Re: CPU oversubscription =?=> spontaneous reboots

That didn't solve it.  One of the first commands that I try to execute in one
domU, which causes activity in the other domU, triggers a reboot.  As if the
change increased the likeliness of the event.

So I pinned each of the domUs' vCPUs: one with `cpus = "4-5"` and the other
with `cpus = "all,^0-5"`.  Also reduced `vcpus` and `maxvcpus` in the latter,
to avoid oversubscription.  Testing...

I still notice in the latter domU that it assigns multiple vCPUs to a single
physical CPU, even when there are enough physical ones to avoid that.  Odd.
