But ctrl+alt+2 is available.Are you trying to boot freedos directly? If so, that''s not going to work (unless you have VT hardware--which you would know if you did). Xen does para-virtualization which means that the guest operating system must be modified to run under Xen. You should have good luck with using something like qemu within a para-virtualized guest if you want to run FreeDOS though.

There''s something going on with domains not fully being destroyed. I know Khoa is looking into something similiar. Perhaps he''s had some luck?

Perhaps he''s had some luck?I''ve seen this when there were two entries in xenstore for domain0. Definitely try blowing away the store (rm -rf /var/lib/xenstored/store/*) and then rebooting... christian _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
