Offline resize a virtio disk for Windows guest in RHEV 3.2

Latest response

I have a VM with guest Windows Server, the virtual disk is virtIO PREALLOCATED allocation policy.

Is it possible to resize virtual disk?



Starting in RHEV 3.3 it is possible to extend the size of a virtual disk. It does not matter if the disk is Preallocated or Thin-provisioned, and the operation can be done online (while the VM is running.) It is not possible at all to reduce the size of a virtual disk at this time.
