libvirt users - Nov 2017 - Does libvirt-sanlock support network disk?

Hello,
As we know, libvirt sanlock support file type storage. I wonder *if it
supports network storage.*
I tried *iSCSI*, but found it didn't generate any resource file:
Version: *qemu-2.10 libvirt-3.9 sanlock-3.5*
1. Set configuration:
qemu.conf:
*lock_manager = "sanlock"*

qemu-sanlock.conf:




*auto_disk_leases = 1disk_lease_dir =
"/var/lib/libvirt/sanlock"host_id 1user = "sanlock"group =
"sanlock"*

# systemctl restart sanlock
# systemctl restart libvirtd

2. Start a VM with iSCSI disk and check
*resource file*
VM disk xml:
    <disk type='network' device='disk'>
      <driver name='qemu' type='raw'/>
      <source protocol='iscsi'
name='iqn.2003-01.org.linux-iscsi.localhost.x8664:sn.cb4bfb00df2f/0'>
        <host name='xx.xx.xx.xx' port='3260'/>
      </source>
      <target dev='vda' bus='virtio'/>
      <alias name='virtio-disk0'/>
      <address type='pci' domain='0x0000' bus='0x00'
slot='0x07'
function='0x0'/>
    </disk>

Start VM:
# virsh start iscsi
Domain iscsi started

Check resource file:
# ls  /var/lib/libvirt/sanlock
__LIBVIRT__DISKS__

No resource file generated.

So, does libvirt sanlock only support file or block type storage?

Correct, the code currently ignores locking for any non-local
disk.
