I am not tied to /sys/kvm. We could also use /proc/<pid>/kvm/ for

global list of VMs which we should have anyway).

How about ~/.qemu/guests/$pid?
That makes it hard for perf to find it and even harder to get a list of
all VMs.

Looks trivial to find a guest, less so with enumerating (still doable).

With /proc/<pid>/kvm/guest we could symlink all guest
directories to /proc/kvm/ and perf reads the list from there. Also perf
can easily derive the directory for a guest from its pid.
Last but not least its kernel-created and thus independent from the
userspace part being used.

Doesn't perf already has a dependency on naming conventions for finding debug information?
