I'm curious if there are any future plans to support MicroVMs in Proxmox? https://firecracker-microvm.github.io/ looks very promising for creating very low resource usage VMs (not containers) and is the technology backing AWS Fargate 1.4 without the Docker Engine as outlined in https://www.theregister.co.uk/2020/04/09/aws_revamps_fargate_serverless_containers/.
MicroVM support
- Thread starter ewaldo
- Start date
No plans, because we have LXC containers with much lower ressource usage ...
But I guess it is possible to run such MicroVMs inside LXC or qemu VMs.

qemu support microvm too
https://github.com/qemu/qemu/blob/master/docs/microvm.rst
(no hotplug, no livemigration currently)

Nice, I didn't know about that. Thank you. Having the extra isolation that VMs bring is a benefit as long as there aren't processor vulnerabilities to worry about.
I tried to find some self-hosting equivalent of Fargate / Lambda, for example in Proxmox and I found this post.
At first sight, Firecracker looks good. @ewaldo , @spirit , thank you!
P.S.: I really love LXC but there are not a lot of API and tools to orchestrate them. For example, no official Ansible dynamic inventory for Proxmox.

I see this is a long dead there but we would like to be able to use microvm's for the additional isolation they provide paired with the near-contrainer-like spin time and(?) the cloud-init support.
My last comment has enough +1s that I guess others might find this useful. I intend to investigate the microvm thing and I will post to the forums if I make any progress.
Hi,
I’d like to express interest in native microVM support within Proxmox VE.
My use cases are based on the work described here:
https://wiki.netbsd.org/users/imil/microvm/
In short, I’m using NetBSD microVMs for lightweight, reproducible workloads with very fast boot times and minimal device emulation.
From an operational standpoint, being able to launch such VMs directly from the PVE web console or API (without manual QEMU command-line configuration) would be ideal.
The absence of live migration is not a blocker in my scenario — microVMs can simply reboot on another node if needed.
Is there any technical or roadmap constraint that prevents this from being integrated?
Also, @steevestroke — did you manage to make any progress or practical use since your last post?
Thanks.
