CentOS 5.2のDomain-0上にCentOS 5.2をインストール。ディスクにイメージファイルを使う場合、virt-installで非常に簡単。

# vitrt-install
Would you like a fully virtualized guest (yes or no)?  This will allow you to run unmodified operating systems. no
What is the name of your virtual machine? centos5
How much RAM should be allocated (in megabytes)? 512
What would you like to use as the disk (file path)? /var/lib/xen/images/centos5-sda.img
How large would you like the disk (/var/lib/xen/images/centos5-sda.img) to be (in gigabytes)? 8
Would you like to enable graphics support? (yes or no) no
What is the install location? http://mirror.centos.org/centos/5/os/x86_64/

“Would you like a fully virtualized guest (yes or no)?”にnoを答えれば準仮想化、すなわちXenのDomain-Uになる。
準仮想化の場合、install location配下のimages/xen/vmlinuzカーネルでブートするようなので、Fedora 9でもいけるかもしれない。

以下はML115 G5でのインストーラ起動までのブートログ。
