2) make fs those three project.
3) deploy images
4) setting ovirt-engine
5) up 2 ovirt-nodes to ovirt-engine
with the workaround of WIND00440223. modify 'listen_tls = 1' in /etc/libvirt/libvirtd.conf on both nodes side.
6) create storage domain(data) and iso domain
7) upload guest iso image.
8) create a vm and startup it.
9) click Migrate and select another node.
10) click 'OK'
Check the behaving and logs.
* login to guest and check dmesg information.
