[libvirt] [PATCH 0/4] Support for sending signals to guest processes

[Daniel P. Berrange]

One of the things people want to be able todo with LXC is to send
arbitrary signals to processes inside the container. This series
introduces a virDomainSendProcessSignal API for that purpose. The
LXC driver impl is limited to sending signals to the "init" pid
(ie pid == 1), but in the future we'll extend this to arbitrary
container PIDs (via /proc/$PID/ns/pid + setns()).

If the QEMU guest agent had a suitable command we could support
this for QEMU too.
