Adds kvm-jailbox to Sandboxing & Isolation: persistent libvirt/KVM development VMs with nftables-enforced private-network denial,
clean-trafficanti-spoofing, and a reduced device model.Disclosure: I'm the author. Repo: https://github.com/ertug/kvm-jailbox — the blog post covers the threat model and a full configuration guide.
Differs from the KVM/libkrun entries already listed in that jailboxes are long-lived per-project workstations rather than ephemeral microVMs, and the network policy is inverted: internet access stays unrestricted, while every private address (host, LAN, other VMs, VPNs, metadata IP) is denied.
kvm-jailbox checkverifies this from inside a running guest, port-scanning every private address and failing if any is reachable.Thanks for the extensive list.
