[libvirt-users] Weird behavior with LVM storage pool on host

Hi list, the problem that I'm having seems to be between libvirtd and udev I have two hosts with LVM. The root partition run over this LVM. After booting the machine, if I do "udevadm settle" it responds almost instantly but then if I launch libvirtd the "udevadm settle" command doesn't respond for about 2 to 3 minutes and the only way to solve this is to restart the uded daemon. This behavior happens on both hosts. The only difference between both is that one has the root partition and storage pool over the same LVM group and disk. The other has separate disks and LVM groups. Have someone experienced something like this or can help me how to debug and solve this problem?. Thanks for all. Ernesto
