With a pkg instance of your-patched kernel 5.0.8,

        
https://build.opensuse.org/build/home:pgnd:Kernel:stable/openSUSE_Leap_15.0/x86_64/kernel-source/_log

 and Dom=pvh enabled,

it boots OK,

but still

        efibootmgr -v
                EFI variables are not supported on this system.
                error trace:

Given some of the build 'fun' I've been having today, I'll take a closer look 
at the patched kernel build in the morning -- to make doubly sure I actually 
built correctly.
