These sound very familiar :-)  These are the states that a Xen VM can be in.

They don't all make a whole lot of sense in the context of KVM.

A KVM VM is just like a Linux process.  You can use the traditional 
process states for a VM.

One thing that's missing from KVM/QEMU is the ability to determine if a 
VM is stopped.  A monitor command is needed to expose that info.

Eek!  That's not going to happen.

The monitor is an RPC protocol that also happens to be human readable.  
It would be real nice to have a client library for that protocol for 
many different languages but, of course, that's what libvirt is :-)
