Related to bug #690189. Are you saying the the guest is hung for 20 minutes? If you stop vdsm and contact qemu directly with nc -U /var/vdsm/<vmId>.monitor.socket is the qemu monitor responsive? (help, info status). If not, it is a qemu bug. You should be able to cancel the migration through the monitor interface. The monitor interface isn't responding during these 20 minutes. Closing since we only fix urgent bugs in RHEL5.8. It seems as if we survived this behavior so far. It was not reported by a customer. If I got it right, there is no corruption, and the source vm can be restarted and run properly. Ronen. |
Created attachment 515007 [details] vdsm.log * Create VM with 4GB of RAM. * Migrate VM to 2nd host. * During migration, block connection to 2nd host using iptables. * VM becomes stuck in Not Responding status for ~20 minutes. During this time the VM doesn't respond to ping or any other connection.
