[ovirt-users] VM disks Block device

LVM is used underneath the storage domain for disk management in kvm cluster on ovirt. VG which is the storage domain is visbile and active in all hosts in the same datacenter on ovirt. But, LV under this vg (that is the virtual disks of vms) is not active and the corresponding block devices of these LVs is not available on all hosts in cluster. I find only the running VMs LVs are active on the corresponding host. Is this a feature? Is it possible to get a corresponding block device and LV on all hosts in cluster?
