Incorrect error message while creating instance snapshot without memory for a stopped VM (ROOT & DATA disk on different PowerFlex pools)

2026-04-10 09:43:05,535 DEBUG [c.c.v.s.VMSnapshotManagerImpl] (qtp698741991-25:[ctx-8948ca15, ctx-1e54ecb4]) (logid:ea105dce) Creating a snapshot of a running KVM Instance without memory is not supported
2026-04-10 09:43:05,536 INFO  [c.c.a.ApiServer] (qtp698741991-25:[ctx-8948ca15, ctx-1e54ecb4]) (logid:ea105dce) Failed to create Instance Snapshot: Creating a snapshot of a running KVM Instance without memory is not supported

versions

ACS 4.20.3 RC4 + Advanced Zone + KVM hypervisor

Should exist with 4.20.1 & 4.20.2 as well, as per the changes here:
https://github.com/apache/cloudstack/pull/9773/changes#diff-7d772616388f0b97219416327c6db1bcad3c162d0271f245ee903198913aa0d3

The steps to reproduce the bug

1. Deploy a VM with data disk (ROOT & DATA disk on different PowerFlex pools)
2. Stop the VM
3. Take VM snapshot

What to do about it?

Expecting correct state of the VM in the error message.

Instance snapshots without memory is supported with PowerFlex volumes when all volumes are on the PowerFlex storage and different pools (this seems broken here: https://github.com/apache/cloudstack/pull/3724/changes#diff-705d7f4f3bd1b9d599a38327738fab759b6f6a925f405cbbb7de7bef9b586be2) - now, it is supported when all the volumes are on the same PowerFlex pool only.
