Thanks, can you provide the sosreport for the guest too? Alternatively, could you capture the serial console output on the receiving end? I'm almost sure this is a dup of bug 620490 (embargoed). No, unfortunately that's a log of the kernel; I need a log of the hypervisor. Considering cross-vendor migration isn't supported, I think this bug should either be dropped or at least lowered to priority to Tier2. What to other interested parties have to say about that? Created attachment 476233 [details]
patch to avoid the panic
This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release. in kernel-2.6.18-246.el5 You can download this test kernel (or newer) from http://people.redhat.com/jwilson/el5 Detailed testing feedback is always welcomed. Reproduced the bug on kernel-xen-2.6.18-245.el5, after migrating a HVM guest from AMD x86_64 host to Intel x86_64 host, the Intel host crashed. Verified the bug on kernel-xen-2.6.18-257.el5, after migrating a HVM guest from AMD x86_64 host to Intel x86_64 host, none of the hosts crashed. Migrating a HVM guest from Intel to AMD is also tested, none of the hosts crashed. So change the Status to VERIFIED. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA.
