Hi all, I was thinking of "booting from iSCSI SAN", which means you'll be using your LUN placed on storage in order to boot your host over the network. In this case you'll might configure your hosts HW to boot from iSCSI and then you'll won't need any HD on your HW. +adding more people to add their comments.
Thanks in advance.

Message-ID: <[email protected]> Content-Type: text/plain; charset=utf-8 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.
