Thanks for this comprehensive list which I hope will help people in search of such offerings.
I've been told panix.com does also provides such service.
I wrote that article because in specific locations that are out of the US and Europe, the offering might be even narrower.
This was not made out of despair finding a nice provider, but because I found the technical challenge interesting (enough to share).
I think it’s a neat idea and shows a very solid understanding of many different concepts. I also have a lot of this kind of knowledge, but fuck me if I would have been able to put all the pieces together like this without a specific need/driver.
The method mentioned in the link you shared is indeed interesting and probably also works with NetBSD among others, but relies on having third party controls
(such as having to select a grub entry and run the installer steps from a cloud control panel).
The reason I experimented and wrote this article was because I thought interesting to find a way to avoid having to rely on any external controls.
Thus this works even on bare metal servers and thanks to QEMU to install absolutely any OS that can boot on QEMU.
