Hi,

     I have installed latest upstream master on RHEL7.2. When i try to 
put a host in maintenance which runs HE vm i see that vm does not get 
migrated to another host and host is stuck in "preparing for maintenace" 
state. I see the following errors in the vdsm.log . Can you please help 
me understand why this error is seen?
