So, I setup some basic clustering with Proxmox 3. Nothing fancy yet, no shared storage or block storage yet but I have the ability to migrate VM's from one server to another. Now, my problem is that when creating a VM disk, QCOW2 format is no longer thin provisioned. I'm not sure if this is because of Proxmox 3 vs 2.2 or because I've setup clustering on the server. Either way, it's frustrating because migrating a 500GB file from one server to another takes way too long. When testing, it seems that the only image format to successfully thin provision is VMDK.
Am I missing obvious something here? Thanks.
