Add tstest/natlab/vmtest, a high-level framework for running multi-VM
integration tests with mixed OS types (gokrazy + Ubuntu/Debian cloud
images) connected via natlab's vnet virtual network.
The vmtest package provides:
- Env type that orchestrates vnet, QEMU processes, and agent connections
- OS image support (Gokrazy, Ubuntu2404, Debian12) with download/cache
- QEMU launch per OS type (microvm for gokrazy, q35+KVM for cloud)
- Cloud-init seed ISO generation with network-config for multi-NIC
- Cross-compilation of test binaries for cloud VMs
- Debug SSH NIC on cloud VMs for interactive debugging
- Test helpers: ApproveRoutes, HTTPGet, TailscalePing, DumpStatus,
WaitForPeerRoute, SSHExec
TTA enhancements (cmd/tta):
- Parameterize /up (accept-routes, advertise-routes, snat-subnet-routes)
- Add /set, /start-webserver, /http-get endpoints
- /http-get uses local.Client.UserDial for Tailscale-routed requests
- Fix /ping for non-gokrazy systems
TestSubnetRouter exercises a 3-VM subnet router scenario:
client (gokrazy) → subnet-router (Ubuntu, dual-NIC) → backend (gokrazy)
Verifies HTTP access to the backend webserver through the Tailscale
subnet route. Passes in ~30 seconds.
