Curious about the underpinnings of this.
With traditionally data center hypervisors you can create virtual disk and virtual machines. You can create a virtual machine without a virtual disk. The virtual machine is OS independent.
Is there an aws analogue to this? EBS volumes are of course virtual disks but amis are the whole shebang- the vm AND the storage.
Looks like there is no way to create a blank ami and attach a volume later.
Why is this? Is this because amazon is using a different hypervisor for different platforms (hyper-v) so it needs to know what the OS is before it can create a VM for you?
What if I launch some linux ami, then detach the root volume and attach an EBS volume with windows on it? Will that work and be supported by amazon?
