Package: qemu-guest-agent
Version: 1:8.1.2+ds-1~bpo12+1
Severity: serious
Justification: 6
Dear Maintainer,
The problem arose after upgrading from bullseye to bookworm.
All was OK on bullseye, but on bookworm qemu-ga refuse to start with
following messages :
1702295113.963828: debug: disabling command: guest-get-devices
1702295113.963868: critical: error opening channel
'/dev/virtio-ports/org.qemu.guest_agent.0': No such file or directory
1702295113.963873: critical: failed to create guest agent channel
1702295113.963875: critical: failed to initialize guest agent channel
The systemd command looks like :

the fix for me was to add these lines to the guests XML definition:
<channel type='unix'>
<source mode='bind'/>
<target type='virtio' name='org.qemu.guest_agent.0'/>
</channel>
It has always been required to have some channel from host to
the guest kernel for qga to work. virt-manager adds configuration
like this by default. libvirtd itself doesn't, so you have to
configure something like this manually. But nothing ever changed
in this context since the introduction of qemu-guest-agent.
And qga in the guest starts automatically when the channel in the
guest kernel is present, - you don't start it manually.
I'm closing this bug report now, since I still don't understand
what's not working the way it is designed, - for a year already,
there were no more comments from the original reporter about any
of my questions. Feel free to reopen it and give something to
work on, if you think it is incorrect.
Thanks,
/mjt
