[PATCH] qemu_migration: check for interface type 'hostdev'
by Kristina Hanicova
When we try to migrate vm, we check if it contains only devices
that are able to migrate. If a hostdev device is not able to
migrate we raise an error with <hostdev/>, but it can actually be
<interface/>, so we need to check if hostdev device was created
by us from interface and show the right error message.

[PATCH] vmx: Parse vm.genid
by Michal Privoznik
The VMware metadata file contains genid but we are not parsing
and thus reporting it in domain XML. However, it's not as
straightforward as one might think. The UUID reported by VMware
is not in its usual string form, but split into two signed long
longs. That means, we have to do a bit of trickery when parsing.
But looking around it's the same magic that libguestfs does:
https://github.com/libguestfs/virt-v2v/blob/master/v2v/input_vmx.ml#L421
It's also explained by Rich on qemu-devel:
https://lists.nongnu.org/archive/html/qemu-devel/2018-07/msg02019.html

lxc container startup error and RFC patch
by Cole Robinson
Hi all,
I'm seeing LXC container startup failures. This is with libvirt git,
fedora 34 host with systemd-248.6-1.fc34.x86_64 (I didn't confirm with
other versions). Reproducer:
sudo virt-install --connect lxc:/// --name test-container --memory 128
--boot init=/bin/sh
Starting install...
ERROR error from service:
GDBus.Error:org.freedesktop.machine1.NoMachineForPID: PID 2145047 does
not belong to any known machine
libvirt 7.0.0 works but 7.1.0+ does not. The root error seems to predate
that, showing up in syslog, but commit 9c1693eff made it fatal:

vircgroup: use DBus call to systemd for some APIs
The error comes from virSystemdGetMachineByPID. The PID that shows up in
the above error message does not match the leader PID as reported by
machinectl. This change fixes the error but I don't know if it's correct
or if it has other implications:

Maybe something else isn't working elsewhere. Clearly we try to add both
pids to the systemd machine, but virSystemdGetMachineByPID is not
working to match the non-leader pid, which is the one that the LXC
driver knows about.
Thoughts?
Can anyone else reproduce?
Thanks,

[PATCH v2 0/2] qemu: Ignore RESET/SHUTDOWN events during startup
by Peter Krempa
Before we resume the CPUs there was no guest code executed so the events
emitted by qemu are purely based on libvirt actions. Ignore them since
they are emitted when we are resetting the machine so that it picks up
hotplugged disks.
