Re: [fedora-virt] Schroedinger's VM

I'm still a virtualization in Fedora newbie, so forgive me if this is
a stupid question.  Today I started a kernel compile going in a

desktop to see how the compile had gone.  It was still going.  I ran
top, which showed a short-term load of over 4 and a long-term load of
near zero, along with 3 cc1 processes near the top of the list.  As I
sat there puzzling over what had happened, the compile finished.
Other compiles have finished in only a few minutes.  That near-zero
load makes me suspect that the VM simply stopped doing anything while
I was gone.

I've done a couple of more tests now and have seen the same thing.  I
can start a download going, switch to another desktop, wait for
awhile, then switch back.  The download has progressed only a short
amount past when I switched away from that desktop, and (apparently)
abruptly resumes when I switch back to the desktop containing the VM

Is this expected?  Do KVM-based VMs have to be looked at to do
anything?  If so, is there an option somewhere along the lines of

KVM using SDL doesn't have any issues I've ever found running unwatched. I run a bunch of servers that way, starting in tiny windows and parked on an unwatched desktop. Only if I need to look at something do I go there.
