Summary: Live-Migrating leads to a dom0 Oops and leaves a migrating-xxx domU Product: Xen Version: 3.0.3 Platform: Other OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: Hypervisor AssignedTo: xen-...@lists.xensource.com ReportedBy: xe...@flonatel.org

(Note that this error report looks similar to Bug#1059, but the system behaviour is quiet different; also the Oops and xend.log looks different.)

When live-migrating a domU which runs memtester (see: http://pyropus.ca/software/memtester/) # memtest 400M a kernel Oops occured. (see attached /var/log/kern.log)

Also the following error occured: (see attached /var/log/xend.log) [2007-09-10 19:47:02 xend 2212] ERROR (__init__:1072) Save failed on domain vm02 (30). Traceback (most recent call last): File "/usr/lib/xen-3.0.3-1/lib/python/xen/xend/XendCheckpoint.py", line 100, in save forkHelper(cmd, fd, saveInputHandler, False) File "/usr/lib/xen-3.0.3-1/lib/python/xen/xend/XendCheckpoint.py", line 227, in forkHelper raise XendError("%s failed" % string.join(cmd)) XendError: /usr/lib/xen-3.0.3-1/bin/xc_save 21 30 0 0 1 failed

Afterwards the Guest System vm02 is renamed to migrating-vm02 - it still runs. When trying to shutdown the Guest System, it transforms into a VM Zombie.
