Libguestfs - Nov 2013 - [PATCH 0/4] virt-v2v: Add support for SUSE guest conversions

The following series of patches adds support for converting SUSE guests
through virt-v2v. These changes should not impact non-SUSE guest conversions.

Mike Latimer (4):
  Add perl-Bootloader support to grub packages
  Add conversion support for SUSE guests
  Add SUSE to capabilities db and conf
  Add SUSE support documentation

In addition to adding perl-Bootloader support to grub packages, this patch
also removes '$root' from the list of parameters being passed to check,
as
there is nothing which uses this.

any problems are reported.
