[PVE-User] LVM/pvesm udev database initialization warnings after import of KVM images

[Frank Thommen]

Dear all,

after having (successfully) imported two KVM disk images from oVirt, LVM 
and pvesm complain about some udev initialization problem:

root at pve01:~# pvesm status

waiting 10000000 microseconds.
   WARNING: Device /dev/dm-9 not initialized in udev database even after

However this doesn't seem to influence the functionality of the VMs.

Any idea what could be the problem and how to fix it?

Thank you very much in advance
