Description Haim 2011-04-11 07:23:56 UTC 
Description of problem:

error: 

Thread-36::ERROR::2011-04-11 09:08:44,678::utils::431::vm.Vm::(run) vmId=`c3542f6d-282d-4928-9923-541ff9a96484`::Traceback (most recent call last):
  File "/usr/share/vdsm/utils.py", line 421, in run
    sample = self.sample()
  File "/usr/share/vdsm/vm.py", line 137, in sample
    s = self.VmSampleClass(self._pid, self._ifids, self._vm)

  File "/usr/share/vdsm/libvirtvm.py", line 33, in __init__
    self.rdb = bs[1]
TypeError: 'NoneType' object is unsubscriptable

scenario: 

vdsm losses connection to libvirt, fails to take itself down, but continue to send block-stats over running VMs to libvirt, which doesn't answer, which results this error. 

please catch and handle this exception.

verified, tested libvirt restart, stop, kill -STOP, vdsmd restart, no error.
