java.lang.NullPointerException while bringing up RouterVM for the first
time
venkata swamybabu budumuru created CLOUDSTACK-2597:
------------------------------------------------------
Summary: [KVM] [SystemVMTemplate] java.lang.NullPointerException while bringing up RouterVM for the first time
Key: CLOUDSTACK-2597
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-2597
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Network Controller
Affects Versions: 4.2.0
Environment: commit # 85d54cd1c088997dd08f0328984bee1a55703636
Reporter: venkata swamybabu budumuru
Fix For: 4.2.0
Steps to reproduce :
1. Have latest CloudStack build with at least one advanced zone which uses KVM cluster with single host
2. Have at least one non-ROOT domain user
3. login as above non-ROOT domain user and deploy a VM using an ISOLATED network.
Observations :
(i) Above deployVM cmd failed and found the router that was resulted due the vm deployment is in stopped state.
(ii) Found NPE in agent logs. Here is the snippet of the NPE

(iv) Created another non-ROOT domain user and tried to deploy a new VM using ISOLATED network and it went fine without any issues.
(v) From the above observations, I think the issue happens only on first router VM deployment and any successive attempts go fine without any issues.
Attaching all the required logs along with db dump to the bug.
