      Description

      Migrating an offline VM from one storage SR to another causes huge amounts of errors to be logged on a (seemingly random) host in the pool, and segfaults in vhd-util on the pool master.

      Seemingly random host in the pool:

      The disk it's complaining about (tdk) is the 'new' disk / block device XenServer created for the aforementioned storage migration (LVMoiSCSI).**

      After this occurred for 10 minutes or so the whole server locked up and took down all VMs running on the host.
