The drive the VM's are running on have run out of space and this caused all my VM's to go into Paused-Critical state.
To free up some space I want to delete some snapshots I took. Where my snapshot is extended from the main VM with the Now (green arrow) extending the snapshot.
When I try to delete the snapshot I get the following error.
Failed to perform the operation. The virtual machine is not in a valid state to perform the operation.
Any Ideas?
