[libvirt] [PATCH v3 0/6] Add setting CPU features (CPUID) with libxenlight driver.
by Marek Marczykowski-Górecki
Add support for CPUID setting based on <cpu> element. Since libxl format
support only adjusting specific bits over host CPU, only
mode='host-passthrough' is supported - other values are rejected (including
default 'custom'). This will break some configurations working before (bare
<cpu> element with for example NUMA configuration), but libxl driver never
supported full 'custom' mode - it was silently ignored, which might lead to
some unexpected effects.
Since mode='host-passthrough' …
[View More]is now necessary to specify CPU options, do not
enable nested HVM feature by mere presence of this element, require explicit
enabling "vmx" or "svm" bits. Nested HVM is still in "preview" state, so better
be explicit here.
v2 of this patch series:
https://www.redhat.com/archives/libvir-list/2017-July/msg00050.html
Marek Marczykowski-Górecki (6):
libxl: error out on not supported CPU mode, instead of silently ignoring
libxl: do not enable nested HVM by mere presence of <cpu> element
libxl: add support for CPUID features policy
tests: check CPU features handling in libxl driver
xenconfig: add CPUID handling to domXML <-> xl.cfg conversion
tests: add test case for CPUID in xenconfig driver

[libvirt] [PATCH V3] blockjob: Fix error checking of blockjob status
by Jie Wang
offset and len can also be equal to 0 on failed if blockjob return
status:"BLOCK_JOB_COMPLETED" with error:"File descriptor in bad state",
so it's better to make our decision based on whether 'error' is non-NULL.

[libvirt] [PATCH] qemu_hotplug: use VIR_ERR_NO_DEVICE when target detaching device is not found
by Chen Hanxiao
From: Chen Hanxiao <chenhanxiao(a)gmail.com>
We used VIR_ERR_OPERATION_FAILED when target detaching device
is not found.
That error code VIR_ERR_OPERATION_FAILED is widely used,
so the tools powered by libvirt, such as nova,
can't catch the exact errors from libvirt.
This patch uses VIR_ERR_NO_DEVICE instead.

[libvirt] [PATCH v2 0/3] Storage pool common object fixes
by John Ferlan
v1: https://www.redhat.com/archives/libvir-list/2017-December/msg00543.html
Changes since v1...
* Added a patch to handle a NULL return with pool obj lock
* Alter the IsDuplicate API to use a bool parameter
* Use the IsDuplicate API from the test driver. This would have generated
the correct error message about a duplicate UUID instead of the Duplicate
key that was generated. Ran virt-manager tests prior to Cole's fixes and
of course after.
John Ferlan (3):

[View More]unlock pools on object allocation failure

[libvirt] Qemu Commandline options are ignored during migration
by Tim Foerster
Heyho Guys,
The domain defintion xml allows to extend the qemu command.
For example:
```
<qemu:commandline>
<qemu:arg value='-cpu'/>
<qemu:arg value='SandyBridge,-kvm_steal_time'/>
</qemu:commandline>
```
The options are correctly passed on startup, but the migration will
ignore them. The desination xml is dumped with the flags 1|2|8. (secure,
inactive and migrateable)
`secure` flag is required to keep vnc passwords, and inactive to keep
the metadata …
[View More]section. But i also mentioned that qemu:commandline section
needs inactive flag too.

[libvirt] [PATCH] vhost-user: no need to remove chardev when remove netdev
by linzhecheng
We use virsh detach-device to hot-unplug a vhost-user net card,
and libvirtd will issue qmp_netdev_del, qmp_chardev_remove and
qmp_netdev_del. However, in qmp_netdev_del, qemu will remove
the chardev when cleanup the netdev. So libvirtd has no need to issue
qmp_chardev_remove to qemu any more.
