[libvirt] [PATCH python] Fix handling of optional params in blockCopy()
by Nir Soffer 11 Mar '19

11 Mar '19

Commit 2b4bd07e0a22 (Add check for params, nparams being a dictionary) changed the way the optional params argument is treated. If libvirt.virDomain.blockCopy() is called without specifying params, params is None, and the call will fail with: TypeError: block params must be a dictionary This is wrong as params is defined as kwarg, breaking existing libvirt users like oVirt. Remove the check, restoring the previous behaviour.

[libvirt] [PATCH v6 03/14] audio: -audiodev command line option: documentation
by Kővágó, Zoltán 08 Mar '19

08 Mar '19

This patch adds documentation of an -audiodev command line option, that deprecates the old QEMU_* environment variables for audio backend configuration. It's syntax is similar to existing options (-netdev, -device, etc): -audiodev driver_name,property=value,... Although now it's possible to specify multiple -audiodev options on command line, multiple audio backends are not supported yet.

[libvirt] [PATCH] conf: fix title and description for virDomainSetMetadata API
by Pavel Hrdina 08 Mar '19

08 Mar '19

If we pass XML to virDomainDefineXML API with these two elements: ... <title></title> <description></description> ... libvirt correctly ignores these two elements and they will not appear in the parsed XML. However, if we use virDomainSetMetadata API and with "" as value for title or description we will end up with the parsed XML that contains these empty elements. Let's fix the behavior of this API to behave the same as virDomainDefineXML.

[libvirt] [PATCH] qemu: Fix query-cpus-fast target architecture detection
by Boris Fiuczynski 08 Mar '19

08 Mar '19

From: Viktor Mihajlovski <mihajlov(a)linux.ibm.com> Since qemu 2.13 reports the target architecture in a property called 'target' additionally to the property 'arch', that has been used in qemu 2.12 in the response data of 'query-cpus-fast'. Libvirts monitor code prefers the 'target' property over 'arch'. At least for s390(x), target is reported as 's390x' while arch is 's390'. In a later step a comparison is performed against 's390' which fails for qemu 2.13 and later. In consequence the architecture specific data for s390 won't be extracted from the returned data, leading to incorrect values being reported by virsh domstats --vcpu. Changing to check explicitly for 's390' and 's390x'.
