I looked on qemu passing vga pastrough and it seems that quemu uses vga=0
to turnoff cirus vga emulation. Does xen emulate vga card or does it relay
on qemu? I wonder how hard would be to pass vga=0 to qemu ?

In domU's xl cfg add vga="none", added in xen 4.5, you can also backport
this patch to 4.4 if you need (already tested):
