Public bug reported:

NOTE: tests run against devstack install on Ubuntu 14.04
tests conducted via randomized testing, no definitive test case produced yet, but have repeated this several times.

It appears that deleting a resizing instance can cause the nova compute node to crash with the following error / traceback:
(more detailed output below)
screen-n-cpu.2014-10-31-081111.log:354289:2014-10-31 11:01:58.093 TRACE oslo.messaging.rpc.dispatcher   File "/usr/lib/python2.7/dist-packages/libvirt.py", line 896, in createWithFlags
screen-n-cpu.2014-10-31-081111.log:354290:2014-10-31 11:01:58.093 TRACE oslo.messaging.rpc.dispatcher     if ret == -1: raise libvirtError ('virDomainCreateWithFlags() failed', dom=self)
screen-n-cpu.2014-10-31-081111.log:354291:2014-10-31 11:01:58.093 TRACE oslo.messaging.rpc.dispatcher libvirtError: Domain not found: no domain with matching uuid '2aadc976-951e-47d6-bb20-9e071a6a89a9' (instance-00000360)

When this is triggered, the compute node will crash and all instances will end up in ERROR state.
Have not perfected the timing parameters, but will provide output from two runs below.

** Affects: nova
