Xen devel - Oct 2006 - below codes in 11726 caused VTI can''t be boot up

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 ! ^_^
