Kirill, thanks for the response.

What I mean is that if we specify that a guest VM has say 512 MB of
physical RAM when we are initalizing/starting the VM then can we
change it later while the guest is still running. That is, can I later
reduce or increase the amount of physical RAM the guest VM has without
restarting it ?

Thanks
