XEN: How to boot SLES para-virtual DomU's into the Rescue System for disaster recovery


まず、起動CD/DVDから

/boot/i386/vmlinuz-xen
/boot/i386/initrd-xen

の二つのファイルを /etc/xen/rescue-sles10 などのフォルダを作ってコピーします。

/etc/xen/vm/MyVm ファイルのコピーを rescue-sles10 などの名前にコピーします。
コピーした　rescure-sles10　を編集します。

この状態で保存し、rescure します。
