Did you check that the gnttab doesn't overlap a device/RAM region of
your hardware?
I've posted a patch a week ago to find automatically a region for the
grant table [1] in DOM0 memory. It will avoid you to go through the

The "unable to get my domid" looks like an issue with xenstore. Is
xenstored running?
Also, did you built you DOM0 kernel with CONFIG_XEN_BLKDEV_BACKEND?
