Xen users - May 2013 - Accessing dom0's ioport in domU

Hello,

     I am creating a domU with Ubuntu12.04, I need to provide dom0''s
certain ioports(0xcd0-0xcdb) to domU. I have added *ioports = [
"cd0-cdb" ]
*and tried it in the domU, its been not mapped on domU.

     On host I am using xen-4.2 and tool stack xl. Let me know if I have to
add anymore information to config file to grant access to domU

"xl debug-keys q" should dump a bunch of state to the hypervisor
console
("xl dmesg") including which I/O addresses each domain can access. You
should also check for any error messages.

Please can you provide verbose logs of guest create ("xl -vvv
create ...") as well as your guest config file.
