Description Chris Lalancette 2009-07-29 07:09:02 UTC
Description of problem:
If you run the command:

# xm pci-list-assignable-devices

on a freshly booted dom0, you'll get the error:

ls: /sys/bus/pci/drivers/pciback/: No such file or directory

Unfortunately, it's not very informative.  I think we should either:

1)  modprobe pciback when we start up xend, or, if that is deemed to dangerous,

2)  at least tell the user "you need to modprobe pciback for this to work"

I prefer  2). I'll make a small patch for it.
