[SOLVED] Issues getting qemu-guest-agent working on VM

[bigun89]

I'm fairly certain the issue has something to do with the serial device not populating, I think the driver is in place, so I don't know quite what to do at this point.

Trying to list the socket:

# ls -la /dev/virtio-ports/org.qemu.guest_agent.0
ls: cannot access '/dev/virtio-ports/org.qemu.guest_agent.0': No such file or directory

Listing of PCI devices:

Any help is appreciated.

Enabled the CONFIG_VIRTIO_CONSOLE option in the kernel and the issue is resolved.
