Could you build this?
No Providing fast, isolated Linux VMs for background coding agents requires custom hypervisor/microVM infrastructure and high-density virtualization orchestration.
What it would actually take: The infrastructure needs to orchestrate microVMs using Firecracker or QEMU/KVM running on bare-metal servers, paired with custom containerd/snapshotter backends for sub-second VM boots. The critical challenges include multi-tenant kernel isolation, ephemeral copy-on-write root filesystem branching, low-latency agent RPC/TTY streaming, and strict network sandboxing. This requires deep systems infrastructure, Linux kernel virtualization, and distributed systems engineering.
