Have since learned that what I did was equivalent to using the "persist" co=
mmand, and known not to work for modprobe and other things early in the boo=
t process.
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 s=
hort of building from source. Is that correct?
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 try=
ing to see if that's possible. I see that it's documented on FC19 but woul=
d prefer to remain with CentOS.
Any tips are appreciated of course!

Subject: [Users] Customizing node configuration
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,
