** Description changed:
- Launching a recent daily image of disco on azure results in a VM in
- which the hv-kvp-daemon.service fails to start:
+ SRU Justification
+
+ Impact: The KVP daemon fails to start on first boot due to being started
+ before the hv_kvp device appears.
+
+ Fix: Update the hv-kvp-daemon service file to start the daemon after
+ device node appears.
+
+ Regression Potential: The changes are only to the hv-kvp-daemon service
+ file and adding a udev rule, so the worst case regression would be that
+ the service does not start. In testing the service did start as
+ expected.
+
+ Test Case: See comment #15.

hv-kvp-daemon.service fails to start:
$ systemctl status -o cat hv-kvp-daemon.service

KVP starting; pid is:219

The instance was created with:
$ az vm create --resource-group [redacted] --image
Canonical:UbuntuServer:19.04-DAILY:19.04.201903130 --size Standard_D2_v2 --name
disco-0313
As best as I can tell, the /dev/vmbus/hv_kvp isn't available when the
hv-kvp-daemon.service starts, but it is available a few seconds later. Manually
starting the daemon once I can ssh in works.
