Have since learned that what I did was equivalent to using the "persist" command, and known not to work for modprobe and other things early in the boot process.
<div><br>
</div>
<div>Have also discovered that even mounting / read-write and using mount --bind to get at what's "under" /etc doesn't help. Am assuming that the "live-rw" filesystem is created at boot time from an image, and can't be modified short of building from source.
Is that correct?</div>
<div><br>
</div>
<div>It looks like perhaps what I want to do is install the ovirt-node packages onto my OS of choice (CentOS 6.4, currently.) Will do some reading and trying to see if that's possible. I see that it's documented on FC19 but would prefer to remain with CentOS.</div>

<div>Any tips are appreciated of course!<br>

Thanks,</div>

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.</div>

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:</div>

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.</div>

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.</div>

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.</div>
