My environnement is Fedora18 / Ovirt 3.2 and VDSM vdsm-4.10.3-6.fc18.x86_64.

I use a storage on fiber channel. When creating a VM the disk is created by ovirt.

When starting the VM the disk has not the permission to be accessed by vdsm.

In fact the device for the disk has root:disks as owner/group.

Changing that by 36.36 permit the VM to start and work fine.

But snapshots do not work, and a reboot cause udev to remap the disk to another /dev/dm-* device.

My fedora18 has selinux disabled.

On irc :

<apuimedo> vdsm/storage/blockSD.py: cmd = [constants.EXT_CHOWN, "%s:%s" %

<apuimedo> vdsm/storage/blockSD.py: self.log.error("failed to chown %s", masterDir)

<apuimedo> vdsm/storage/fileUtils.py:def chown(path, user=-1, group=-1):

<apuimedo> vdsm/storage/fileUtils.py: os.chown(path, uid, gid)

<apuimedo> vdsm/storage/lvm.py: cmd = [constants.EXT_CHOWN, USER_GROUP, lv_path]
