[libvirt-users] libvirt ESXI driver's capabilities

Hello, I've read a bit about libvirt in the web site, and I couldn't find anywhere whats the VMWare driver is capable of. I'm planning to build something that will let me manage multiple ESXI hosts (without vcenter) and before I hire a developer, I would like to ask if it supports the following items: * creating thin provisioning disks (when creating a new vm for example) * snapshots - create / restore / limit amounts of snapshots * modifications of live machines (if possible) * graphs (is it possible to build graph with libvirt??) * shutdown / pause / restart I really wish there was a document which would show the driver's limitations.. Another question: is there any book / pdf which is updated and can provide the info of what libvirt capabilities are there and how to use them? Thanks, Hetz
