I might even go further and publish all resource statistics over
mDNS.
Maybe people have ideas about this too, securitywise i'm not really

This is already a solved problem - any resource monitoring system can
publish this kind of information. Rich Jones has already written libvirt
plugins for both collectd and nagios to publish VM information, and so
there's no need to re-invent this in libvirtd itself, nor abuse Avahi/mDNS
service discovery for this purpose
