Created attachment 406538 [details] Libvirt XMl output for F13 x86_64 guest Description of problem: I'm running live migration tests as part of the Fedora Virtualization test day. I have two x86_64 hosts, A and B, which both are running the latest F-13 packages (versions below). I also have an x86_64 F-13 guest with a single vcpu and 1G of memory installed on host A (full libvirt XML and generated qemu-kvm command-line attached). When I try to do a live migration using libvirt from host A to host B, the migration seems to succeed. However, once the guest reaches the destination, I get these errors in the guest: end_request: I/O error, dev vda, sector 6836383 Buffer I/O error on device dm-0, logical block 803292 lost page write due to I/O error on dm-0 end_request: I/O error, dev vda, sector 1945543 Buffer I/O error on device dm-0, logical block 191937 lost page write due to I/O error on dm-0 JBD2: Detected IO errors while flushing file data on dm-0-8 end_request: I/O error, dev vda, sector 17451543 Aborting journal on device dm-0-8.

This message is a reminder that Fedora 13 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 13. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '13'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 13's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 13 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
I don't really have the time to follow up on this. Given that there have been substantial changes in qemu/libvirt, especially in the migration area, I'm just going to close this bug out. Chris Lalancette
