Hi Keir:
I found below codes in ChangeSet 11726 caused this issue:
In privcmd_ioctl() of linux-2.6-xen-sparse/drivers/xen/privcmd/privcmd.c:
if (!vma || (msg.va != vma->vm_start) || vma->vm_private_data)
           goto mmap_out;
when we create a VTI domain, vma->vm_private_data !=0 ,so our operation failed.
I'm not familiar with these codes, hope this information is helpful to you.

Good good study,day day up ! ^_^
