It’s possible to install Clear Linux on Cloud Virtual Machines only if the VM supports UEFI Class 3. AFAIK, none mainstream Cloud VM supports UEFI, even Microsoft Azure is still using Hyper-V Generation 1 VM. So, you can ask your VM provider to support UEFI, but I don’t think it will make sense in the near future.

Subject: [Clr-dev] Running Clear Linux in Vultr VPS
Clear Linux is awesome and I'd like to run it in a generic VPS such as those offered by Vultr. Is this not supported? When I run clear-linux-check-config.sh in a Vultr VPS, all checks succeed except for the final check on EFI firmware. Does it need this if it's running in a VM?
The Vultr instances support AVX2 and BMI CPU instructions (they must be Haswell, not Broadwell, because they don't support RDSEED), so we're good on thr CPU side.
When I contacted Vultr about installing Clear Linux and showed them the project-provided KVM starter script, they said:
"The script you've linked appears to be geared toward a user with bare metal access to a KVM hypervisor. In this case I would recommend seeing if a standard installer ISO is available as we will not be able to install from a pre-existing VM container."
Can we get support for using VPSes like Vultr's? I'd very much like to use Clear Linux for my web servers, benchmark it, and write about it. Vultr is a lot like DigitalOcean, but they let you install your own ISOs (relatedly, it will also help to have URLs to Clear Linux installer ISOs, not just the xz and gz compressed img files that are currently available – Vultr and similar VPS providers need a pure ISO build.)
