SUMMARY

Ability to create Volume Snapshots of all attached volumes to an instance from the Powered off Instance.

STEPS TO REPRODUCE

1.) Go to Compute --> Instances 
2.) Click on a Powered off Instance. 
3.) Click on a button to create a Volume Snapshot 

EXPECTED RESULTS

Being able to create a Volume Snapshot of all attached Volumes to an instance from the Instance screen

ACTUAL RESULTS

Today you have to navigate to Storage --> Volumes and take a Volume Snapshot each individual volume when the instance is in a powered off state.

@scottsignal Make sure you enable the global configuration 'kvm.snapshot.enabled' then navigate to the volume of the instance and you should be able to create a volume snapshot of the instance irrespective of the Power status of the instance.

We have kvm.snapshot.enabled set to True. This was generated from feedback we received that its inconvenient to have to navigate to volumes. They felt that it should be reasonable to do this from the instances tab and do a volume snapshot on all volumes attached to that instance in a powered off state.

Do you intend to restore all the volumes simultaneously? If so, what you want is a VM snapshot (without memory).

I had not thought about the restore side, but it would make sense to be able to do the initial creation and restore all volumes attached to an instance simultaneously. And yes, I was assuming that it would be a VM snapshot (without memory). The Instance would be powered off, so it would be clean and no need for a memory snapshot.

@scottsignal Currently, using KVM as the hypervisor, ACS does not support taking disk-only VM snapshots of stopped VMs. I am already working on a feature that will enable this behavior (You can take a look at #9524 if you want). However, I first need to merge #9270 before I can put more energy on this feature. So I expect it will only be available in 4.21.0.0

This sounds good to me. Thanks!
