Dear Maintainer,
The problem arose after upgrading from bullseye to bookworm.
What did you upgrade, host or guest system?
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 :
[Unit]
Description=QEMU Guest Agent
BindsTo=dev-virtio\x2dports-org.qemu.guest_agent.0.device
After=dev-virtio\x2dports-org.qemu.guest_agent.0.device
This is the standard qga systemd unit file.
This unit file tells systemd to start qemu-ga *only* if
/dev/virtio-ports/org.qemu.guest_agent.0 device is present.
So it is either present and qga will start okay, or it is
not present, and systemd wont start it. But not both.
I can't reproduce this issue, everything looks and works
like it is supposed to look and work.
Also, there are *lots* of bullseye VMs and hosts has been
upgraded to bookworm, and qemu-ga continues to work just
fine.
I've no idea what to get out of all this.
