I checked the manpage for qvm-pause and the qubes-os docs but couldn’t find what is “pausing” in the context of a qube. For example, if I pause my sys-whonix what happens, 1/ to sys-whonix qube? Does that qube lose data? 2/ to my greater system which may utilize sys-whonix qube?

So, the sys-whonix is at 10% CPU usage, which impacts my battery usage. S…
