With lxc:// URI, this is already possible (see virsh lxc-enter-namespace). With qemu:// URI, this isn't really libvirt's thing to do directly; but you might be able to enhance the qemu-guest-agent to run an arbitrary command, then install that agent in your guest, then use libvirt's 'virsh qemu-agent-command' to drive that new agent command. If the changes you want in your guest can be done while the guest is offline, then libguestfs is a great suite of tools for making all sorts of guest disk image modifications (which is as programmatic as you can get for injecting behavior changes into your guest). But actually injecting live processes into a running qemu guest is not possible without setting up some sort of higher-level protocol, such as qemu-guest-agent. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
