Is there some background reading on this feature?
Nothing nicely written up in any one place.
The general idea though is that we'll create an administrative API for
libvirtd. eg a libvirtadmin.so that connects to a dedicated UNIX socket
like /var/run/libvirt/libvirt-admin which has its own RPC program running
separate from the main RPC program. This library / RPC protocol would be
thus independant of any specific HV connection. The original motivation
was to provide the host admin with a way to turn on/off logging levels
without having to restart libvirtd itself. We also wanted a way to inspect
what clients are connected and what API calls they were waiting for
completion of.
