Migrating SLES from VMWare ESX to XenServer For SuSE Linux Enterprise Server I require a “Helper” virtual machine to mount and repair the file system. This is because SLES recovery console does not include an editor. After migrating SuSE and booting the boot loader fails at: “waiting for device /dev/sda2.” This is as expected because /sda refers to a SCSI bus and on XenServer SuSE actually sees an /hda (IDE) boot device.
