Yes, of course. A quick test shows no change - Windows get stuck
at the UEFI shell with some block devices listed (I use "hda" for
Windows), SeaBIOS cannot boot FreeBSD with "xvda". FreeBSD
works with "hda", but I have to mount "/dev/ada0p1".

Hello,

I've just imported Xen 4.7.0-rc6 into the ports tree, could you give it a 
try when you have a moment?

FWIW, I'm going on vacations until the 4th of July, and I will be mostly 
AFK.

Roger.
