Enlarging image disk space on an existing virtual server (centos 5 guest on centos 5 host - Xen)

  • 772

Is it possible to increase the size of an existing virtual server image (centos 5 guest on centos 5 host - Xen)? I just installed a new guest, and found out that I did not assign enough storage to the guest at install time.

I know I can add virtual storage by mounting to the virtual system, but I would really like to keep the system as simple as possible (one mounted device - one image file per system).

So, is it possible to increase the storage of an image in an existing system, or am I going to have to start over again?

    here is a nice step-by-step guide. but one addition to it:

    instead of using

    dd if=/dev/zero of=/xen/client8xen.img bs=1M seek=10000 count=5000

    you can also use

    dd if=/dev/zero bs=1M count=5000 >> /xen/client8xen.img

    to add the extra space without finding the exact end of your image.
