Actually there is still some issue around this. When trying to start
another VM, so using even more pmem, there is a different issue now. Error
copied below.
[]# virsh start manual_clone
error: Failed to start domain manual_clone

I am trying to create a VM with added persistent memory using virsh. It
fails when persistent memory namespace size is larger than available system
