you need to have nfs enabled on the volume. what i meant is nfs.disable 
off which means nfs is on.

For more info please refer to bug

I am not sure how to do that, but   you may shutdown the vm using the 
command hosted-engine --vm-shutdown which will power off the vm and try 
to remove the networks using vdsclient. (not sure if this is right, but 
suggesting a way)
