After having done a p2v-migration you sometimes have a vm with a huge harddisk and want to resize it. Unfortunately shrinking of xenserver-vm harddisks is not supported by Citrix [1]. But with the following workaround you can help yourself very easily.

  1. add a harddisk with target-size to your vm
  2. boot your vm from the gparted-live-iso [2]
  3. copy and resize the source-partition to the target harddisk
  4. mark the target-harddisk as active


This works with most virtualization products…


PS: For resizing vhd-files there is the following tool.

  2. I was just seeking this information for a while. After 6 hours of continuous Googleing, at last I got it in your website. I wonder what’s the lack of Google strategy that don’t rank this type of informative web sites in top of the list. Generally the top sites are full of garbage.
