There is, but its a bit sparse in the bug report - this worked for me
on Ubuntu, same problem:

##
So I changed value in /etc/ovirt-guest-agent.conf to look like:
[virtio]
# device = /dev/virtio-ports/com.redhat.rhevm.vdsm
device = /dev/virtio-ports/ovirt-guest-agent.0
##

Then...

##

cat /etc/udev/rules.d/55-ovirt-guest-agent.rules
SYMLINK=="virtio-ports/ovirt-guest-agent.0", OWNER="ovirtagent",
GROUP="ovirtagent"

udevadm trigger --subsystem-match="virtio-ports"
##

After that, the service started for me.
