[ovirt-users] Error migrating VM with direct LUN disk

I have a VM with a virtio-scsi disk that is a direct-mapped iSCSI LUN.
I'm trying to migrate it from one node to another (in the process of
updating my system from 3.5.3 to 3.5.5), and it fails migration with:

Thread-1886273::ERROR::2016-01-06 10:31:17,657::migration::161::vm.Vm::(_recover) vmId=`606ae10e-bcac-4bf8-8ad0-e9d76f0c6f43`::unsupported configuration: scsi-block 'lun' devices do not support the serial property

Is this a known bug (maybe fixed in a newer version), something
unexpected, etc.?  Is there a way around it (other than shutting down
the VM)?
