Hi Vinay. I never tried to boot the azure kernel on a physical machine,
but I believe it should boot fine. Usually with those test kernels I
simply install all the debian package with:

$ sudo apt install ./*.deb

I will try to install it on physical machine today to check if I have
the same issues.

I usually provide .deb packages for test kernels because they are quick
to build. However, I can provide a test kernel on a PPA if you prefer.
Building the kernel on a PPA has the advantage that we can sign the
kernel image for secure boot. However by default PPAs do not sign kernel
images with our official key. In that case I usually add the PPA key to
the firmware so I can boot the whole stack in secure mode (just keep in
mind that our grub in xenial is still not enforcing the kernel
signature).

With regards to my tests do you see any issues with my environment
(Hyper-V gen2 VM on Win10 Pro host with secure boot and vTPM enabled)?

Title:
  TPM event log does not contain events measured after ExitBootServices

Bug description:
  The TPM event log (/sys/kernel/security/tpm0/binary_bios_measurements)
  does not contain any events that are measured by UEFI after the
  kernel's EFI Boot stub calls ExitBootServices().

  This means that PCR values calculated from the event log will not
  match the actual PCR values on the machine for PCR indices into which
  these events are measured.

  There are upstream patches to fix this in the mainline kernel tree:
