an outsider's comment: this path leads to a filesystem... which could
be a very nice idea. it could have a directory for each VM, with
pseudo-files with all the guest's status, and even the memory it's
using. perf could simply watch those files. in fact, such a
filesystem could be the main userleve/kernel interface.

but i'm sure such a layour was considered (and rejected) very early in
the KVM design. i don't think there's anything new to make it more
desirable than it was back then.
