James,

To get this working on boot, you need to set the pciback.hide parameter in kernel boot line. But pciback must but compiled inside the kernel (not as module). If you are using CentOS or redhat, probably it is compiled as module.

You could check $(uname -r)-config file and see the options. CONFIG_XEN_PCIDEV_BACKEND=y in xen kernel (dont know in pv_ops).

If these commands are working for you, just make a script for it.

Well it's working, but not solved. I can't go through all those steps
every time. I will need to figure out how to get this to work on boot. I
will try the commands you wrote in the other response and see what
happens. Maybe I will open a ticket with Novell too.

Thanks,
James
