Hi Arman,
Are you working with ovirt node or standard CentOS?
Note that ovirt node is different as it's works like a live cd-
it runs from memory. In order to save some configurations (such
as networking) the local disk is used.
8:38 p.m.
It is centos 6.6 standard one.

For standard centos you may see other issues.
For example, let's assume you have a single NIC (eth0).
If you boot your host and then try to add it to the engine,
the host deploy procedure will create try to create a management bridge
for the VMs using eth0. At this point your host will freeze since your
root FS will be disconnected while creating the bridge.
I've done this ~6 years ago, and it required opening the initrd to handle
the above issue, as well as adding the NIC driver and creating the bridge
at this point. So it's not a trivial task but doable with some hacking.
