Please help me. Thank you. This is a bug in the HVM emulation layer. In some cases it needs to emulate instructions, but it looks like WinXp issues one it was unable to emulate yet. I checked upstream xen-unstable.hg repository there's still no support for this. Please enter a bugzilla ticket with the details from this mail so the problem can be tracked. I'm afraid there's no immediate work around I can think of to make this work, so you might want to try Windows 2k instead which I believe has been getting more upstream testing than XP Regards, Dan. -- |=- Red Hat, Engineering, Emerging Technologies, Boston. +1 978 392 2496 -=| |=- Perl modules: http://search.cpan.org/~danberr/ -=| |=- Projects: http://freshmeat.net/~danielpb/ -=| |=- GnuPG: 7D3B9505 F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 -=| -- Fedora-xen mailing list Fedora-xen@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-xen
