Hello everyone,

Is it possible to resize a windows image? Right now I have my images as 25GB c:\ and adding ephemeral disks for added space. I have a case where c:\ need to be larger. I was wondering if anyone tested this and if they can provide docs on how to do this.

Thanks, Peter Borghard

If you resize the underliying disk, then boot up the VM, you can usualy resize the disk partion inside the windows gui in the mmc for the disk configuration to expose the extra space to Windows. Shrinking is a bit harder.

OpenStack does have a resize function. For more details see: nova help resize nova help resize-confirm

It moves your image to a bigger flavor (i.e. bigger root disk). That may well do what you need, otherwise I would drop down to the instructions for the hypervisor you are using.

I hope that helps.
