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-Int= el approved optical transceiver is in use. It's easy to override with the = following options: ixgbe.allow_unsupported_sfp=3D1 The usual ways of doing this are either to place it on the kernel command l= ine at boot time, or in /etc/modprobe.d/ixgbe.conf where it would read "opt= ions ixgbe allow_unsupported_sfp=3D1". 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 a= lso 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 plac= e 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 persi= st across reboots? Surely others have run into the same situation when try= ing to support specific devices.
