17 @@ error: * to remove danger of it ending up running twice if * user tries to start it again later */ - qemuProcessStop(driver, obj, 0, VIR_DOMAIN_SHUTOFF_FAILED); + if (qemuCapsGet(priv->qemuCaps, QEMU_CAPS_NO_SHUTDOWN)) + /* If we couldn't get the monitor and qemu supports + * no-shutdown, we can safely say that the domain + * crashed ... */ + state = VIR_DOMAIN_SHUTOFF_CRASHED; + else + /* ... but if it doesn't we can't say what the state + * really is and FAILED means "failed to start" */ + state = VIR_DOMAIN_SHUTOFF_UNKNOWN; + + qemuProcessStop(driver, obj, 0, state); if (!obj->persistent) qemuDomainRemoveInactive(driver, obj); else -- 1.7.8.6

[libvirt] [PATCH 0/3] openvz: allow for runtime quota updates
by Guido Günther 06 Jun '12

06 Jun '12

Hi, attached patches allow to change disk quota at runtime. This can later be extended to update network configuration as well. The patch revealed a problem of the openvz driver in genral: the openvzLoadDomains only reads the on disk configuration but doesn't check if running domains have (non persistent) diverging values due to openvz calls without the "--save" option but that's part of another patch.

Hello All, Can some one let me know if we have the latest libvirt version for RHEL 6.1 which would provided me Memory related counters/metrics. The latest libvirt which I found was on Fedora. Any pointer or expected dates of libvirt release on RHEL would be highly appreciated.

[libvirt] Schedule of next release
by Daniel Veillard 05 Jun '12

05 Jun '12

I just looked and we are at 142 patches since the 0.9.12 release. If we were to keep the 1 month between releases schedule we would need to enter freeze at the end of the week, and that mean a relatively small release next. So I suggests to delay the release by 2 more weeks which also has the advantage to get back to the end of the month deadline which is easy to remember. So unless there is a pressing issue to make a release soon which I don't know about, let's plan to enter freeze around Jun 22 for a release at the end of month. As a note it seems that the rate of changes to libvirt is decreasing a bit (see http://veillard.com/commits_by_year_month.png which I generated at the end of may with gitstats) so maybe we should start planning for slighty longuer release cycles. Let's see how the trend evolves, but I doubt the rate wil increase over the summer :-) Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel(a)veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] [PATCH v3 0/2] Rework RPC message buffer
by Michal Privoznik 05 Jun '12

05 Jun '12

This patch set tries to fix corner cases where libvirt runs on huge system, e.g. 4K CPU monster. In these cases, capabilities XML is enormously big, as we are transferring info about each singe CPU core (to which NUMA node it belongs, etc.). This XML is bigger than our RPC limit, therefore users cannot get it as it is dropped on server, leaving them with inability to connect. Therefore we need to increase those limits (whole RPC message and RPC string). However, simple lifting up will work, but increase mem usage. Therefore I've reworked RPC buffer handling: changed it from 'statically' to dynamically allocated. So in most cases - when small messages are sent - this will even decrease our memory consumption. Leaving us flexible for corner cases described above. On the other hand, I realize we've had our history with RPC breakage. So I think I'll require more than 1 ACK before pushing. (I guess Eric's ACK still holds) diff to v2: -suggestions from Eric's review included diff to v1: -couple of fixes (1/2) -increased other limits as well (2/2) Michal Privoznik (2): rpc: Switch to dynamically allocated message buffer rpc: Size up RPC limits src/libvirt.c | 2 + src/remote/remote_protocol.x | 20 +- src/rpc/virnetclient.c | 16 ++- src/rpc/virnetmessage.c | 12 ++- src/rpc/virnetmessage.h | 5 +- src/rpc/virnetprotocol.x | 6 +- src/rpc/virnetserverclient.c | 24 +++- tests/virnetmessagetest.c | 393 +++++++++++++++++++++++------------------- 8 files changed, 281 insertions(+), 197 deletions(-) -- 1.7.8.5

[libvirt] [PATCH] build: fix 'make distcheck' issues
by Eric Blake 05 Jun '12

05 Jun '12

We have a distributed file depending on a generated file, which is a no-no for a VPATH build from a read-only source tree (no wonder 'make distcheck' gives us precisely that situation): File `libvirt_driver_remote.la' does not exist. File `libvirt_driver_remote_la-remote_driver.lo' does not exist. Prerequisite `libvirt_probes.h' is newer than target `../../src/remote/remote_protocol.h'. Must remake target `../../src/remote/remote_protocol.h'. Invoking recipe from Makefile:7464 to update target `../../src/remote/remote_protocol.h'. make[3]: Entering directory `/home/remote/eblake/libvirt-tmp2/build/libvirt-0.9.12/_build/src' GEN ../../src/remote/remote_protocol.h cannot create ../../src/remote/remote_protocol.h: Permission denied at ../../src/rpc/genprotocol.pl line 31. make[3]: *** [../../src/remote/remote_protocol.h] Error 13 Rather than making distributed .c files depend on generated files, we really want to ensure that compilation into .lo files is not attempted until the generated files are present, done by this patch. After that fix, the next issue was that make treats './foo' and 'foo' differently in determining whether an implicit %foo rule is applicable. Also, the output for using the .aug test files was a bit verbose. After fixing that, the next error is related to the docs directory, where the tarball is missing a stamp file and thus tries to regenerate files that are already present: GEN ../../docs/apibuild.py.stamp Traceback (most recent call last): File "../../docs/apibuild.py", line 2511, in <module> rebuild("libvirt") File "../../docs/apibuild.py", line 2495, in rebuild builder.serialize() File "../../docs/apibuild.py", line 2424, in serialize output = open(filename, "w") IOError: [Errno 13] Permission denied: '../../docs/libvirt-api.xml' make[5]: *** [../../docs/apibuild.py.stamp] Error 1 and fixing that exposed another case of a distributed file (generated html) depending on a built file (libvirt.h). * src/Makefile.am ($(srcdir)/remote/remote_driver.c): Change...

[libvirt] [PATCH] Fix for parallel port passtrough for QEMU
by Beat.Joerg＠ssatr.ch 05 Jun '12

05 Jun '12

Hi As requested by Dave, I send this to the list. I came across a bug that the command line generated for passtrough of the host parallel port /dev/parport0 by libvirt for QEMU is incorrect. It currently produces: -chardev tty,id=charparallel0,path=/dev/parport0 -device isa-parallel,chardev=charparallel0,id=parallel0 The first parameter is "tty". It sould be "parport". If I launch qemu with -chardev parport,... it works as expected. I have already filled a bug report ( https://bugzilla.redhat.com/show_bug.cgi?id=823879 ), the topic was already on the list some months ago: https://www.redhat.com/archives/libvirt-users/2011-September/msg00095.html Not sure if this is fix is very clean, but for my case it works. Perhaps it should also be checked if similar problems / patches are required for other chardev backends. Kind regards Beat diff -Naur libvirt-0.9.4.orig/src/qemu/qemu_command.c libvirt-0.9.4/src/qemu/qemu_command.c --- libvirt-0.9.4.orig/src/qemu/qemu_command.c 2012-05-22 13:40:16.788633656 +0200 +++ libvirt-0.9.4/src/qemu/qemu_command.c 2012-05-22 13:52:18.453608557 +0200 @@ -2357,8 +2357,14 @@ break; case VIR_DOMAIN_CHR_TYPE_DEV: - virBufferAsprintf(&buf, "tty,id=char%s,path=%s", alias, - dev->data.file.path); + if (STRPREFIX(dev->data.file.path, "/dev/parport")) { + virBufferAsprintf(&buf, "parport,id=char%s,path=%s", alias, + dev->data.file.path); + } + else { + virBufferAsprintf(&buf, "tty,id=char%s,path=%s", alias, + dev->data.file.path); + } break; case VIR_DOMAIN_CHR_TYPE_FILE:

[libvirt] [PATCH] command: avoid deadlock on EPIPE situation
by Eric Blake 04 Jun '12

04 Jun '12

It is possible to deadlock libvirt by having a domain with XML longer than PIPE_BUF, and by writing a hook script that closes stdin early. This is because libvirt was keeping a copy of the child's stdin read fd open, which means the write fd in the parent will never see EPIPE (remember, libvirt should always be run with SIGPIPE ignored, so we should never get a SIGPIPE signal). Since there is no error, libvirt blocks waiting for a write to complete, even though the only reader is also libvirt. The solution is to ensure that only the child can act as a reader before the parent does any writes; and then dealing with the fallout of dealing with EPIPE. Thankfully, this is not a security hole - since the only way to trigger the deadlock is to install a custom hook script, anyone that already has privileges to install a hook script already has privileges to do any number of other equally disruptive things to libvirt; it would only be a security hole if an unprivileged user could install a hook script to DoS a privileged user. * src/util/command.c (virCommandRun): Close parent's copy of child read fd earlier. (virCommandProcessIO): Don't let EPIPE be fatal; the child may be done parsing input. * tests/commandhelper.c (main): Set up a SIGPIPE situation. * tests/commandtest.c (test20): Trigger it. * tests/commanddata/test20.log: New file. --- I tested this by using just the changes to 'tests/', and was able to trigger deadlock in 100% of my testing with the buffer lengths shown here. src/util/command.c | 22 +++++++++++++--------- tests/commanddata/test20.log | 13 +++++++++++++ tests/commandhelper.c | 6 ++++++ tests/commandtest.c | 42 ++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 74 insertions(+), 9 deletions(-) create mode 100644 tests/commanddata/test20.log diff --git a/src/util/command.c b/src/util/command.c index ba43078..52a457c 100644 --- a/src/util/command.c +++ b/src/util/command.c @@ -1738,7 +1738,7 @@ virCommandProcessIO(virCommandPtr cmd, int *inpipe) break;

[libvirt] [PATCH] qemu: Move -name arg to be the 1st so it's visible in "ps x"
by Marti Raudsepp 01 Jun '12

01 Jun '12

Hi list, Currently, monitoring QEMU virtual machines with standard Unix sysadmin tools is harder than it has to be. The QEMU command line is often miles long and mostly redundant, it's hard to tell which process is which. This patch reorders the QEMU -name argument to be the first, so it's immediately visible in "ps x", htop and "atop -c" output. Patch attached and also available from my github fork (master @ git://github.com/intgr/libvirt.git) Regards, Marti

[libvirt] [PATCH] qemu: fix netdev alias name assignment wrt type='hostdev'
by Laine Stump 01 Jun '12

01 Jun '12

This patch resolves: https://bugzilla.redhat.com/show_bug.cgi?id=827519 The problem is that an interface with type='hostdev' will have an alias of the form "hostdev%d", while the function that looks through existing netdevs to determine the name to use for a new addition will fail if there's an existing entry that does not match the form "net%d". This is another of the handful of places that need an exception due to the hybrid nature of <interface type='hostdev'> (which is not exactly an <interface> or a <hostdev>, but is both at the same time). --- src/qemu/qemu_command.c | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index 9f99dce..1a240fb 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -548,6 +548,11 @@ qemuAssignDeviceNetAlias(virDomainDefPtr def, virDomainNetDefPtr net, int idx) idx = 0; for (i = 0 ; i < def->nnets ; i++) { int thisidx; + + if (def->nets[i]->type == VIR_DOMAIN_NET_TYPE_HOSTDEV) { + /* type='hostdev' interfaces have a hostdev%d alias */ + continue; + } if ((thisidx = qemuDomainDeviceAliasIndex(&def->nets[i]->info, "net")) < 0) { qemuReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("Unable to determine device index for network device")); -- 1.7.10.2

[libvirt] [PATCH][libvirt-glib] glib-events: Allow zero timeouts for timer
by Michal Privoznik 01 Jun '12

01 Jun '12

In libvirt, it's perfectly possible and widely used to have disabled timers (timeout=-1) and fire them up 'randomly' with timeout=0. However, with current mapping into glib mainloop it's not possible and causing troubles. --- libvirt-glib/libvirt-glib-event.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/libvirt-glib/libvirt-glib-event.c b/libvirt-glib/libvirt-glib-event.c index 94f4de8..c3eb3c8 100644 --- a/libvirt-glib/libvirt-glib-event.c +++ b/libvirt-glib/libvirt-glib-event.c @@ -384,7 +384,7 @@ gvir_event_timeout_update(int timer, if (interval >= 0) { if (data->source) - goto cleanup; + g_source_remove(data->source); data->interval = interval; data->source = g_timeout_add(data->interval, -- 1.7.8.5

[libvirt] Authentication
by Jagannath Timma 31 May '12

31 May '12

Are there any plans to add support for the default authentication method of the server? """ http://libvirt.org/drvhyperv.html Authentication In order to perform any useful operation the driver needs to log into the Hyper-V server. Therefore, only virConnectOpenAuth can be used to connect to an Hyper-V server, virConnectOpen and virConnectOpenReadOnly don't work. To log into an Hyper-V server the driver will request credentials using the callback passed to the virConnectOpenAuth function. The driver passes the hostname as challenge parameter to the callback. Note: Currently only Basic authentication is supported by libvirt. This method is disabled by default on the Hyper-V server and can be enabled via the WinRM commandline tool. "" Regards, Jagannath

[libvirt] [PATCH] SNMP: include inactive domains in guest table
by Jonathan Daugherty 31 May '12

31 May '12

Hi, I've written a patch to include inactive domains in the guest table available via the libvirt-snmp subagent. This makes it possible to start domains via SNMP (a state transition which AFAICT was previously impossible, because inactive domains never appeared in the SNMP result). The code now collects the IDs of running domains along with the names of declared (but not running) domains and normalizes them into a list of domain pointers, which is then processed by the preexisting SNMP container row allocation code. The change was fairly straightforward, but certainly there might be Good Reasons it wasn't already implemented. As part of this change, the other (noteworthy) change I made was to move calls to virDomainFree() to the end of libvirtSnmpLoadGuests() since I have to free all of the used domain pointers there anyway. Some other issues which may need to be addressed: - This will be a breaking change for anyone who assumes that the old behavior is still in place (i.e., that the guest table only includes non-shutdown domains). However, it might not be *that* bad because the domain rows already included a 'state' that one could already filter on. - I don't know if there exists other code in libvirt-snmp that assumes inactive domains can't appear in the table. - I have not tested the inactive -> active state transition (because I don't want to enable writable SNMP OIDs on my server). Please let me know if there is anything further I need to do to make the patch acceptable. Thanks for libvirt-snmp! -- Jonathan Daugherty Software Engineer Galois, Inc.
