@amitcsc1989 Can you restart the cloudstack-agent on the KVM and try deploying the VM again?

i have tried with restarting kvm agent service that is working fine but in case of those vm's which are already created . can these changes automatically added post restart of vm from UI.

I believe you need to stop and then start the VM.
