There is regression bug in QEMU on Cirrus Driver (-vga)
See mail attached from qemu mailing list.
I need CPUI configuration feature which is available only in xen 3.3 and
upper
but in need precedent version of ioemu-qemu-xen.
Can i build xen 3.3 with ioemu-qemu-xen of 3.2
To run Windows NT properly.
I tried to build and run xen-unstable but it fails.
moreover this is production use so i don't want to have unstable features.
Can you help me on this point please?

i tried latest version of qemu with -vga and it crash on display
resolution switch (eg. switch from 640x480 256bits to 1280x1024 65536bits)
i tried on 0.9.1 and it works well.
so maybe there is a bug.
I'm currently running an NT4 on kvm-86 for testing various bits and
pieces, and that works fine for me - maybe it's a regression between
kvm/qemu-kvm?
I was unable to get the standard NT4 VGA driver to work in anything
other than 16 colours, however I did finally have success with the
ReactOS driver VBEMP which can be found here:
