[Bug 1516612] [NEW] vm stuck in build status when compute node is up

Mon Nov 16 12:59:44 UTC 2015

Public bug reported:

I am using nova ( version 2.17.0 ) on a compute node and there is a
server running the controller node

when i try to launch an instance when the nova compute is up, this is
stuck on scheduling state (building task) and i see this error on the
nova-comute.log on the compute node:

i see that my nova/objects/__init__.py is this:

so the NetworkRequestList object is really missing. Any help to fix this
bug ?
