Windows 7 VirtIO HD resize

[blazestar]

Hi guys,

I recently imported a Windows 7 machine from a physical computer to a PROXMOX VM.

Everything works well, except that I'm trying to resize the HD and it won't let me.

The HD is VirtIO (qcow2).

Right now the disk is 600G
But uses only 40G
So I would like to resize it to 50G

I'm trying to resize like this:

root@proxmox2:~# qm resize 103 virtio0 50G
unable to skrink disk size

Any idea why?

I was following this:
https://pve.proxmox.com/wiki/Resize_disks#qm_command

And noted the following:

For virtio disks:
Windows should see the new size online without reboot with last virtio drivers.

I believe that command works only for enlarging. For shrinking try this on a copy of your VM.
