XEN with UEFI guest

[Oleg Ginzburg]

Hi,

I recently tried to use the Xen dom0 through UEFI loader and, finally, it
worked! (Thanks to Roger).

Now I try to use UEFI boot method in the guest and for some reason, the
domain does not start.
The documentation says that this option requires extra config params, so I
added an option to port:

However, the guest does not start if I add the necessary option to the
configuration file:

bios='ovmf'


In addition, I do not see anything suspicious in the log:

Any help and tip is welcome.
