hi all£¬
     my Engine version is 3.1.2.  and  my Vdsm version  is 4.10.3-10. 
     I created a VM and tried to run it, then some error occoured, the error log is below:
         Exit message: internal error unsupported configuration: Read/write, exclusive access, disks were present, but no leases specified
     The libvirt domain XML did not have <lease> elements which created by vdsm. Must I enable auto_disk_leases in /etc/libvirt/qemu-sanlock.conf and manually set host id in qemu-sanlock.conf ?
