We can use the following scenario: * create a PV AMI using the same script * create a small (1G is minimum for EBS afaik) volume * create a single partition on it * copy /boot/* from PV * install grub to MBR of this volume * register an HVM AMI using 2 snapshots: 1) the smal one (/boot) 2) the one used for PV In this case we would share the same root snapshot which can be resized only (I hope), so we can keep the AMIs small and don't need to regenerate them every time we change the root partition size. PROFIT! The next step will be using these AMIs for different instance type with PV and HVM.

Back to the pool since the priority is not that high now.

I don't think we're going to need this.
