I'm running openSUSE Leap 42.1 server as a Xen 4.6 Dom0.
I'm working on booting UEFI, PVHVM DomUs.
Current Dom0 packages include, from OBS
xen-4.6.20160218T142520.046e5d0 --> includes "--with-ovmf" support
for UEFI boot
grub2-x86_64-xen-2.02~beta3-305.1 --> include patches for efi command
line paramaeters
kernel-default-4.4.4-1.1.g0c1f87e --> pvops native kernel
I'm installing the Xen PVHVM DomU from openSUSE release ISO.
For a non-UEFI Guest, with attached blkdevs,
xvda, gpt, ext4, "/boot"
xvde, gpt, swap, "swap"
xvdf, gpt, ext4, "/"
the installer procedure completes without error. On Guest reboot, the
Guest is up & running.
For a UEFI Guest, with attached blkdevs,
xvda, gpt, vfat, "/boot/efi"
xvde, gpt, ext4, "/boot"
xvdf, gpt, swap, "swap"
xvdg, gpt, ext4, "/"
the installer procedure again completes without error.
But, on reboot, the Guest drops to the EFI shell.
Repeating install of a UEFI Guest, but this time Arch linux, with
available systemd-boot UEFI bootloader rather than Grub, the UEFI Guest
is up & running.
systemd-boot is a simpler/leaner option for UEFI DomU, It's available
for other OSs, but as I understand, a systemd upgrade will NOT be
provided for Leap 42.1, and, atm, systemd builds at OBS for Leap are not
working.
What additional steps or config enable EUFI Guest boot of openSUSE -- as
installed by installer, with its Grub2 bootloader -- to boot without
dropping to the UEFI shell?
