I tried this, but it didn't work, just didn't give any effect I could
see. I only checked with "xm pci-list-assignable-devices", or is there
any other way?

Just a typo, because in the shell it doesnt matter if try "modprobe
xen-pciback", "modprobe xen-pciback 'hide=(01.00.0)'" or "modprobe
xen-pciback foobar" the error message will always be the same.

OK, this actually worked. Thanks!
