I've successfully installed OpenBSD on a OVH VPS (which has kvm) using
Linux's grub facility to boot an OpenBSD kernel.
I've simply dropped the bsd.rd file into /boot and added the
corresponding menu entry like (you can edit /boot/grub/grub.cfg
directly):
menuentry OpenBSD {
kopenbsd bsd.rd
}
If the machine is using UEFI (but most VPS don't) you can even use
efibootmgr instead.
I think I've done it using
https://themimitoof.fr/installer-openbsd-7-0-sur-gandicloud-vps/
It's in french but only the grub entry is really important. If you
don't have a KVM you will need to provide an autoinstall script.

Re: Convert a Linux VPS to OpenBSD
I have OpenBSD running well on Ramnode right now. I am guessing since you have been using Scaleway that you want something in Europe. I haven't tried their Amsterdam location, but I have been using their North American locations with good success. Also a good provider in Amsterdam is Tilaa. A bit pricier but they have great uptime and have OpenBSD out of the box. With Ramnode I had to create my own image. +1 for Hetzner. Their Germany and Finland locations are good.

Re: Convert a Linux VPS to OpenBSD
Hi! Or using VPS provider that actually supports openbsd could also be a good solution. Hetzner lets you mount an installation ISO through their web interface and install OpenBSD on whatever VPS you've got running. And there's https://openbsd.amsterdam, but I've not yet used their services. Grtz... Nico

Assuming you have console and can do your own install, perhaps doing a Linux install and leaving a chunk of the beginning of the "disk" unallocated, then dd the minirootXX.img over the very beginning of the "disk", then rebooting. This should get you into the OpenBSD installer, assuming you actually overwrote the beginning of the logical disk and not a Linux partition. A hard reset or "power cycle" might work better than a reboot, as you don't want the Linux system updating anything on the disk partition tables after the dd is complete (if "reboot" even works at that point). However, you might want to think long and hard about committing to a VPS that doesn't actively support the OS you wish to install. What works today may faceplant tomorrow and they may not care at all to fix it for you. Nick.

Convert a Linux VPS to OpenBSD
Hello there, This is a bit of a long shot, but I'm trying my luck: There used to be a community thread on Scaleway's documentation website that explained how to convert a Linux instance to an OpenBSD instance, because no OpenBSD ISO image was available in their console. It seems that this doc disappeared as their documentation section has changed format, and I can't find it on archive.org either. I would like to try and apply the same process at another VPS provider. Does anyone remember or know how this was done, and would they be kind enough to summarise it here, please? Thanks! -- Étienne
