> 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:
