Hi.

Unfortunately, you can't modify the vcpus or memory for a fully 
virtualized guest while it's running. If virt-manager is letting you do 
that, that's a bug, we should fix it (I assume the guest is running when 
you do this?).

If the guest is shut down, you should be able to edit the memory 
settings and have the changes persist -- is that the case?
