VMM Snapshot get Crash Consistent state

Hi,
I have 2 instances of Home Assistant running under VMM (the 2nd is a copy of the 1st, then modified) , both have the Guest Agent running.
When live snapshot are created from Synology VMM, the 1st gets a state “File System Consistent” while the 2nd gets “Crash Consistent”. When the VM is not running it gets “File System Consistent”

I read that it happens when no Guest Agent are running but is running on both.

Any clue on how to solve this ?

Regards
Benoit
