[libvirt] [PATCHv3 0/3] Add usb controller model="none"
by Peter Krempa 02 Aug '12

02 Aug '12

This series adds support for completely disabling USB bus for a host if a user requires this. For this to work a new USB controller model "none" was added that removes the USB bus. This series incorporates fixes for comments of Dan's and Eric's review and is rebased on top of Dan's error handling cleanup.

[libvirt] [PATCH 00/49 v2] Atomic APIs to list objects
by Osier Yang 02 Aug '12

02 Aug '12

v1 - v2: * Fix the stupid mistake - changing the public struct, error out if the new option '--type' for pool-list is specified, and the libvirt is old enough without listAllStoragePools supported. Except the already supported APIs for domain and domain snapshot, this series add the APIs for the left objects, including storage pool, storage vol, network, interface, node device, nwfilter, and secret. * Storage pool: - Support filtering the returned pool objects by active|inactive, persistent|transient, autostart|no-autostart, and pool types. - New options for virsh, --type to accept multiple pool types. * Storage vol: - Simply returns all the vol objects of a pool. * Network: - Support filtering the results using flags active|inactive, persistent|transient, autostart|no-autostart - New options for virsh. * Interface: - Support filtering the results using flags active|inactive. It's still O(n) underlying, as interface driver doesn't manage the objects itself, but using netcf lib instead. And netcf APIs don't support returning the struct yet. * Node Device: - Support filtering the results using capabilities type of the devices. - Extend --cap to accept multiple capability type. * Network Filter: - Simply returns all the objects. * Secret: - Simply returns all the objects. All the affected commands are tested with both new libvirt with the APIs support, or old libvirt without the support. But I still may lose some scenarios. Please review carefully.

[libvirt] [PATCH v4] storage: netfs and iscsi need option srcSpec for resource discovery

[libvirt] [PATCH] shutting down guest vms on host shutdown does not work
by Gerd v. Egidy 01 Aug '12

01 Aug '12

Hi, I originally postet this into the Fedora bugzilla https://bugzilla.redhat.com/show_bug.cgi?id=843836 but was asked by Eric to post it here for review. Currently gracefully shutting down guest vms on host shutdown does not work on Fedora 17, the guests are killed hard on system shutdown. I use: fedora-release-17-1.noarch libvirt-client-0.9.11.4-3.fc17.x86_64 systemd-44-17.fc17.x86_64 But I have looked into current libvirt git and see the same code there so I don't think it is any different with current git, but I have not verified this. The reason is systemd considers libvirt-guests.service to be stopped when the system is running: $ systemctl status libvirt-guests.service libvirt-guests.service - Suspend Active Libvirt Guests Loaded: loaded (/usr/lib/systemd/system/libvirt-guests.service; enabled) Active: deactivating (stop) since Fri, 27 Jul 2012 15:47:31 +0200; 2min 48s ago Process: 1085 ExecStart=/etc/init.d/libvirt-guests start (code=exited, status=0/SUCCESS) Control: 1150 (libvirt-guests) CGroup: name=systemd:/system/libvirt-guests.service └ control ├ 1150 /bin/sh /etc/init.d/libvirt-guests stop └ 2257 sleep 1 libvirt-guests.service is defined as type "simple" in systemd (the default). That means systemd will shut down the service when the start executable is terminated after starting is done. Systemd will not call stop again on system shutdown because it thinks it is already stopped. The solution is to define it as type "oneshot" and set the flag "RemainAfterExit". Then systemd will consider the service as active after startup and will call the stop function on host shutdown. With the attached patch everything works as expected. Please consider merging. Kind regards, Gerd

[libvirt] [PATCH] daemon: Fix crash in virTypedParameterArrayClear
by Jiri Denemark 01 Aug '12

01 Aug '12

Daemon uses the following pattern when dispatching APIs with typed parameters: VIR_ALLOC_N(params, nparams); virDomain*(dom, params, &nparams, flags); virTypedParameterArrayClear(params, nparams); In case nparams was originally set to 0, virDomain* API would fill it with the number of typed parameters it can provide and we would use this number (rather than zero) to clear params. Because VIR_ALLOC* returns non-NULL pointer even if size is 0, the code would end up walking through random memory. If we were lucky enough and the memory contained 7 (VIR_TYPED_PARAM_STRING) at the right place, we would try to free a random pointer and crash. Let's make sure params stays NULL when nparams is 0. --- daemon/remote.c | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) diff --git a/daemon/remote.c b/daemon/remote.c index 80626a2..d25717c 100644 --- a/daemon/remote.c +++ b/daemon/remote.c @@ -989,7 +989,7 @@ remoteDispatchDomainGetSchedulerParameters(virNetServerPtr server ATTRIBUTE_UNUS virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("nparams too large")); goto cleanup; } - if (VIR_ALLOC_N(params, nparams) < 0) + if (nparams && VIR_ALLOC_N(params, nparams) < 0) goto no_memory; if (!(dom = get_nonnull_domain(priv->conn, args->dom))) @@ -1098,7 +1098,7 @@ remoteDispatchDomainGetSchedulerParametersFlags(virNetServerPtr server ATTRIBUTE virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("nparams too large")); goto cleanup; } - if (VIR_ALLOC_N(params, nparams) < 0) + if (nparams && VIR_ALLOC_N(params, nparams) < 0) goto no_memory; if (!(dom = get_nonnull_domain(priv->conn, args->dom))) @@ -1279,7 +1279,7 @@ remoteDispatchDomainBlockStatsFlags(virNetServerPtr server ATTRIBUTE_UNUSED, virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("nparams too large")); goto cleanup; } - if (VIR_ALLOC_N(params, nparams) < 0) { + if (nparams && VIR_ALLOC_N(params, nparams) < 0) { virReportOOMError(); goto cleanup; } @@ -1753,7 +1753,7 @@ remoteDispatchDomainGetMemoryParameters(virNetServerPtr server ATTRIBUTE_UNUSED, virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("nparams too large")); goto cleanup; } - if (VIR_ALLOC_N(params, nparams) < 0) { + if (nparams && VIR_ALLOC_N(params, nparams) < 0) { virReportOOMError(); goto cleanup; } @@ -1818,7 +1818,7 @@ remoteDispatchDomainGetNumaParameters(virNetServerPtr server ATTRIBUTE_UNUSED, virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("nparams too large")); goto cleanup; } - if (VIR_ALLOC_N(params, nparams) < 0) { + if (nparams && VIR_ALLOC_N(params, nparams) < 0) { virReportOOMError(); goto cleanup; } @@ -1883,7 +1883,7 @@ remoteDispatchDomainGetBlkioParameters(virNetServerPtr server ATTRIBUTE_UNUSED, virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("nparams too large")); goto cleanup; } - if (VIR_ALLOC_N(params, nparams) < 0) { + if (nparams && VIR_ALLOC_N(params, nparams) < 0) { virReportOOMError(); goto cleanup; } @@ -2143,7 +2143,7 @@ remoteDispatchDomainGetBlockIoTune(virNetServerPtr server ATTRIBUTE_UNUSED, goto cleanup; } - if (VIR_ALLOC_N(params, nparams) < 0) { + if (nparams && VIR_ALLOC_N(params, nparams) < 0) { virReportOOMError(); goto cleanup; } @@ -3646,7 +3646,7 @@ remoteDispatchDomainGetInterfaceParameters(virNetServerPtr server ATTRIBUTE_UNUS virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("nparams too large")); goto cleanup; } - if (VIR_ALLOC_N(params, nparams) < 0) { + if (nparams && VIR_ALLOC_N(params, nparams) < 0) { virReportOOMError(); goto cleanup; } -- 1.7.11.1

[libvirt] [PATCH 0/3] Fix check-symfile test case & some linkage bugs
by Daniel P. Berrange 01 Aug '12

01 Aug '12

The check-symfile test case was causing problems for people depending on how they configured libvirt. This turns out to be mostly due to a flaw in linking the nwfilter, network and secrets driver. Once those flaws are fixed, the symfile test works in the same way regardless of whether driver modules are enabled

[libvirt] QEMU CPU model versioning/compatibility (was Re: KVM call minutes July 31th)

Moving the CPU models inside the code is a step backwards, IMO. I don't think loading some kind of data from an external file (provided and maintained by QEMU itself) should be considered something special and magic, and make the data there a second-class citizen (that QEMU refuses to give proper support and keep compatibility). But if it will make us stop running in circles every time something related to those files needs to be changed (remember the -no-user-config discussion?), I think I will accept that. -- Eduardo
