Boot speed, but make it spicy
Running MicroVMs in Proxmox VE, the Easy Way
Proxmox fans are obsessed, cautious, and weirdly thrilled about Plan 9
TLDR: A developer made Proxmox launch tiny isolated virtual machines much faster, aiming to bridge the gap between lightweight containers and slower full virtual machines. Commenters are impressed and curious, but the big debate is whether this is genius ready for the mainstream or still too risky for serious use.
A home lab tinkerer has cooked up a way to make Proxmox spin up super-tiny virtual machines with the speed people usually expect from containers, and the comments are basically a mix of applause, temptation, and nervous sweating. The big selling point is simple: you get something closer to a fully isolated mini-computer, but it starts ridiculously fast. For people who run lots of little services at home or in small setups, that’s catnip.
And yes, the crowd absolutely noticed the funniest part: it runs Plan 9. That obscure operating system cameo gave the whole thread a lovable mad-scientist vibe. One commenter was instantly in fan mode — “I see Proxmox blog post I upvote” — which tells you all you need to know about the loyalty in this corner of the internet. Others were more cautious, basically saying: this is cool, but are we sure it won’t explode in production? That was the real drama line running through the discussion: hacky brilliance vs. please ship this officially before I trust it.
There’s also a classic tech-comment-section subplot brewing: if this is so good, should Proxmox bake it in for everyone? One person hinted the idea may finally be worth another serious look, while others started dreaming up bigger combinations with orchestration tools and lightweight clusters. Translation for normal people: the nerds are already planning sequels. The mood is clear — people think this is clever, useful, and just risky enough to make it exciting.
Key Points
- •The article introduces pve-microvm, a Debian package that adds QEMU’s microvm machine type as a managed guest option in Proxmox VE.
- •The project aims to combine the hardware isolation of full VMs with startup performance closer to LXC containers.
- •According to the article, microVM guests boot directly into a kernel with no BIOS, GRUB, or legacy device emulation, reaching a fully networked state with a QEMU agent in under 300 ms.
- •The implementation patches Proxmox qemu-server Perl modules so that `machine: microvm` generates a custom QEMU command line using direct kernel boot and modern virtio devices.
- •The article says the package includes a custom Linux 6.12.22 kernel and supports 21 guest operating systems, including Debian, NetBSD, and Plan9.
