Hi.
I'm wondering if it's possible to modify the kernel line (in my case,
appending "biosdevname=0") on an installed ovirt-node? Adding it during
boot works - I'd just like to know how to make the change persistent.
Thanks,
Jason.

I'm not sure if this is the "right" way to do it, but I was able to:
# mount -o rw,remount /run/initramfs/live
# cd /run/initramfs/lib/grub
edit grub.cfg and add biosdevname=0 to kernel line

You can do that and it will work. You can also add entries to the host
at installation time and they'll be persisted. I don't believe that
this process of editing grub.cfg will persist across upgrades, however.
Could you file an RFE to add a method to edit and persist the grub
command line?
Thanks

You can do that and it will work. You can also add entries to the
host at installation time and they'll be persisted. I don't believe
that this process of editing grub.cfg will persist across upgrades,
however.
How would I add the entries to the host at installation time? By adding
them to the PXE boot options?

command line?
Will do.
