I have read several instructional resources from around the net on this, but some conflict with each other, and most are geared toward internally created guests rather than imported QCOW2 files like Whonix uses.
To add/assign more memory to Workstation as a guest, is it sufficient to do:
# virsh setmaxmem Whonix-Workstation 16G --config
# virsh setmem Whonix-workstation 16G --config
…or is extra editing of he config file with sudo-nano necessary as well? If so, what is to be edited? The original .XML file used to set up Whonix during initial install, or a subsequent one created and stored somewhere else in another folder?
