[libvirt] [PATCH] domMemoryStats / qemu: Fix parsing of unknown stats
by Adam Litke 21 Jan '10

21 Jan '10

Fix a small problem with the qemu memory stats parsing algorithm. If qemu reports a stat that libvirt does not recognize, skip past it so parsing can continue. This corrects a potential infinite loop in the parsing code that can only be triggered if new statistics are added to qemu.

[libvirt] [PATCH] Fix uses of virFileMakePath.
by Laine Stump 21 Jan '10

21 Jan '10

When I modified the use of virFileMakePath in my own code, I noticed that it was checking for a return < 0 to indicate error, but I had seen in virFileMakePath that it returns 0 for success, or the value of errno on failure, and errno is usually (always?) >=0. Seeing incorrect usage in one place, I investigated and found several others. --- src/lxc/lxc_container.c | 10 +++++----- src/lxc/lxc_controller.c | 2 +- src/lxc/lxc_driver.c | 2 +- src/network/bridge_driver.c | 4 ++-- src/qemu/qemu_driver.c | 8 ++++---- src/uml/uml_driver.c | 4 ++-- 6 files changed, 15 insertions(+), 15 deletions(-) diff --git a/src/lxc/lxc_container.c b/src/lxc/lxc_container.c index 023d553..539a1f4 100644 --- a/src/lxc/lxc_container.c +++ b/src/lxc/lxc_container.c @@ -317,7 +317,7 @@ static int lxcContainerPivotRoot(virDomainFSDefPtr root) goto err;

[libvirt] [PATCH 0/4] Take 3 - Patchset to avoid uid problems in volume creation
by Laine Stump 21 Jan '10

21 Jan '10

The last iteration of this work (which is now completely obsoleted) is at https://www.redhat.com/archives/libvir-list/2010-January/msg00302.html These patches are intended in particular to deal with problems creating storage volumes on pools that are located on root-squashing NFS servers, but hopefully they are overall just "a good thing" and will solve other as-yet-unencountered/unreported problems. Differences from previous version of the patches: 1) For completeness, chmod is done inside virFileCreate and virDirCreate as well as setting uid and gid. 2) Both of those functions now take an additional flag - VIR_FILE_CREATE_ALLOW_EXIST, which does exactly what you'd think. 3) I now always attempt to set uid/gid correctly, even if not running as root (per Serge Hallyn's suggestions during the last go around) 4) I've added a patch that uses similar logic to get the uid/gid/mode of the directories for newly created pools correct as well. (Previously, we'd been ignoring the permission bits of pool definition xml).

[libvirt] [PATCH] domain_conf.c: avoid a leak and the need for "cleanup:" block
by Jim Meyering 20 Jan '10

20 Jan '10

This avoids a leak and the need for a "cleanup:" block, along with its three goto statements. While often I prefer to write functions with a single return point, this one no longer has the need, now that "addr" is freed immediately after allocation. Adding the semicolon in the "case..." stmt may look odd. It's there because the first stmt is the declaration of "port". If you'd prefer, an alternative is to put the contents of that case inside a {...} block. >From dc879b00ccf6cc451b95ca3712e647605579ee0b Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Wed, 20 Jan 2010 19:27:43 +0100 Subject: [PATCH] domain_conf.c: avoid a leak and the need for "cleanup:" block * src/conf/domain_conf.c (virDomainChrDefFormat): Plug a leak on an error path, and at the same time, eliminate the need for a "cleanup:" block.

[libvirt] [PATCH] Libvirt Snapshot API
by Philip Jameson 20 Jan '10

20 Jan '10

A little while ago I submitted a patch to add a snapshot API, but I was informed that it got somewhat lost in the list. I have attached a patch that implements this API at least for the qemu driver, and it also added another function for screenshots, just because it usually is nice to get a view of the screen with the snapshot. The snapshot functions just take names, as I figure it should be up to libvirt to figure out where the snapshots go. e.g. for qemu, they just get stored with the drive using qemu's built in facilities. If someone were using LVM, then that could be managed by libvirt, just like it does for qemu monitors and such. The 'list snapshots' just returns a list of names for now, as that's all I needed, but I think it would probably be best to add a struct that would be name/time. I don't know if it's of any use at the moment, but I needed these functions implemented, so I figured I'd at least submit my changes Philip Jameson

[libvirt] XML for the "boot=on" option
by Shi Jin 20 Jan '10

20 Jan '10

Hi, there, In order to install windows 2008 using the virtio driver, I had to modify the KVM command to include the boot=on option like: -drive file=<path>/virtioWin08.raw,if=virtio,index=0,boot=on However, I haven't been able to find a corresponding libvirt XML element that can enable this "boot=on" option. Is there a way to do this? Thanks a lot. -- Shi Jin, PhD

[libvirt] [PATCH] Fix QEMU driver custom domain status XML extensions
by Daniel P. Berrange 20 Jan '10

Invoking the virConnectGetCapabilities() method causes the QEMU driver to rebuild its internal capabilities object. Unfortunately it was forgetting to register the custom domain status XML hooks again. To avoid this kind of error in the future, the code which builds capabilities is refactored into one single method, which can be called from all locations, ensuring reliable rebuilds. * src/qemu/qemu_driver.c: Fix rebuilding of capabilities XML and guarentee it is always consistent --- src/qemu/qemu_driver.c | 110 +++++++++++++++++++++++------------------------- 1 files changed, 53 insertions(+), 57 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 2d80774..9a3ddfb 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -892,34 +892,6 @@ qemuReconnectDomains(struct qemud_driver *driver) static int -qemudSecurityCapsInit(virSecurityDriverPtr secdrv, - virCapsPtr caps) -{ - const char *doi, *model; - - doi = virSecurityDriverGetDOI(secdrv); - model = virSecurityDriverGetModel(secdrv); - - caps->host.secModel.model = strdup(model); - if (!caps->host.secModel.model) { - virReportOOMError(NULL); - return -1; - } - - caps->host.secModel.doi = strdup(doi); - if (!caps->host.secModel.doi) { - virReportOOMError(NULL); - return -1; - } - - VIR_DEBUG("Initialized caps for security driver \"%s\" with " - "DOI \"%s\"", model, doi); - - return 0; -} - - -static int qemudSecurityInit(struct qemud_driver *qemud_drv) { int ret; @@ -940,15 +912,52 @@ qemudSecurityInit(struct qemud_driver *qemud_drv) qemud_drv->securityDriver = security_drv; VIR_INFO("Initialized security driver %s", security_drv->name); - - /* - * Add security policy host caps now that the security driver is - * initialized. - */ - return qemudSecurityCapsInit(security_drv, qemud_drv->caps); + return 0; } +static virCapsPtr +qemuCreateCapabilities(virCapsPtr oldcaps, + virSecurityDriverPtr secDriver) +{ + virCapsPtr caps; + + /* Basic host arch / guest machine capabilities */ + if (!(caps = qemudCapsInit(oldcaps))) { + virReportOOMError(NULL); + return NULL; + } + + /* Domain XML parser hooks */ + caps->privateDataAllocFunc = qemuDomainObjPrivateAlloc; + caps->privateDataFreeFunc = qemuDomainObjPrivateFree; + caps->privateDataXMLFormat = qemuDomainObjPrivateXMLFormat; + caps->privateDataXMLParse = qemuDomainObjPrivateXMLParse; + + + /* Security driver data */ + if (secDriver) { + const char *doi, *model; + + doi = virSecurityDriverGetDOI(secDriver); + model = virSecurityDriverGetModel(secDriver); + + if (!(caps->host.secModel.model = strdup(model))) + goto no_memory; + if (!(caps->host.secModel.doi = strdup(doi))) + goto no_memory; + + VIR_DEBUG("Initialized caps for security driver \"%s\" with " + "DOI \"%s\"", model, doi); + } + + return caps; + +no_memory: + virReportOOMError(NULL); + virCapabilitiesFree(caps); + return NULL; +} /** * qemudStartup: @@ -1074,13 +1083,12 @@ qemudStartup(int privileged) { virStrerror(-rc, buf, sizeof(buf))); } - if ((qemu_driver->caps = qemudCapsInit(NULL)) == NULL) - goto out_of_memory; + if (qemudSecurityInit(qemu_driver) < 0) + goto error; - qemu_driver->caps->privateDataAllocFunc = qemuDomainObjPrivateAlloc; - qemu_driver->caps->privateDataFreeFunc = qemuDomainObjPrivateFree; - qemu_driver->caps->privateDataXMLFormat = qemuDomainObjPrivateXMLFormat; - qemu_driver->caps->privateDataXMLParse = qemuDomainObjPrivateXMLParse; + if ((qemu_driver->caps = qemuCreateCapabilities(NULL, + qemu_driver->securityDriver)) == NULL) + goto error; if ((qemu_driver->activePciHostdevs = pciDeviceListNew(NULL)) == NULL) goto error; @@ -1104,10 +1112,6 @@ qemudStartup(int privileged) { } } - if (qemudSecurityInit(qemu_driver) < 0) { - goto error; - } - /* If hugetlbfs is present, then we need to create a sub-directory within * it, since we can't assume the root mount point has permissions that * will let our spawned QEMU instances use it. @@ -3255,15 +3259,12 @@ static char *qemudGetCapabilities(virConnectPtr conn) { char *xml = NULL; qemuDriverLock(driver); - if ((caps = qemudCapsInit(qemu_driver->caps)) == NULL) - goto no_memory; - caps->privateDataAllocFunc = qemuDomainObjPrivateAlloc; - caps->privateDataFreeFunc = qemuDomainObjPrivateFree; - - if (qemu_driver->securityDriver && - qemudSecurityCapsInit(qemu_driver->securityDriver, caps) < 0) - goto no_memory; + if ((caps = qemuCreateCapabilities(qemu_driver->caps, + qemu_driver->securityDriver)) == NULL) { + virCapabilitiesFree(caps); + goto cleanup; + } virCapabilitiesFree(qemu_driver->caps); qemu_driver->caps = caps; @@ -3275,11 +3276,6 @@ cleanup: qemuDriverUnlock(driver); return xml; - -no_memory: - virCapabilitiesFree(caps); - virReportOOMError(conn); - goto cleanup; } -- 1.6.5.2

[libvirt] Website contains outdated information about remote limitations
by Matthias Bolte 20 Jan '10

20 Jan '10

http://www.libvirt.org/remote.html#Remote_limitations says: Limitations * Remote storage: To be fully useful, particularly for creating new domains, it should be possible to enumerate and provision storage on the remote machine. This is currently in the design phase. * Migration: We expect libvirt will support migration, and obviously remote support is what makes migration worthwhile. This is also in the design phase. Issues to discuss include which path the migration data should follow (eg. client to client direct, or client to server to client) and security. IMHO this is outdated information, because libvirt supports both features now. So both should be removed from the website as they could misinform newbies. Matthias

[libvirt] [PATCH 0/4] Update interface xml to match netcf 0.1.5
by Laine Stump 20 Jan '10

20 Jan '10

The first two patches make minor additions to the parsing/formatting. The 3rd is a bit more intrusive, as it switches from using virInterfaceBareDef for subordinate interfaces to recursively using a full virInterfaceDef (but with guaranteed closure due to limiting the type of subordinate interface allowed based on parent interface). The final patch updates the RNG and test files accordingly.

[libvirt] hvm/x86_64 combination not allowed
by Steve Brown 20 Jan '10

20 Jan '10

I have a VM that I am able to run using qemu form a command prompt with no problems. I want to run it from within libvirt, so I converted my qemu command to XML using 'virsh domxml-from-native ...' My problem is that my libvirt does not seem to support the x86_64 architecture, so when I try to launch the VM, the kernel won't built since it was installed on x86_64. My os container is as follows (as imported by virsh): <os> <type arch='i686' machine='pc-0.11'>hvm</type> <boot dev='hd'/> </os> However, when I try to change it to this: <os> <type arch='x86_64'>hvm</type> <boot dev='hd'/> </os> I get the following message: error: internal error os type 'hvm' & arch 'x86_64' combination is not supported I've searched for a proper command line switch to build this option into libvirt, but I have not had any success. So how do I get libvirt to support the x86_64 arch?

[libvirt] [PATCH] logging: confirm that we want to ignore a write error
by Jim Meyering 19 Jan '10

19 Jan '10

Ignoring a write failure is a big deal, so when you do that deliberately, it's worth marking in such a way that code analyzers don't report a false positive. Until a year or so ago, people thought using (void) would be enough. But newer gcc warns in spite of that (for functions marked with the warn_unused_result attribute), so now we use the ignore_value function from gnulib. A coverity warning prompted the change below, but if we declare saferead with the warn_unused_result attribute, gcc would, too. >From 62d2c7f69608407afa9a4bf38f0d29ea3eec88f5 Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Mon, 18 Jan 2010 11:51:01 +0100 Subject: [PATCH] logging: confirm that we want to ignore a write error * src/util/logging.c (virLogMessage): Include "ignore-value.h".

This is a patchset for blocking assignment of PCI devices below non-ACS capable switch. In case user still wants to assign such device even though it might not be safe, she can specify 'relaxed_acs_check = 1' in qemu.conf Special thanks to Chris L. who created a standalone program the PCI check. This code is a port of that check to libvirt. Changes in version 2: - permissive attribute for <hostdev> was removed - new 'relaxed_acs_check' config option in qemu.conf for relaxing the check Jiri Denemark (2): Tests for ACS in PCIe switches Use pciDeviceIsAssignable in qemu driver src/libvirt_private.syms | 1 + src/qemu/libvirtd_qemu.aug | 1 + src/qemu/qemu.conf | 6 ++ src/qemu/qemu_conf.c | 4 + src/qemu/qemu_conf.h | 2 + src/qemu/qemu_driver.c | 6 ++- src/qemu/test_libvirtd_qemu.aug | 6 ++- src/util/pci.c | 151 +++++++++++++++++++++++++++++++++++++++ src/util/pci.h | 4 + 9 files changed, 179 insertions(+), 2 deletions(-)

[libvirt] [PATCH] Make all bitfields unsigned ints to avoid unexpected values in casts
by Daniel P. Berrange 19 Jan '10

19 Jan '10

The 'int virInterfaceIsActive()' method was directly returning the value of the 'int active:1' bitfield in virIntefaceDefPtr. A bitfield with a signed integer, will hold the values 0 and -1, not 0 and +1 as might be expected. This meant that virInterfaceIsActive() was always returning -1 when the interface was active, not +1 & thus all callers thought an error had occurred. To protect against this kind of mistake again, change all bitfields to be unsigned ints * daemon/libvirtd.h, src/conf/domain_conf.h, src/conf/interface_conf.h, src/conf/network_conf.h: Change bitfields to unsigned int. --- daemon/libvirtd.h | 14 +++++++------- src/conf/domain_conf.h | 14 +++++++------- src/conf/interface_conf.h | 2 +- src/conf/network_conf.h | 2 +- 4 files changed, 16 insertions(+), 16 deletions(-) diff --git a/daemon/libvirtd.h b/daemon/libvirtd.h index 2f647f3..a7591fc 100644 --- a/daemon/libvirtd.h +++ b/daemon/libvirtd.h @@ -175,9 +175,9 @@ struct qemud_client { int fd; int watch; - int readonly:1; - int closing:1; - int domain_events_registered:1; + unsigned int readonly :1; + unsigned int closing :1; + unsigned int domain_events_registered :1; struct sockaddr_storage addr; socklen_t addrlen; @@ -185,7 +185,7 @@ struct qemud_client { int type; /* qemud_sock_type */ gnutls_session_t tlssession; int auth; - int handshake : 1; /* If we're in progress for TLS handshake */ + unsigned int handshake :1; /* If we're in progress for TLS handshake */ #if HAVE_SASL sasl_conn_t *saslconn; int saslSSF; @@ -244,9 +244,9 @@ struct qemud_socket { struct qemud_worker { pthread_t thread; - int hasThread :1; - int processingCall :1; - int quitRequest : 1; + unsigned int hasThread :1; + unsigned int processingCall :1; + unsigned int quitRequest :1; /* back-pointer to our server */ struct qemud_server *server; diff --git a/src/conf/domain_conf.h b/src/conf/domain_conf.h index 1413273..7be090d 100644 --- a/src/conf/domain_conf.h +++ b/src/conf/domain_conf.h @@ -400,8 +400,8 @@ enum virDomainVideoType { typedef struct _virDomainVideoAccelDef virDomainVideoAccelDef; typedef virDomainVideoAccelDef *virDomainVideoAccelDefPtr; struct _virDomainVideoAccelDef { - int support3d : 1; - int support2d : 1; + unsigned int support3d :1; + unsigned int support2d :1; }; @@ -432,7 +432,7 @@ struct _virDomainGraphicsDef { union { struct { int port; - int autoport : 1; + unsigned int autoport :1; char *listenAddr; char *keymap; char *passwd; @@ -445,13 +445,13 @@ struct _virDomainGraphicsDef { struct { int port; char *listenAddr; - int autoport : 1; - int replaceUser : 1; - int multiUser : 1; + unsigned int autoport :1; + unsigned int replaceUser :1; + unsigned int multiUser :1; } rdp; struct { char *display; - int fullscreen : 1; + unsigned int fullscreen :1; } desktop; } data; }; diff --git a/src/conf/interface_conf.h b/src/conf/interface_conf.h index 2683eee..5b201d3 100644 --- a/src/conf/interface_conf.h +++ b/src/conf/interface_conf.h @@ -170,7 +170,7 @@ typedef virInterfaceObj *virInterfaceObjPtr; struct _virInterfaceObj { virMutex lock; - int active:1; /* 1 if interface is active (up) */ + unsigned int active:1; /* 1 if interface is active (up) */ virInterfaceDefPtr def; /* The interface definition */ }; diff --git a/src/conf/network_conf.h b/src/conf/network_conf.h index 0214d1a..9e50659 100644 --- a/src/conf/network_conf.h +++ b/src/conf/network_conf.h @@ -65,7 +65,7 @@ struct _virNetworkDef { char *bridge; /* Name of bridge device */ char *domain; unsigned long delay; /* Bridge forward delay (ms) */ - int stp : 1; /* Spanning tree protocol */ + unsigned int stp :1; /* Spanning tree protocol */ int forwardType; /* One of virNetworkForwardType constants */ char *forwardDev; /* Destination device for forwarding */ -- 1.6.5.2

[libvirt] [PATCH] Take disabled/forced CPU features into account
by Jiri Denemark 19 Jan '10

19 Jan '10

When comparing x86 CPUs, features with 'disabled' policy were mistakenly required to be supported by the host CPU. Likewise, features with 'force' policy which were supported by host CPU would make CPUs incompatible if 'strict' match was used by guest CPU. This patch fixes both issues.

[libvirt] [PATCH] Enhance qemuParseCommandLineKeywords
by Jiri Denemark 19 Jan '10

19 Jan '10

Current version expects name=value,... list and when an incorrect string such as "a,b,c=d" would be parsed as "a,b,c" keyword with "d" value without reporting any error, which is probably not the expected behavior. This patch adds an extra argument called allowEmptyValue, which if non-zero will permit keywords with no value; "a,b=c,,d=" will be parsed as follows: keyword value "a" NULL "b" "c" "" NULL "d" "" In case allowEmptyValue is zero, the string is required to contain name=value pairs only; retvalues is guaranteed to contain non-NULL pointers. Now, "a,b,c=d" will result in an error.

[libvirt] Cannot use console with 0.7.5, error: internal error no assigned pty for device serial0
by Marc Haber 18 Jan '10

18 Jan '10

[my apologies for this re-post. I stupidly managed to hide the first instance of this mail away in an unrelated patch-thread and am thus afraid that the people who could have answered didn't see it] Hi, I have one test host running Debian unstable (kernel 2.6.32.3), and I would like to virtualize on it using KVM and virsh. Debian unstable has libvirt 0.7.5. On this host, I cannot start any KVM domain using console with these XML parts: <serial type='pty'> <target port='0'/> </serial> <console type='pty'> <target port='0'/> </console> When I try virsh start $domain, I get the error message: error: internal error no assigned pty for device serial0 When I remove the serial and console stanza, the machine starts up. This is the configuration documented everywhere. At first, I suspected a change in the configuration syntax and filed Debian bug #565145, But on the #virt IRC channel, people suggested that there was a change in libvirt parsing KVM's output, which may be a genuine bug breaking the console. Is this already a known issue? Can I do anything to help debugging?

[libvirt] [PATCH 00/34] Add device addressing and disk controller support
by Daniel P. Berrange 18 Jan '10

18 Jan '10

This series is a merge of two previous series I posted http://www.redhat.com/archives/libvir-list/2009-December/msg00232.html http://www.redhat.com/archives/libvir-list/2009-December/msg00392.html It accomplishes quite a lot of things, having major impact on the QEMU driver, hopefully all in a postive way :-) In particular it does * Add standard XML syntax for addressing of PCI devices, and disk drives * Add support for disk controllers as a managed device in XML * Add support for disk controller hotplug/unplug * Convert everything over to use QEMU's -device flag where available * Add PCI addressing when using -device * Introduce a way to give every device a unique 'alias' name in the XML format I can't promise it works perfectly, but i've done quite alot of positive testing with it now & believe all the back comptability stuff is working right.

When virStorageBackendProbeTarget fails, it returns -1 or -2. The two uses below obviously intended to handle those cases differently, but due to a wrong comparison, they always treated a "real" (e.g., open) failure (-1) just like an ignorable "wrong file type" failure (-2). FYI, coverity reported that the "goto cleanup" statement was unreachable, which was true in each case, but hardly the real problem. >From c9ba79daf124afbab351741192bbaf7110a199dd Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Mon, 18 Jan 2010 10:34:53 +0100 Subject: [PATCH] storage_backend_fs.c: do not ignore probe failure * src/storage/storage_backend_fs.c (virStorageBackendFileSystemRefresh): Correct two error-handling bugs.

[libvirt] [PATCH] secret_driver.c: remove dead cleanup code
by Jim Meyering 18 Jan '10

18 Jan '10

Here's another example of appropriate use of assert. The while loop removed below is currently guaranteed never to be executed, since "list" is always NULL at that point. However, you can argue that simply removing the loop is a little risky: what if someone changes things to "goto cleanup" before "list" reaches the final NULL? That's why I added the assertion: to catch the potential (albeit unlikely) future coding error. It would be a shame to include "real" run-time code to detect a situation like that that will probably never arise. And if you do, technically you'd have to document that the function would return some sort of error code if a developer changes its guts in a way that violates this invariant. That would be nonsensical. >From 6baa2b0b8f9963fa60ff0946afcefd57586e2720 Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Mon, 18 Jan 2010 10:46:57 +0100 Subject: [PATCH] secret_driver.c: remove dead cleanup code * src/secret/secret_driver.c (loadSecrets): Remove dead code after "cleanup:".

[libvirt] [PATCH] Use closest CPU model when decoding from CPUID
by Jiri Denemark 18 Jan '10

18 Jan '10

Current implementation of x86Decode() used for CPUID -> model+features translation does not always select the closest CPU model. When walking through all models from cpu_map.xml the function considers a new candidate as a better choice than a previously selected candidate only if the new one is a superset of the old one. In case the new candidate is closer to host CPU but lacks some feature comparing to the old candidate, the function does not choose well. This patch changes the algorithm so that the closest model is always selected. That is, the model which requires the lowest number of additional features to describe host CPU.

[libvirt] [PATCH 1/2] Standardise ./configure --help options reporting.
by Diego Elio Pettenò 18 Jan '10

18 Jan '10

Always use AC_HELP_STRING for the help text for options at ./configure, so that the output is properly aligned. Use proper quadrigraphs for outputting the brackets. Always use autoconf-style [default=$foo] output to state the default, both where it was stated before and where it wasn't. This time, include Matthias Bolte notes regarding defaults, and removing PFX specification from phyp. --- configure.in | 100 +++++++++++++++++++++++++++++----------------------------- 1 files changed, 50 insertions(+), 50 deletions(-) diff --git a/configure.in b/configure.in index 012a96f..447d57e 100644 --- a/configure.in +++ b/configure.in @@ -205,33 +205,33 @@ fi dnl Allow to build without Xen, QEMU/KVM, test or remote driver AC_ARG_WITH([xen], -[ --with-xen add XEN support (on)],[],[with_xen=yes]) + AC_HELP_STRING([--with-xen], [add XEN support @<:@default=yes@:>@]),[],[with_xen=yes]) AC_ARG_WITH([xen-inotify], -[ --with-xen-inotify add XEN inotify support (on)],[],[with_xen_inotify=check]) + AC_HELP_STRING([--with-xen-inotify], [add XEN inotify support @<:@default=check@:>@]),[],[with_xen_inotify=check]) AC_ARG_WITH([qemu], -[ --with-qemu add QEMU/KVM support (on)],[],[with_qemu=yes]) + AC_HELP_STRING([--with-qemu], [add QEMU/KVM support @<:@default=yes@:>@]),[],[with_qemu=yes]) AC_ARG_WITH([uml], -[ --with-uml add UML support (on)],[],[with_uml=check]) + AC_HELP_STRING([--with-uml], [add UML support @<:@default=check@:>@]),[],[with_uml=check]) AC_ARG_WITH([openvz], -[ --with-openvz add OpenVZ support (on)],[],[with_openvz=yes]) + AC_HELP_STRING([--with-openvz], [add OpenVZ support @<:@default=yes@:>@]),[],[with_openvz=yes]) AC_ARG_WITH([libssh2], -[ --with-libssh2=[PFX] libssh2 location],[],[with_libssh2=yes]) + AC_HELP_STRING([--with-libssh2=@<:@PFX@:>@], [libssh2 location @<:@default=/usr/local/lib@:>@]),[],[with_libssh2=yes]) AC_ARG_WITH([phyp], -[ --with-phyp=[PFX] add PHYP support (on)],[],[with_phyp=check]) + AC_HELP_STRING([--with-phyp], [add PHYP support @<:@default=check@:>@]),[],[with_phyp=check]) AC_ARG_WITH([vbox], -[ --with-vbox add VirtualBox support (on)],[],[with_vbox=yes]) + AC_HELP_STRING([--with-vbox], [add VirtualBox support @<:@default=yes@:>@]),[],[with_vbox=yes]) AC_ARG_WITH([lxc], -[ --with-lxc add Linux Container support (on)],[],[with_lxc=check]) + AC_HELP_STRING([--with-lxc], [add Linux Container support @<:@default=check@:>@]),[],[with_lxc=check]) AC_ARG_WITH([one], -[ --with-one add ONE support (on)],[],[with_one=check]) + AC_HELP_STRING([--with-one], [add ONE support @<:@default=check@:>@]),[],[with_one=check]) AC_ARG_WITH([esx], -[ --with-esx add ESX support (on)],[],[with_esx=check]) + AC_HELP_STRING([--with-esx], [add ESX support @<:@default=check@:>@]),[],[with_esx=check]) AC_ARG_WITH([test], -[ --with-test add test driver support (on)],[],[with_test=yes]) + AC_HELP_STRING([--with-test], [add test driver support @<:@default=yes@:>@]),[],[with_test=yes]) AC_ARG_WITH([remote], -[ --with-remote add remote driver support (on)],[],[with_remote=yes]) + AC_HELP_STRING([--with-remote], [add remote driver support @<:@default=yes@:>@]),[],[with_remote=yes]) AC_ARG_WITH([libvirtd], -[ --with-libvirtd add libvirtd support (on)],[],[with_libvirtd=yes]) + AC_HELP_STRING([--with-libvirtd], [add libvirtd support @<:@default=yes@:>@]),[],[with_libvirtd=yes]) dnl dnl specific tests to setup DV devel environments with debug etc ... @@ -245,8 +245,8 @@ AC_SUBST([STATIC_BINARIES]) dnl --enable-debug=(yes|no) AC_ARG_ENABLE([debug], - [AC_HELP_STRING([--enable-debug=no/yes], - [enable debugging output])],[],[enable_debug=yes]) + [AC_HELP_STRING([--enable-debug=@<:@no|yes@:>@], + [enable debugging output @<:@default=yes@:>@])],[],[enable_debug=yes]) AM_CONDITIONAL([ENABLE_DEBUG], test x"$enable_debug" = x"yes") if test x"$enable_debug" = x"yes";

[libvirt] [PATCH 0/4] A bit of configure clear-up
by Diego Elio Pettenò 18 Jan '10

18 Jan '10

Since on the whole it seems like the configure could see some cleanup, as it seem to use lots of older constructs and repeated code, I tried doing some basic cleaning. My changes also require autoconf-2.63… it could be something older as well, but 2.63 is new enough I'd say. If nobody has reasons for 2.59 compatibility to stick around, it would probably improve a lot. HTH! -- Diego

[libvirt] [PATCH] qemu: Use log output for pty assignment if 'info chardev' is unavailable
by Matthias Bolte 18 Jan '10

18 Jan '10

qemudFindCharDevicePTYsMonitor reports an error if 'info chardev' didn't provide information for a requested device, even if the log output parsing had found the pty path for that device. This makes pty assignment fail for older QEMU/KVM versions. For example KVM 72 on Debian doesn't support 'info chardev', so qemuMonitorTextGetPtyPaths cannot parse any useful information and the hash for device-id-to-pty-path mapping stays empty. Make qemudFindCharDevicePTYsMonitor report an error only if the log output parsing and the 'info chardev' parsing failed to provide the pty path. --- src/qemu/qemu_driver.c | 14 +++++++++++--- 1 files changed, 11 insertions(+), 3 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index d13119f..783d9fc 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -1428,9 +1428,17 @@ qemudFindCharDevicePTYsMonitor(virConnectPtr conn, \ const char *path = (const char *) virHashLookup(paths, id); \ if (path == NULL) { \ - qemudReportError(conn, NULL, NULL, VIR_ERR_INTERNAL_ERROR,\ - _("no assigned pty for device %s"), id); \ - return -1; \ + if (chr->data.file.path == NULL) { \ + /* neither the log output nor 'info chardev' had a */ \ + /* pty path for this chardev, report an error */ \ + qemudReportError(conn, NULL, NULL, VIR_ERR_INTERNAL_ERROR, \ + _("no assigned pty for device %s"), id); \ + return -1; \ + } else { \ + /* 'info chardev' had no pty path for this chardev, */\ + /* but the log output had, so we're fine */ \ + continue; \ + } \ } \ \ VIR_FREE(chr->data.file.path); \ -- 1.6.3.3

[libvirt] LVM storage pool with existing mirrored volumes
by Ben Roberts 17 Jan '10

17 Jan '10

Hi, I tried to setup a lvm-backed storage pool, reusing an existing volume group which already contains a handful of mirrored logical volumes. For reference, I am using lvm 2.02.56-r3, qemu-kvm 0.12.1.2 and libvirt 0.7.5 on an up-to-date ~amd64 gentoo system. The first issue I encountered is when trying to activate the storage pool, the process fails with "internal error lvs command failed". This appears to be because the output of lvs is slightly different when using mirrored lvs, and is breaking the parser: /sbin/lvs --separator , --noheadings --units b --unbuffered --nosuffix --options lv_name,origin,uuid,devices,seg_size,vg_extent_size bigpool vms,,0PzrRS-8Ljs-SUq0-ywFH-BI3d-RI0V-aibupu,vms_mimage_0(0),vms_mimage_1(0),107374182400,4194304 backups,,Snk2NL-oJe3-GpTL-Qihs-ZjjG-xPyj-ufmwCp,backups_mimage_0(0),backups_mimage_1(0),214748364800,4194304 The device column of output would normally contain something like "/dev/sda(1234)", but here contains "vms_mimage_0(0),vms_mimage_1(0). This is causing the parser to misinterpret the output, and it believes the lv name to be suffixed with a trailing comma, eg "vms,". When trying to access "/dev/bigpool/vms,", the command errors with File or Directory not Found. When adding the --all parameter to lvs, the hidden mirroring lvs are visible, and these have the expected structure: vms,,0PzrRS-8Ljs-SUq0-ywFH-BI3d-RI0V-aibupu,vms_mimage_0(0),vms_mimage_1(0),107374182400,4194304 [vms_mlog],,vnOzg8-ynKc-kM8F-RKdM-xXC0-PJlG-qcgmFh,/dev/sda2(0),4194304,4194304 [vms_mimage_0],,2pXjHt-aARa-FOO7-ZL6N-ahpu-ebdr-P6Qxj3,/dev/sdb1(0),107374182400,4194304 [vms_mimage_1],,ITd8CT-JpKi-Y2a6-a4jc-2yDa-9VmG-gWgRd8,/dev/sdc1(51200),107374182400,4194304 Presumably, without the --all parameter and listing the internal mirroring volumes, libvirt will miscalculate sizes of LVs in the VG. This bug appears to prevent the use of any volume group which contains one or more mirrored logical volumes as a backend storage pool. -- Ben Roberts Computer Science MEng, Part IV Electronics and Computer Science, University of Southampton

[libvirt] Visualizing the first four years of libvirt development
by Daniel P. Berrange 17 Jan '10

>From the 'just a bit of fun' category, I've published a couple of videos visualizing the first four years of libvirt development The first, created using 'gource' [1]: http://www.youtube.com/watch?v=sEN4gxmCOuw The second, creating using 'code_swarm' [2]: http://www.youtube.com/watch?v=ptvATk1xPIw In both of these you can clearly tell when we started using GIT, since the improved patch author attribution results in an explosion of participants in the visualizations :-) Of course some of that is also due to the expanding libvirt development from the introduction of new drivers like VMWare and VirtualBox...

[libvirt] [PATCH] gnulib added a new syntax-check test: use $(VAR), not @VAR@
by Jim Meyering 15 Jan '10

15 Jan '10

Updating to newer gnulib also pulled in a new sytnax-check test that evoked new warnings. No big deal, but I addressed them. The only trick was to see that the warnings about @SCHEMADIR@ and @SYSCONFDIR@ were false positives. To allow them, I defined the variable in cfg.mk.

[libvirt] Using ESX domain XML for V2V
by Matthew Booth 15 Jan '10

15 Jan '10

I'm trying to use the ESX driver to extract metadata from ESX in an easily digestible form for driving V2V. I've noticed the domain XML seems to be missing a few bits: <features/> <graphics/> <input/> <serial/> and <console/> are also missing, but that could well be because they aren't present. Is this intentional? Should I be assuming some of the above because it's ESX, or is this an omission?

[libvirt] newer gnulib: requires several header-include fixes
by Jim Meyering 15 Jan '10

15 Jan '10

A week or two ago, upstream gnulib was fixed to be more namespace friendly in how it creates replacement headers. For some of its replacements (e.g., <stdio.h>, used via gnulib/lib/stdio.h), it would unnecessarily include another header, e.g., <stdlib.h>. That would make it so that an application using gnulib's <stdio.h> could think it's fine *not* to include stdlib.h, even though it uses a function like exit whose declaration usually requires an explicit inclusion of <stdlib.h>. [the example above is made up -- in reality it was more subtle] Well, now, those excess inclusions have been removed, and when I upgraded libvirt to use the latest gnulib, I saw many compilation failures due to missing #include directives. This series fixes the problems, then adds a change-set to update to the latest gnulib. Here are the one-line summaries: util.c: include required header, no longer masked by gnulib cpu_x86_data.h: include required header vbox: include required headers esx_vi_types.c: include required headers storage_backend.h: include required headers build: update gnulib submodule to latest >From ed2e5140a5a5529ca19e730d061f6d5b3872bb7f Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Fri, 15 Jan 2010 10:31:23 +0100 Subject: [PATCH 1/6] util.c: include required header, no longer masked by gnulib Until recently, some gnulib-generated replacement headers included *other* headers that were not strictly necessary, thus masking the need in this file for an explicit <stdlib.h>. * src/util/util.c: Include <stdlib.h> for declarations of e.g., strtol, random_r, getenv, etc. --- src/util/util.c | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) diff --git a/src/util/util.c b/src/util/util.c index 45ca657..67fae00 100644 --- a/src/util/util.c +++ b/src/util/util.c @@ -1,7 +1,7 @@ /* * utils.c: common, generic utility functions * - * Copyright (C) 2006, 2007, 2008, 2009 Red Hat, Inc. + * Copyright (C) 2006-2010 Red Hat, Inc. * Copyright (C) 2006 Daniel P.

[libvirt] [PATCH v2] Implement path lookup for USB by vendor:product
by Cole Robinson 14 Jan '10

14 Jan '10

Based off how QEMU does it, look through /sys/bus/usb/devices/* for matching vendor:product info, and if found, use info from the surrounding files to build the device's /dev/bus/usb path. This fixes USB device assignment by vendor:product when running qemu as non-root (well, it should, but for some reason I couldn't reproduce the failure people are seeing in [1], but it appears to work properly) [1] https://bugzilla.redhat.com/show_bug.cgi?id=542450 v2: Drop 'bus.addr only' checks in security drivers Use various util helpers Signed-off-by: Cole Robinson <crobinso(a)redhat.com> --- po/POTFILES.in | 1 + src/qemu/qemu_driver.c | 9 +-- src/security/security_selinux.c | 25 ++++----- src/security/virt-aa-helper.c | 32 +++++------ src/util/hostusb.c | 110 +++++++++++++++++++++++++++++++++++++- src/util/hostusb.h | 4 +- 6 files changed, 141 insertions(+), 40 deletions(-) diff --git a/po/POTFILES.in b/po/POTFILES.in index c9c78b6..3b82a74 100644 --- a/po/POTFILES.in +++ b/po/POTFILES.in @@ -55,6 +55,7 @@ src/uml/uml_conf.c src/uml/uml_driver.c src/util/bridge.c src/util/conf.c +src/util/hostusb.c src/util/json.c src/util/logging.c src/util/pci.c diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index deb8adc..f03ce91 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -2105,14 +2105,11 @@ static int qemuDomainSetHostdevUSBOwnership(virConnectPtr conn, struct qemuFileOwner owner = { uid, gid }; int ret = -1; - /* XXX what todo for USB devs assigned based on product/vendor ?

[libvirt] attach_device incompatibility between libvirt and qemu 0.12
by Gerhard Stenzel 14 Jan '10

14 Jan '10

Hi, I have a small libvirt-tck test script, in which I create a domain without a NIC, then use attach_device to add a NIC. And then I do a ping test to the domain. This stopped working after updating to latest fedora and libvirt levels. After some hours, I now discovered that downgrading to qemu 0.11 fixes it. So there seems to be some incompatibility with qemu 0.12 and latest libvirt. The expected output with qemu-system-x86-0.11.0-12.fc12.x86_64: /usr/share/libvirt-tck/tests/scripts/network/100-ping-still-working.t .. 1..5 # Trying domain lookup by name ok 1 - the running domain object # Attaching the new interface d0:f:d0:f:2:1 ok 2 - interface has been attached # xml contains mac address element (should be 1) # 1 ok 3 - running domain has an ID > 0 # waiting for guests to boot # PING 192.168.1.101 (192.168.1.101) 56(84) bytes of data. # 64 bytes from 192.168.1.101: icmp_seq=1 ttl=64 time=2.17 ms # 64 bytes from 192.168.1.101: icmp_seq=2 ttl=64 time=0.554 ms # 64 bytes from 192.168.1.101: icmp_seq=3 ttl=64 time=0.510 ms # 64 bytes from 192.168.1.101: icmp_seq=4 ttl=64 time=0.508 ms # 64 bytes from 192.168.1.101: icmp_seq=5 ttl=64 time=0.505 ms # 64 bytes from 192.168.1.101: icmp_seq=6 ttl=64 time=0.673 ms # 64 bytes from 192.168.1.101: icmp_seq=7 ttl=64 time=0.528 ms # 64 bytes from 192.168.1.101: icmp_seq=8 ttl=64 time=0.522 ms # 64 bytes from 192.168.1.101: icmp_seq=9 ttl=64 time=0.506 ms # 64 bytes from 192.168.1.101: icmp_seq=10 ttl=64 time=0.546 ms # # --- 192.168.1.101 ping statistics --- # 10 packets transmitted, 10 received, 0% pacFor the working I see the following lines in the log: ket loss, time 9002ms # rtt min/avg/max/mdev = 0.505/0.703/2.178/0.493 ms ok 4 - ping 192.168.1.101 test # cleaning up # Detaching the 1st interface d0:f:d0:f:2:1 ok 5 - interface has been detached ok All tests successful.

[libvirt] [PATCH] Fix event-test segfault for mixed remote/local driver usage
by Matthias Bolte 14 Jan '10

14 Jan '10

If examples/domain-events/events-c/event-test.c uses a local driver for the hyperviror and a remote driver for storage then the segfault occurs in remoteDomainEventDispatchFunc because conn->privateData is used. The problem is as follows. The doRemoteOpen function registers remoteDomainEventFired as event handle and remoteDomainEventQueueFlush as event timeout. The doRemoteOpen function is used in remoteOpen and remoteOpenSecondaryDriver. So both handlers are registered for all types of remote drivers, but remoteDomainEventQueueFlush always uses conn->privateData. That's wrong when remoteDomainEventQueueFlush is called for any other driver than the hypervisor driver, it should use conn->storagePrivateData for the storage driver for example. In the common case this doesn't result in a segfault because in the common case all drivers for a connection are either all remote or all local and conn->privateData and conn->storagePrivateData are the same. But in the local Xen case ('event-test xen:///' executed in Domain-0, with a libvirtd running in Domain-0) the hypervisor driver is local and the storage driver is remote. This results in a mismatch between conn->privateData and conn->storagePrivateData. Now the call to remoteDomainEventQueueFlush in the context of the storage driver results in a segfault, because it assumes that conn->privateData points to remote driver private data, but it points to Xen driver private data. To fix this, the pointer to the private driver data gets passed as opaque parameter instead of the connection pointer. Because some functions called by the event handler functions need the connection pointer for other purposes than error reporting the connection pointer is passed as member of the private remote driver data struct. Now remoteDomainEventFired and remoteDomainEventQueueFlush have the correct private data pointer for the respective calling context. --- src/remote/remote_driver.c | 16 ++++++++-------- 1 files changed, 8 insertions(+), 8 deletions(-) diff --git a/src/remote/remote_driver.c b/src/remote/remote_driver.c index d6f5fce..582b85c 100644 --- a/src/remote/remote_driver.c +++ b/src/remote/remote_driver.c @@ -152,6 +152,7 @@ struct private_stream_data { struct private_data { virMutex lock; + virConnectPtr conn; int sock; /* Socket. */ int watch; /* File handle watch */ @@ -893,7 +894,7 @@ doRemoteOpen (virConnectPtr conn, if ((priv->watch = virEventAddHandle(priv->sock, VIR_EVENT_HANDLE_READABLE, remoteDomainEventFired, - conn, NULL)) < 0) { + priv, NULL)) < 0) { DEBUG0("virEventAddHandle failed: No addHandleImpl defined."

[libvirt] Set MAC address for host virtual interface?
by Neil Aggarwal 14 Jan '10

14 Jan '10

Hello: Is there a way to set the MAC address for the virtual interface on the host? I have this in my guests's XML file: <interface type='bridge'> <mac address='54:52:00:7d:f8:fc'/> <source bridge='br0'/> <target dev='tkl-joomla'/> </interface> the mac address line controls the guest interface but the host interface seems to get a random MAC address. This is causing a problem for me since I use Cacti to monitor the bandwidth usage of the guest machines. Every time I stop and start a guest, Cacti creates a new interface and I have to reset the graphs to use the new interfaces.

[libvirt] [BUG?] "no domain with matching uuid" error, when vm restarts
by su disheng 14 Jan '10

14 Jan '10

Hi, In the following libvirt API calling sequence, I always get an error "no domain with matching uuid" Connect _conn = new Connect("qemu:///system", false); _conn.domainDefineXML(kvm_guest_xml); Domain dm = _conn.domainLookupByName(kvm_guest_name); dm.create(); /* stop, undefine, and re-start the vm*/ dm.shutdown(); dm.undefine(); dm.domainDefineXML(kvm_guest_xml); /****A****/ Domain dm = _conn.domainLookupByName(kvm_guest_name); dm.create() /********Error!!!!**/ if I close the connection, and re-connect qemu at the end of /****A****/, then everything is OK. From the log, seems that uuid is not updated immediately, for this connection, the uuid is in the stale state? I am using libvirt 0.6.3, if it's a bug, does it fixed in the latest code? or Have I need to close the connection for each vm shutdown/re-define? I am a newbie in this API, any help are appreciated.

[libvirt] [PATCH 0/2] Some new utility functions
by Laine Stump 13 Jan '10

13 Jan '10

I'm planning to use these to fix the problems with creating storage volumes on root-squashing NFS servers, but since they may be of general utility I thought I'd throw them out for comments beforehand - it something different would make them more generally useful, better to change it now than after I've already finished code to use them. My plan is to use virRunWithHook() to call setuid (or possibly some sort of capng calisthenics) prior to execing qemu-img and qcow-create. virFileCreate and virDirCreate will be used when creating raw volumes. I have written test code to verify that virFileCreate works in several different scenarios. Haven't done so with virRun yet, but it's a fairly simple change, just exposing __virExec arguments that were already there. (I'd previously written test code (yes, it worked ;-)) that used a virRun with uid/gid args added on, but have decided against that approach, since this seems more flexible)

[libvirt] VMware vCenter support

Dear List, I find the ESX driver in libvirt quite useful to perform powercycle operations on a VM. However, I need to connect to an ESX server even when the VM is managed on the VMware 4.0 platform. Reading this mail: http://www.mail-archive.com/libvir-list@redhat.com/msg18259.html makes me think that support to connect directly to a vCenter using the scheme vpx:// is not far from becoming a reality. Could you please provide an estimated timeline for this and notes on possible further enhancements in the ESX driver code? Thank you very much in advance.

[libvirt] [PATCH] Fix migration in xend driver
by Jim Fehlig 12 Jan '10

12 Jan '10

Upstream xen has changed parameters to the migration operation several times over the past 18 months. Changeset 17553 removed the resouce parameter, Changesets 17709, 17753, and 20326 added ssl, node, and change_home_server parameters respectively. Fortunately, testing has revealed that xend will fail the operation if a parameter is missing but happily honor it if unknown parameters are provided. Thus all currently supported parameters can be provided, satisfying current xend but not regressing older versions. --- src/xen/xend_internal.c | 14 ++++++++++---- 1 files changed, 10 insertions(+), 4 deletions(-) diff --git a/src/xen/xend_internal.c b/src/xen/xend_internal.c index be033f5..d9bfa15 100644 --- a/src/xen/xend_internal.c +++ b/src/xen/xend_internal.c @@ -4553,15 +4553,21 @@ xenDaemonDomainMigratePerform (virDomainPtr domain, DEBUG("hostname = %s, port = %s", hostname, port); - /* Make the call. */ + /* Make the call. + * NB: xend will fail the operation if any parameters are + * missing but happily accept unknown parameters.

[libvirt] Start external programm on network-setup
by Dominik Bruhn 12 Jan '10

12 Jan '10

Hy, im using libvirt-bin on debian and configured the network of libvirt to be a standalone bridge. Is there a possibility to run a program after the bridge has successfully and completly set up by libvirtd? I would like to restart shorewall (a firewall) when the bridge is set up to activate MASQ and DNAT and other policies which I need. I would also like to start my own configured dnsmasq when the interface is up (can't start it realier because it has to bind to the interface). I hope thats the right place to ask such a question, if not, please direct me. Thanks for the help -- Dominik mailto: dominik(a)dbruhn.de

The following series adds internal APIs that help prevent legitimate errors from being overwritten by other errors (for example in cleanup routines). The majority of this series is a patch from Dan[1] which makes error callbacks explictly triggered when exiting an API call, rather than when an error is raised (I've updated this to cover the current codebase) [1] http://gitorious.org/~berrange/libvirt/staging/commits/error-callbacks Cole Robinson (4): virterror: Add virSetError qemu: migrate: Save MigratePerform error in MigrateFinish. libvirt.c: Preserve MigratePerform failure qemu: Disable errors in qemudShutdownVMDaemon Daniel P.

I'm curious to know why when using the UIR xen:/// multiple myEventAddHandleFunc() calls occurred. Are there and fields I could use to identify and ignore the spurious calls? I'd like to use the event monitoring for several remote Xen hosts. I assume I'll have to modify the code to connect remotely to each host and hope for just one myEventAddHandleFunc() call per host. Thanks for your assistance it's much apprecied, Regards, Pete

[libvirt] [PATCH] remote_driver.c: fix a NULL dereference in remoteDomainEventQueueFlush().
by kakuma 12 Jan '10

12 Jan '10

Hi, all. There is a case of a NULL dereference in function remoteDomainEventQueueFlush() in remote_driver.c In the case of local connection conn->privateData->domainEvents isn't reserved. In this case it will occurs segment fault. (for example examples/domain-events/events-c/event-test.c) I think the following patch will be available. Thanks. --- src/remote/remote_driver.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/src/remote/remote_driver.c b/src/remote/remote_driver.c index d6f5fce..b112fd3 100644 --- a/src/remote/remote_driver.c +++ b/src/remote/remote_driver.c @@ -8709,7 +8709,7 @@ void remoteDomainEventQueueFlush(int timer ATTRIBUTE_UNUSED, void *opaque) { virConnectPtr conn = opaque; - struct private_data *priv = conn->privateData; + struct private_data *priv = conn->networkPrivateData; virDomainEventQueue tempQueue; remoteDriverLock(priv); -- 1.5.6.1 -- kakuma <f-kak(a)ksh.biglobe.ne.jp>

[libvirt] [PATCH] qemu: Fix a memory leak in qemudExtractTTYPath

qemudWaitForMonitor calls qemudReadLogOutput with qemudFindCharDevicePTYs as callback. qemudFindCharDevicePTYs calls qemudExtractTTYPath to assign a string to chr->data.file.path. Afterwards qemudWaitForMonitor may call qemudFindCharDevicePTYsMonitor that overwrites chr->data.file.path without freeing the old value. This results in leaking the memory allocated by qemudExtractTTYPath.

To make sure I understand the API. If I have a domain defined, but not started.. it will show up in the list returned by: virConnectListDefinedDomains but not in the list virConnectListDomains Conversely, if it is started... it will only be in the list: virConnectListDomains not in the list virConnectListDefinedDomains Is that correct? -- bk

[libvirt] LXC: init problem
by Robin Green 11 Jan '10

11 Jan '10

I'm trying to install Exherbo Linux in an LXC container using libvirt. I've basically succeeded, in that I can "virsh console" in and start sshd, but I haven't managed to boot it starting from /sbin/init rather than /bin/bash. If I have the following (I probably should have modified the uuid and the mac address from the standard example, but that's not relevant): <domain type='lxc'> <name>exherbo</name> <uuid>a4047015-171c-ae56-bc1e-57102d4b86bf</uuid> <memory>1000000</memory> <currentMemory>1000000</currentMemory> <vcpu>2</vcpu> <os> <type arch='i686'>exe</type> <init>/sbin/init</init> </os> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/usr/libexec/libvirt_lxc</emulator> <filesystem type='mount'> <source dir='/home/greenrd/exherbo'/> <target dir='/'/> </filesystem> <interface type='network'> <mac address='52:54:00:56:64:42'/> <source network='default'/> <target dev='veth0'/> </interface> <console type='pty'> <target port='0'/> </console> </devices> </domain> and do virsh --connect lxc:/// start exherbo && virsh --connect lxc:/// console exherbo nothing appears - then if I press Enter, the container dies. In pstree all I see that's relevant is: ├─libvirt_lxc───libvirt_lxc so it looks like init dies. If I run init in gdb in the container I just get: Starting program: /sbin/init Usage: init 0123456SsQqAaBbCcUu Program exited with code 01. so I suppose it could be wanting a runlevel as argument. I'm guessing though that /sbin/init is running in a different mode - telinit mode - as its PID is not 1. Is there any way to get an instant console from the virsh start command, so I can see what's going on? -- Robin

Ah, are you using the version of libvirt that comes with RHEL 5.4? That version has been patched to only look for the qemu-kvm binary in one spot: /usr/libexec/qemu-kvm IIRC. You could try to work with that, but since you are already building upstream KVM, virt-manager, and virtinst, might not be a bad idea to pull upstream libvirt as well. >>> Once i tried to compile the virt-manager-0.8.0, but when i make check, >>> it returns: >>> >>> PYTHONPATH=./..:../graphWidgets/.libs python addhardware.py && touch >>> .tstamp.addhardware.py >>> Traceback (mos! t recent call last): >>> File "addhardware.py", line 32, in ? >>> from virtinst import VirtualCharDevice, VirtualDevice, >>> VirtualVideoDevice >>> >>> when i rpm -ivh virt-manager-0.6.1-8.el5.ia64.rpm, it could work. >>> >>> I don't know why this error occur.

'make check' doesn't work in the virt-manager code base, never taken the time to fix it. You should just be able to 'make && make install', or 'make' and python src/virt-manager.py to run from the source dir. If running virt-manager then throws an error, report here and Ill try to help. - Cole

[libvirt] Segfault in event-test.c example

Hello, I have been trying to use the domain event C code example but unfortunately it segfaults (signal 11) every time I run it: [root@Spring events-c]# ./event-test myEventAddHandleFunc:221: Add handle 5 1 0xf081a0 0x8f727f8 myEventAddHandleFunc:221: Add handle 7 1 0xf09990 0x8f727f8 myEventAddHandleFunc:221: Add handle 8 1 0xed7940 0x8f727f8 myEventAddTimeoutFunc:251: Adding Timeout -1 0xedefa0 0x8f727f8 myEventAddHandleFunc:221: Add handle 11 1 0xed7940 0x8f727f8 myEventAddTimeoutFunc:251: Adding Timeout -1 0xedefa0 0x8f727f8 main:322 :: Registering domain event cbs Segmentation fault (core dumped) Core was generated by `/root/libvirt-0.7.5/examples/domain-events/events-c/.libs/lt-event-test'.

I have built and installed libvirt-0.7.5 and it and it's tools seem to be operating correctly. My setup is: Intel(R) Pentium(R) 4 CPU 3.00GHz Linux 2.6.18-164.10.1.el5xen #1 SMP Thu Jan 7 21:14:48 EST 2010 i686 i686 i386 GNU/Linux virsh # version Compiled against library: libvir 0.7.5 Using library: libvir 0.7.5 Using API: Xen 3.0.1 Running hypervisor: Xen 3.4.0 I have a project that requires Domain events so I'd very much like to use this code so any help would be appreciated.
