Worse; newer regions only support hvm. In my case, this rules out London.

The following should get you going:

https://www.prakashsurya.com/post/2017-02-06-creating-a-custom-amazon-ec2-ami-from-iso/

Essentially, if you install any illumos distro you can send the disk image
up
to AWS and create an AMI. If you create the image by installing using Xen
*exactly* as described, you're done. If you're getting the image from
somewhere
else then the phys_path to the disk embedded in the pool will be wrong and
need
to be rewritten, which basically means going into Xen again.

(I don't have Xen, so I'm currently at the stage where my hvm AMI panics on
boot because the pool has got the wrong labels. That's for Tribblix, but the
procedure is identical for any illumos distro. You have a similar issue if
you try
and convert the pv AMI to hvm; it panics because the hardware has changed
underneath. I'm close, but not there yet.)
