Adding an existing disk via Cloudmin to new VMs instead of creating a disk

Operating System:
CentOS/RHEL 5
Description

Hello,

I am trying to use thin-provisioned disks and add them to VMs created via Cloudmin.

Ex:
create new thin provisioned disk:

qemu-img create -f qcow2 /kvm/newdisk.img 50G

Use the above disk for a new VM. Is this possible via cloudmin? if not - what would be the equivalent steps needed to create a new vm and add this as a virtual disk?

Thank you
