If I remember correctly the file /etc/rc.d/rc.local is persisted/persistable, so if it's still true in the mean time you can put as a workaround in it modprobe -r ixgbe modprobe ixgbe HIH, Gianluca
Thanks Gianluca! As it turns out, I reinstalled the node with CentOS 6.4 and was then able to configure it from within ovirt-engine 3.3. The only glitch was having to change the cluster's emulated machine type from pc-1.0 to pc, since I've got 3.1 (or 3.0?) level nodes, and the ovirt-engine was upgraded from 3.1 to 3.3 the other day. Up and running VMs on the new node, at least to test! Allen Belletti AVP Ed.

you don't need to "install packages from node" into centos, just point ovirt-engine add-host dialog to the host and it will bootstrap with all needed packages (assuming the target host has the relevant repo configured). to change something in the node you can build your own node as well
Any tips are appreciated of course!

I've been searching the archives and not yet managed to find anything on the subject, so I'm hoping that someone can point me in the right direction.
I am using nodes with Intel 10G network cards. The driver for these cards has been tweaked to complain (and fail to start the interface) if a non-Intel approved optical transceiver is in use. It's easy to override with the following options:
ixgbe.allow_unsupported_sfp=1
The usual ways of doing this are either to place it on the kernel command line at boot time, or in /etc/modprobe.d/ixgbe.conf where it would read "options ixgbe allow_unsupported_sfp=1". Unfortunately I have no idea how to make either of these permanent on an oVirt node.
I'm running the ovirt-node-iso-3.0.1-1.0.2.vdsm.el6.iso image. It has an /etc/modprobe.d directory where changes do not persist across reboots. It also has /config/etc where I've added modprobe.d and modprobe.d/ixgbe.conf. By adding this file to /config/files, I've been able to make it appear in /etc/modprobe.d at boot time. This has no effect. It appears to take place after the ixgbe driver has already been started. If I "rmmod ixgbe" and "modprobe ixgbe" manually, it works fine.
So the general question is, how do I make configuration changes which persist across reboots? Surely others have run into the same situation when trying to support specific devices.
Thanks,

Hi, this sounds interesting! We look into something similar. So just for clarification, we can setup our own customized CentOS, enable the ovirt-repos, and when we add the host via engine, it will automatically setup the correct corresponding vdsm version on the compute node? E.g. we run ovirt 3.2 on the management node, will it pull the current version or the corresponding version? We have some problems with 3.0.1 compute nodes and 3.2 management nodes but the node-iso 2.6.1 runs well. thanks in advance Sven On 04.10.2013 13:44, Itamar Heim wrote:
you don't need to "install packages from node" into centos, just point ovirt-engine add-host dialog to the host and it will bootstrap with all needed packages (assuming the target host has the relevant repo configured).
to change something in the node you can build your own node as well

yes. ovirt supports both the "slimmed down" ovirt-node, or full blown hosts.
E.g. we run ovirt 3.2 on the management node, will it pull the current version or the corresponding version?
it will always install latest versions it finds in the repos. they should all be backward compatible.
We have some problems with 3.0.1 compute nodes and 3.2 management nodes but the node-iso 2.6.1 runs well.
thanks in advance

Hi, thanks again for the answer, we were able to install ovirt-node onto centos 6.4 minimal successfully! On 07.10.2013 11:07, Itamar Heim wrote:

I just wanted to add some information on the problems we ran into when we tried management version 3.2 with ovirt-node 3.0.1: We were able to register the computenode, but when we tried to deploy a new vm, which was CentOS based we got the following error: Unsupported OS-Version Supported machines are: pc RHEL 6.2.0 PC (alias of rhel6.2.0) rhel6.2.0 RHEL 6.2.0 PC (default) rhel6.1.0 RHEL 6.1.0 PC rhel6.0.0 RHEL 6.0.0 PC rhel5.5.0 RHEL 5.5.0 PC rhel5.4.4 RHEL 5.4.4 PC rhel5.4.0 RHEL 5.4.0 PC Maybe you can shed some light on this? Unfortunately I can't provide any logs from the host side as these got replaced with ovirt node 2.6.1, but I can dig into the management-logs if you need additional information. Thanks Sven

to avoid confusion, we'd call this a "host" and install vdsm onto it. we call ovirt-node only the trimmed down one.

Hi, ok I was able to reproduce this bug, here is some information: ManagementNode: oVirt Engine 3.2.3-1.el6 ManagementNode OS: CentOS 6.4 x64_86 We have various "local storage" datacenters on this management node, one being "LocalCenter_v3" with a single host in it.

Hi, if I may, I believe you've hit this bug: https://bugzilla.redhat.com/show_bug.cgi?id=927874 for 3.2 there's workaround: issue "engine-config -s EmulatedMachine=rhel6.4.0 --cver=3.2" and restart engine Yuriy Demchenko On 10/08/2013 02:11 PM, Sven Kieske wrote:

Hi, I can confirm that this fix works, thanks! Shouldn't this small patch get backported for version 3.2? It doesn't seem to be much work? Regards Sven

this isn't "the patch". its the workaround. before .el6 support was added to ovirt, it only supported fedora out of the box, and for .el6 you had to run this config change. (3.2.0 was released fedora only iirc. 3.2.1 added .el6 support and requires this one liner workaround). in 3.3 we added automatic detection of the emulation level, as reported by the first host added to the cluster.
It doesn't seem to be much work?
that's a series of 7 patches... 3.3 should have this behavior (detect fedora or rhel emulation level by first host) automatically.
