[Message part 1 (text/plain, inline)]

Hi all, we've noticed that qemu-guest-agent doesn't start reliably on 
virtual machines generated by guix system.
the log file shows the following:

2023-06-12 14:36:14 1686573373.873765: critical: error opening channel 
'/dev/virtio-ports/org.qemu.guest_agent.0': No such file or directory 
2023-06-12 14:36:14 1686573373.873779: critical: failed to create guest 
agent channel 2023-06-12 14:36:14 1686573373.873782: critical: failed to 
initialize guest agent channel

I guess the udev dependency is missing. The following patch seems to do 
the trick here:

diff --git a/gnu/services/virtualization.scm 
b/gnu/services/virtualization.scm index 2e311e3813..b1b7eafd75 100644
