Ok, sorry... At least I ensured that udev itself is on...

Nope, I checked in /var/log/* and libvirt.log in debug mode (which, after 1 1/2 day of "debug" activity enabled, is already 2Gb!)
There is no mention of udev. I think it means that the udev driver is not loaded in libvirt? How could enable it then? (or produce some message telling me why it is not) ?

OK, I'll wait for your suggestions...
