| Thread-topic: | [Xen-devel] Crash in hypercall_xlat_continuation with 64bit xen 3.1.1 when migrating a 32bit pv guest |
> I'm seeing a crash in 64bit xen when doing live migration of a 32bit pv > guest under load. The crash does not occur without the load, it > happens with both Red Hat/Oracle and Xensource kernels (el4u5 in this case), > and it takes about 3-5 migrations to trigger the bug. > Below you'll see that the 32bit guest ebx register, stored here in the > 64bit reg variable, is supposed to have the upper 32bits cleared, but > it has 0x00000080 in the upper 32bits. Have you tried pulling through this patch? http://xenbits.xensource.com/xen-unstable.hg?rev/46776e65e679 Ian _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
