During the conversion process, hd* block devices under Xen are mapped to sd* devices for use under guestfs. These sd devices are later remapped to vd* (or sd/hd) devices, for future use under kvm. The current code fails to track the original hd* device names. This causes subsequent remappings of the block devices (in such places as /etc/fstab, and /boot/grub/menu.lst), to skip the hd* devices,

This is a new conversion module to convert SUSE Linux and openSUSE guests. The converter is based on the RedHat module, and should offer the same functionality on both SUSE and RedHat hosts. There are a few additional messages in this module, such as reporting of packages when installing through zypper or the local virt-v2v repo. These messages don't necessarily flow unless verbose switches
