Let's use both APIs. I have to clarify one thing. Although qemu-kvm use -snapshot option. But it is not the snapshot you are thinking about. You don't have to create any snapshot for the images. I only need to add this option to command line. For example, if I want one VM boot on the image A and don't modify anything on the image A, I just simply send this command "qemu-kvm -m 512 imagefile -snapshot -net, network configuartion". So it is actually the same as non-persistent disk option in VMware, and I think that the name "snapshot" is very easy to misunderstand here. About the vmdk on KVM, I think it is an option. The users need to define installtype in VCL database. If it is vmware, KVM module would consider the image file is vmdk type 4. If it is kvm, KVM module would use img instead. So users can decide what they want to use. And by supporting vmdk file, all current vmdk image running on the VMware ESX can be used directly on KVM host without any effort. I think it could be very nice feature in future.

Use qemu-img to create a qcow2 snapshot for non-imaging reservations. Then use virsh for the rest of the process. Once libvirt supports it, then we upgrade that portion. We'll have to decide if we want to try to also use vmdk files formats on kvm. It's a nice feature but not sure if it is a requirement for using vmdk's on kvm hosts. Also there is a virsh snapshot-create which appears to work only on qcow2 based files. I've not successfully created a snapshot that I can boot yet, but it might be another option.
