I am using Xen to create Virtual Machines, but how can I resize the virtual disk image?

Solution:

This solution is to increase your virtual disk size:

cd /var/lib/xen/images/vlinux1

#use dd to create a 1 GB file

dd if=/dev/zero of=Tempfile bs=1024 count=1000000

#append this file to virtual image file (in this case is hda)

cat Tmpfile >> hda

resize2fs -f hda

Not much help, considering /var/lib/xen/images/ is empty.

Instead of /var/lib/xen/images/ cd to the location of your xen images.

I figured that much, but the last command still doesn't work:

Code:

[root@xen100 xen]# resize2fs -f testsrv1.img

resize2fs 1.39 (29-May-2006)

resize2fs: Bad magic number in super-block while trying to open testsrv1.img

Couldn't find valid filesystem superblock.

[root@xen100 xen]# resize2fs -f /dev/hda2

resize2fs 1.39 (29-May-2006)

open: No such file or directory while opening /dev/hda2

[root@xen100 xen]#
