Is it possible to get perf kvm record to record only what's going on
on a single VM? The options seem to be --host (all host data) and
--guest (all VM data).
I'm getting " 74.86% qemu-kvm [unknown] [u]
0x7f3795bc408d", and I think that's because I've got kallsyms loaded
from a particular guest, but not the others.

-p <pid> argument after the record.
