I got lazy and I have downloaded

https://sourceforge.net/projects/edk2/files/OVMF/OVMF-X64-r15214.zip/download

recompiled xen-tools by adding to xen-tools/Makefile

CONFIGURE_ARGS+=        --enable-ovmf
CONFIGURE_ARGS+=        --with-system-ovmf=/root/xen/OVMF.fd

and worked pretty much out of the box.

This is Windows Server 2016 Technical Preview 2016, with GPL PV drivers
added to get networking. My config:

builder = "hvm"
memory = 4096
vcpus = 2
name = "Windows"
disk = [ '/dev/zvol/zroot/windows0,raw,hda,w','/root/fat.bin,raw,hdb,w' ]
boot = "c" # Boot to hard disk image
vnc = 2
vnclisten = "0.0.0.0"
usbdevice = 'tablet'
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
acpi = 1
bios = 'ovmf'
vif = [ 'bridge=bridge0' ]

/root/fat.bin is a little partitioned "hard drive" with FAT16 partition
used to provide GPL drivers.
