[libvirt] [PATCH 0/3] qemu: monitor: detect more snapshot errors
by Cole Robinson
qemu in Fedora 30 rejects migration if the VM has nested VMX
configured. This means managedsave and snapshots are rejected too.
Unfortunately the scraping we need to resort to with the text monitor
snapshot commands is not detecting that 'savevm' actually failed, so
the snapshot appears to succeed.
https://bugzilla.redhat.com/show_bug.cgi?id=1697997
qemu 4.0.0 will add an 'Error: ' prefix to most hmp command errors
(qemu commit 66363e9a43f), let's use that to detect error as well
Cole Robinson (3):
qemu: monitor: cleanup loadvm error handling
qemu: monitor cleanup delvm error handling
qemu: monitor: check for common 'Error: ' string

[libvirt] [PATCH] news: add note about optional "Removed features" section
by Daniel P. Berrangé
Most releases don't need a "Removed features" section so don't include
it in the template by default, but leave a reminder in case it is
relevant.

[libvirt] [PATCH 0/4] qemu_hotplug: Check for duplicate drive addresses
by Michal Privoznik
This is an alternative approach to:
https://www.redhat.com/archives/libvir-list/2019-March/msg01111.html
which caused regression to which a proposed fix is here:
https://www.redhat.com/archives/libvir-list/2019-April/msg00756.html
One of the selling points was that having this check in
virDomainDefCompatibleDevice() will fix the problem across all drivers.
Well, turns out, some drivers don't care (e.g. lxc) and some have a
different workflow and thus don't need that check.
Michal Prívozník (4):
conf: Expose virDomainSCSIDriveAddressIsUsed

[libvirt] Why virsh domxml-to-native qemu-argv changes PCI slot number
by Tal Attaly
Hi,
I have bridge type interface defined with slot 3 -
<address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
but after running virsh domxml-to-native qemu-argv I get slot 2-
-netdev tap,fd=21,id=hostnet0 -device e1000,netdev=hostnet0,id=net0,mac=f2:ff:ff:ff:ff:07,bus=pci.0,addr=0x2

[libvirt] [PATCH v1 0/4] RFC CPU Model Comparison via QMP
by Collin Walling
This is a preview of the CPU comparison (and soon baseline)
patches. Comments are welcome on all aspects, as they will
help guide the development of the baseline implementation.
The first couple of patches simply refactor code. The first
introduces an XML -> CPU def helper to be used to extract
the CPU definition prior to sending it to the comparison
functions. The second patch refactors some of the code from
CPU model expansion to be later used by comparison and
baseline. Currently, only one of the functions from the
refactoring is reused for comparison. The other two will
come into play when baseline is implemented.
The third is the typical "new capability" patch to introduce
query-cpu-model-comparison and test data for s390x.
The last patch implements the qemuMonitorJSON function for
query-cpu-model-comparison and hooks it up to virsh
hypervisor-cpu-compare.
This is posted as an RFC to make sure these patches are set
in the correct direction before tackling the baseline patches.
Thanks!

[libvirt] [PATCH] testQemuGetLatestCaps: Lower chances of hash collision
by Michal Privoznik
This function creates a list of paths to the latest capabilities
and returns them in a hash table where key is an arch string and
value is the path. Well, we know how many arches there are so
might as well use that as initial hash size.
