is it possible to run ovirt node on Diskless HW?

Hello, Doing steps in: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/htm... I would like to know is some one succeeded to run the host on a diskless machine? i am using Centos6.6 node with ovirt 3.5. Thanks, Arman. *********************************************************** Dr. Arman Khalatyan eScience -SuperComputing Leibniz-Institut für Astrophysik Potsdam (AIP) An der Sternwarte 16, 14482 Potsdam, Germany ***********************************************************

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.

It is centos 6.6 standard one. a. *********************************************************** Dr. Arman Khalatyan eScience -SuperComputing Leibniz-Institut für Astrophysik Potsdam (AIP) An der Sternwarte 16, 14482 Potsdam, Germany *********************************************************** On Sun, Dec 7, 2014 at 6:04 PM, Doron Fediuck <dfediuck@redhat.com> wrote:

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. Doron ----- Original Message -----
