[ovirt-users] oVirt 4.1 - "Create virtual disk - thin provisioning" makes RAW by default not QCOW2

Hi, Just got test setup of oVirt 4.1 running. Seem to be really brilliant piece of software. 1) Defined local storage domain. Create virtual disk - thin provisioning makes RAW images by default instead of QCOW2. It preallocated all space in advance. I looked inside META file in the same folder as disk image - it is marked as RAW. May be its converted to RAW because I formatted it as 3 partitions: SWAP + Boot Ext4 + Root Ext4 ? Should I use single Ext4 partition per virtual disk image to keep it QCOW2 ? Is there any way to change this behaviour, or convert RAW into QCOW2 within oVirt? Certainly I can do it with QEMU, but image become unregistered, or may be some functionality become broken. 2) SWAP partition - is it better to create small 1GB SWAP as RAM disk or use 4GB partition on virtual RAW disk, or I’m wrong here ? Thanks in advance. Andrei
