[Users] Newbie: some questions on ovirt

Hello, I am evaluating ovirt as a developer virtualization solution and a virtualizer for fast provisioning of software in SOHO market (I send entire vms preconfigured) I use ovirt on centos6 with glusterfs. So I have these questions that I have not found the reply in forums: - In my lab I use spice protocol in a gigabit ethernet, and I use an old thinkpad as terminal, so I would like to disable compression because spice rendering is slow; - I have created some snapshots but I cannot see them in the snapshot list, what do I need to check? I would like to export/import snapshot for backups and to provision them: can you tell me best way to automatize it? Thanks in advance for help! Mario
