Following description copied from original LP bug:
If the daemon is started and the vmbus is not present it will just
exit with an error: https://git.launchpad.net/~ubuntu-
kernel/ubuntu/+source/linux/+git/mantic/tree/tools/hv/hv_kvp_daemon.c#n1424
Thus, it would make sense to add
"ConditionPathExists=/dev/vmbus/hv_kvp" in linux-cloud-tools-
common.hv-kvp-daemon.service to prevent systemd from starting the
daemon if the device is not there.
[Test Plan]
Start an Azure cloud instance and check for /dev/vmbus/hv_kvp and that
hv-kvp-daemon is running.
Start a non-Azure cloud instance and check that hv-kvp-daemon is not running.
[Regression potential]
Its possible that kv-hvp-daemon is not started when it should be.
