I wonder if the xleases volume mentioned here refers to ovf_store ?
No, xleases is part of the disk space used internally by oVirt (to manage concurrent access to the resources, e.g. disk image) and shouldn't be touched by the user. OVF store is Open Virtualization Format [1] and it's used for storing these files, see [2] for more details.

* A new xleases volume to support VM leases - this feature adds the ability to acquire a lease per virtual machine on shared storage without attaching the lease to a virtual machine disk.
A VM lease offers two important capabilities:
* Avoiding split-brain. * Starting a VM on another host if the original host becomes non-responsive, which improves the availability of HA VMs.
