This bug is awaiting verification that the linux-mtk/5.15.0-1030.34
kernel in -proposed solves the problem. Please test the kernel and
update this bug with the results. If the problem is solved, change the
tag 'verification-needed-jammy-linux-mtk' to 'verification-done-jammy-
linux-mtk'. If the problem still exists, change the tag 'verification-
needed-jammy-linux-mtk' to 'verification-failed-jammy-linux-mtk'.


If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.


See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Title:
  Disable hv-kvp-daemon if /dev/vmbus/hv_kvp is not present

Bug description:
  SRU Justification

  [Impact]

  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.
