1. What is the problem with keeping launched state in the VMCS?
Assuming there is a positive answer to the above:

2. Don't you have to change VMCS ID?

3. Can't it be kept somewhere else other than a list? Current scheme 
allows guest to allocate unlimited amounts of host memory.

4. What is the state of migration / nested vmx again? If vmcs12 is
migrated, this means launched state is not migrated anymore.

Patches 1-3 seem fine.
