yesterday i tried to boot Windows7 64bit with the new "Upstream Qemu with Seabios" HVM loader under xen unstable (yesterdays hg pull)
The Windows Installer booted fine from the ISO (after enabling El-Torrito Emulation in Seabios menuconfig), but the Windows Installer soon gave up with a BSOD (STOP 0xA5), much like stated here http://www.coreboot.org/SeaBIOS under "Windows". I have a Screenshot from the BSOD in case the adresses are of any interest.
Any hints, or is this supposed to not work (yet) ?
We haven't yet tested the whole range of possible guests and I haven't personally tried Windows 7 with new qemu+SeaBIOS.
The Wikipage suggests that the issue is related to the ACPI tables and under Xen these are the same as those used by old qemu+ROMBIOS so it may not be the exact same issue. Have you tried the same OS under old qemu? (although I'm sure we would know already if Windows 7 support was broken in xen-unstable...)
The screenshot would probably be useful to see.
