Daniel was referring to the libvirt udev driver--the libvirt code that
interacts with udev--not to udev itself, which is what you're testing
with udevadm.
Ok, sorry... At least I ensured that udev itself is on...
In any of your logs when you have libvirt debug logging turned on, do you see the message:
Registering udev node device backend
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) ?
These messages are the result of not being able to find the device, which is consistent with the other things you're seeing. These are all symptoms of the node device code not running.
OK, I'll wait for your suggestions... Frederic.
Have you any other Idea? Frederic.

Hi all,
I often update my F12 box with the rawvirt repository, which just installed libvirt 0.7.6. Since that, I cannot enumerate physical devices (and thus get a beautiful error when I start one of my vms

I don't think I changed anything else on that box, and, of course, I
already restarted the libvirt daemon.
I haven't restarted the server itself, because it is currently used, but I could do it if necessary...
I make good use of the qemu hypervisor, and I'm looking forward to solve this issue!
Frederic.
# libvirtd --version libvirtd (libvirt) 0.7.6
# virsh --version 0.7.6
# virsh nodedev-list error :Failed to count node devices error :this function is not supported by the hypervisor: virNodeNumOfDevices
It would appear that the udev driver failed to start - there are probably messages in syslog about the problem
