RE: [Xen-ia64-devel] [IPF] Xen3.0.3 RC3 can not create VTI_domain

["Zhang, Xing Z" <xing.z.zhang@xxxxxxxxx>]

Hi Isaku:
        I found below codes in ChangeSet 11726 cause 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 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 ! ^_^

Could you check whether the change sets,
11727:411c6aca255c9be78cab2a91e4131a3e9807ea60 and
11726:e1f3af226a8e8cb32de079b283cdcac718d3e076,
cause the failure?
I guess they broke IA64 foreign domain page mapping.
