Prerequisites¶
- Xen Orchestra reachable from wherever you run OpenTofu.
- An XO auth token: XO web UI → your user (bottom-left) → Authentication tokens.
- A working guest agent in the bootstrap OS. The address is discovered, not
declared: the provider blocks during create until the agent reports an IPv4
inside
expected_ip_cidr, then hands it to nixos-anywhere. A broken agent means the create times out at 20 minutes.
