The output from "xm dmesg" and > xend.log follows. Any ideas? PAE or 64-bit? Looks like the target is choking on _PAGE_NX. Probably the target machine does not support it. We discussed silently dropping _PAGE_NX on machines that don't support it but that seems a bit dubious to me. This really needs to be solved by adding CPUID to the save format and doing consistency checking at the target before committing to the migration. 3.0.5 will also have save/restore cancellation, so that at least if things do screw up your guest won't /dev/null. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
