Xen devel - Apr 2013 - [PATCH 0/2] Allow xen guests to plug disks of 1 TiB or more

This series fixes an issue where disks of 1 TiB or more cannot be added
to a xen guest. The problem lies in the xen backend driver using a 32 bit
integer xenstore interface to write the number of sectors corresponding
to the file or device that represents the virtual disk.

The first patch adds 64 bit integer write functions to the xenstore
interface. The second patch fixes the xen backend driver to use this new
function, allowing for more than 2147483647 sectors.

Thanks,
Felipe

The patch series looks OK to me, I''ll submit a pull request for it.
Thanks,

Ian,
you might want to apply these two fixes to qemu-xen-traditional.
