4. 在logic volume上建立系统：
[code]# mkfs.ext3 /dev/xen-volume/xen-lv
mke2fs 1.39 (29-May-2006)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
4063232 inodes, 8126464 blocks
406323 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=0
248 block groups
32768 blocks per group, 32768 fragments per group
16384 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
4096000, 7962624
Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information:
done
This filesystem will be automatically checked every 38 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
5. 加载logic volume到目录：
# mount /dev/xen-volume/xen-lv /xen/
查看结果：
# df

6. 在/etc/fstab文件里加一行，让logic volume能够自动加载：
/dev/xen-volume/xen-lv /xen ext3 defaults 0 0
