-------------------------------------
Summary: [Multiple_IP_Ranges] Failed to create ip alias on VR
while deploying guest vm with ip address from new CIDR
Key: CLOUDSTACK-2854
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-2854
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Management Server
Affects Versions: 4.2.0
Environment: CloudStack-Beta-4.2-2-rhel6.3.tar.gz
Reporter: Sanjeev N
Priority: Blocker
Fix For: 4.2.0
Failed to create ip alias on VR while deploying guest vm with ip address from
new CIDR
Steps to Reproduce:
=================
1.Bring up CS in SG enabled Advanced zone with KVM cluster
2.Add two guest ip ranges with different CIDRs in same vlan
3.Deploy guest vm from the first CIDR
4.Deploy another guest vm from the second CIDR
Expected Result:
==============
Deploying guest vm from the 2nd cidr should create ip alias on VR and vm
deployment should succeed with ip address from the 2nd cidr
Actual Result:
===========
IP alias creation failed on router vm
Observations:
============
Observed NPE while creating ip alias in kvm agent log:
