Hi,
With the current master of VDSM after restarting VDSM (e.g. after
upgrading) I noticed that the VMs were not properly initialized and in
PAUSED state. Once checking the logs I found that the cause was here:
Thread-13::INFO::2014-07-10
12:11:56,400::vm::2244::vm.Vm::(_startUnderlyingVm)
vmId=`db614831-3b4b-4010-a989-f7a5ae6fa5d0`::Skipping errors on recovery
Traceback (most recent call last):
File "/usr/share/vdsm/virt/vm.py", line 2228, in _startUnderlyingVm
self._run()
File "/usr/share/vdsm/virt/vm.py", line 3312, in _run

File "/usr/share/vdsm/virt/vm.py", line 3204, in _domDependentInit
self._syncVolumeChain(drive)
File "/usr/share/vdsm/virt/vm.py", line 5686, in _syncVolumeChain
volumes = self._driveGetActualVolumeChain(drive)
File "/usr/share/vdsm/virt/vm.py", line 5665, in
_driveGetActualVolumeChain
sourceAttr = ('file', 'dev')[drive.blockDev]
TypeError: tuple indices must be integers, not NoneType
The reason here seems to be this:
Thread-13::DEBUG::2014-07-10 12:11:56,393::vm::1349::vm.Vm::(blockDev)
vmId=`db614831-3b4b-4010-a989-f7a5ae6fa5d0`::Unable to determine if the

I am running the host on RHEL6.5
Note: I just rebooted the host and started a few more VMs again and when
I restart VDSM I get the same errors again.
