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...
Do you see messages like:
14:35:01.849: debug : do_open:1205 : node driver 0 Test returned DECLINED
14:35:01.849: debug : do_open:1205 : node driver 1 ESX returned DECLINED
14:35:01.849: debug : do_open:1205 : node driver 2 remote returned DECLINED
14:35:01.849: debug : do_open:1205 : node driver 3 udevDeviceMonitor
returned SUCCESS
in your debug log?
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
that should use a USB device).
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
