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
