Hello All,
I've been searching the archives and not yet managed to find anything on th=
e 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-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.
Thanks,
