Have you tried Cloud Hypervisor? about hocus HOT 3 OPEN

Yes, the main problem was the lack of the discard feature. However, we've already integrated with QEMU and it works great, so it's not a pressing issue for us right now. We wouldn't see any immediate benefits from switching to Cloud Hypervisor at this time.

Hi Sebastian, we did consider it. Here's a short writeup that we did about why we can't use it yet: https://github.com/hocus-dev/hocus/blob/main/rfd/0002-workspace-runtime.md. Is there any specific reason why you're asking?

Hi! I've been working on Cloud Hypervisor for several years and it looked like a great fit for your use case.
Ok I see the only blocker was the discard feature for storage, right? I assume you're using a block device, which means the only thing that's missing is to implement the VIRTIO_BLK_F_DISCARD feature for the virtio-block device. I'm not actively working on the project, but that's definitely something you could ask the community to implement for you (unless you want to do it).
