Nah, you were correct, I thought the other way around. pcictl(8) prints
PCI IDs with unsigned int (%u), but pciback.hide expects hexadecimal
input (this conversion is made by the kernel).

So => pciback.hide=(11:01.0)

So... everything looks ok. Could you copy/paste the content of the
xend.log file (under /var/log/xen/)?

xenstore-ls would help too.
