[ovirt-users] Ovirt 4.2pre Moving disks when VM is running

hi, I have some test enviroment with ovirt "4.2.0-0.0.master.20171114071105.gitdfdc401.el7.centos" 2hosts+2NFS-domains During the multiple disk movement between the domains I am getting this warning: Moving disks while the VMs are running.(this is not so scary red as in 4.1.x :) ) What kind of problems can happen during the movement? Thanks, Arman.
