Re: [Xen-users] Creation of additional image within a domU

["john maclean" <jayeola@xxxxxxxxx>]

Um, for some reason I don't get any output when i run `fdisk -l`
within a domU. Here is the /etc/fstab for the domU.


[root@cpxvm ~]# cat /etc/fstab
# This file is edited by fstab-sync - see 'man fstab-sync' for details
# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
/dev/sda1       /               ext3    defaults        1 1
/dev/sda2       none            swap    sw              0 0
/dev/sda3       /alpha         ext3    defaults        1 1
none            /dev/pts        devpts  gid=5,mode=620  0 0
none            /dev/shm        tmpfs   defaults        0 0
none            /proc           proc    defaults        0 0
none            /sys            sysfs   defaults        0 0

Created image and run 'xm block attach`. All ok so far. Now it should
be a case of running fdisk within the domU, right?
