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 dfedi...@redhat.com wrote: - Original Message - From: Arman Khalatyan arm2...@gmail.com To: users users@ovirt.org Sent: Wednesday, December 3, 2014 6:50:09 PM Subject: [ovirt-users] is it possible to run ovirt node on Diskless HW?

Re: [ovirt-users] is it possible to run ovirt node on Diskless HW?
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.
