With some more digging, I believe I've found the root of the bug.

So, I've tried to dig into this a little to figure out why there's a
mismatch between hv_kvp_daemon and the installed location of the hv_*
scripts, and it looks like it must be somewhere on the packaging side of
things rather than the build side. In both of the following Makefiles,

Just created a new VM and wondered why enhanced mode logins in hyper-V
weren't working and encountered this.

Hmm, I wonder if the linux-azure kernel has and extra patch(s) that the
generic kernel does not. I'll do some comparisons.

Issue with 'Invalid kvp dependency scripts path /usr/libexec/hypervkvpd'
remains in latest kernel-image bionic 4.15.0-38.41.
Verified azure-kernel 4.15.0-1030.31 for bionic, same VM and environment, and
the issue does *not* appear.

Hi Chris, I added a Cosmic 18.10 bug task. Does this bug only happen in
Cosmic, or is it still happening in Bionic?

Joe, for the 2nd issue initially reported here, about "After the KVP daemon is
being started the following messages appear".
We've noticed a regression for this in 18.10 - daily's and even GA.
Can you please add Cosmic 18.10 to the bug here and re-open or should I send a
new bug report for it?
Did you notice any other issues that occur when testing the test kernel
posted in comment #12. The second issue posted in the bug is resolved
by changing the definition of KVP_CONFIG_LOC in hv_kvp_daemon.c:

I have opened a different bug for the first issue:

Regarding the second issue, as mentioned in comment #13, the tested
kernels did not exhibit issue #2.

At this point, we should probably have two separate bugs to address each
problem. Can we keep this bug for the second issue and create a new bug
for the first issue?

Regarding comment #11:
I have tested both kernels provided with the following results:
- 4.14 Bionic kernel (4.14.0-16-generic) does NOT exhibit issue #2
(missing files), but it does exhibit issue #1 (KVP daemon failure after
boot). Linux-cloud-tools version installed is 4.14.0-16.19.
- 4.15
I built a test kernel which can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1766857/
Can you test this kernel and see if it resolves this bug?
Note about installing test kernels:
• If the test kernel is prior to 4.15(Bionic) you need to install the
linux-image and
Since they might be related, lets focus on the second issue first, which
is cause by the missing files.
I'll set up a test system to try and reproduce.
It seems like this is a regression, but it would be good to confirm.
Can you test these two kernels?
Last 4.14 Bionic kernel:
I have tested Bionic with kernel 4.15.0-22-generic, linux-cloud-
tools-4.15.0-22.24 and linux-tools-4.15.0-22.24 and both issues still
occur.
While testing the above mentioned kernel, I saw the following behavior:
1. Right after booting the system the KVP daemon reports it is active
(running).

Commit 7fa32e5ec28b was mentioned in the descriptions. However, that
commit has been in mainlien since 4.15-rc3, so it's always been in
18.04.
We may want to split the two issues in to two separate bugs, so they
each get addressed.
Do both issues still happen with the latest Bionic kernel? Per
In my own VMs, this does not affect linux-azure, it only affects the
generic 4.15 kernel.
