[Bug 1018741] after Xen 4.7 -> 4.8 upgrade, Xen PVHVM/UEFI guests fail to boot; hang @~ OVMF

--- Comment #36 from Gary Ching-Pang Lin <glin@xxxxxxxx> ---
Let's list the problems.

1) The UEFI variables were not changed reliably.
The emulated NvVars is known to be restricted and the variables are saved only
at certain points. Since Xen doesn't support pflash, this is hard to change.
However, with bios_path_override, the Secure Boot issue can be worked around.

2) The system failed at initrd.
Per comment#16, the system dropped into the dracut emergency shell. Does Leap
42.2 DVD work? Just wonder whether there is anything missing in initrd.

3) Customized grub2
Per comment#24, a customized grub2 was created. In this case,
"ovmf-x86_64-ms.bin" should not be used since the new grub.efi cannot be
verified by shim.efi.

(Anything else?)

From my perspective, the real problem is 2) since it's using the default setup
of the bootloader and kernel.
