All failures of kexec related to virtio should be tracked in Bug #645278. This bug is about guest reset during kexec. I was able to reproduce guest reset only with x2apic and it is knows guest bug fixed upstream. I backported the fix to RHEL6. Gleb, so you wasn't able to reproduce this? Amit, can you check this bug with the #645278 fix? (In reply to comment #4) > Gleb, so you wasn't able to reproduce this? Depends on what "this" means. The bug report is very unclear. I was able to reproduce reboot during second kexec. This is guest bug. Patch was posted. Reported virtio issue tracked by another bug (fwiw I was not able to reproduce it). > Amit, can you check this bug with the #645278 fix? *** Bug 655929 has been marked as a duplicate of this bug. *** (In reply to comment #4) > Amit, can you check this bug with the #645278 fix? I can't reproduce it even w/o the fix. 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. Patch(es) available on kernel-2.6.32-92.el6 I can confirm this. I was just bitten by it as well on 2.6.18-238.9.1. Adding noapic fixed it for me. 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. For more information on therefore solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHSA-2011-0542.html |
