CLOUDSTACK-7182: NPE while trying to deploy VMs in parallel in isolated
network
The following changes are made:
- Check to see if network is implemented changed from 'state ==
Implementing||Implemented' to 'state == Implemented'.
The earlier check was a hack to prevent the issue described below.
- At the time of implementing network (using implementNetwork() method), if
the VR needs to be deployed then
it follows the same path of regular VM deployment. This leads to a nested
call to implementNetwork() while
preparing VR nics. This flow creates issues in dealing with network state
transitions. The original call
puts network in "Implementing" state and then the nested call again tries
to put it into same state resulting
in issues. In order to avoid it, implementNetwork() call for VR is replaced
with below code.
