You can do that through libvirt, but that only works for guests started

Looks like we have a layer inversion here. Maybe we need a plugin system -
libvirt drops a .so into perf that teaches it how to list guests and get
their symbols.
Is libvirt used to start up all KVM guests? If not, if it's only used on some
distros while other distros have other solutions then there's apparently no
good way to get to such information, and the kernel bits of KVM do not provide
it.
Developers tend to start qemu from the command line, but the majority of
users and all distros I know of use libvirt. Some users cobble up their
own scripts.
To the user (and to me) this looks like a KVM bug / missing feature. (and the
user doesnt care where the blame is) If that is true then apparently the
current KVM design has no technically actionable solution for certain
categories of features!
A plugin system allows anyone who is interested to provide the
information; they just need to write a plugin for their management tool.
Since we can't prevent people from writing management tools, I don't see
what else we can do.
