the host-side virtio-serial channel is wired on every launch, so installing
the agent in the guest is the only step.
Port forwards accept `"2222:22"` (explicit, collision-checked up front),
`"auto:22"`, or just `"22"` — auto forms pick a free host port and the launch
result reports what was chosen.
## Quick start
Disposable sandbox from any base image with `qemu-guest-agent` inside:
```
sandbox_vm(base_image="~/vms/ubuntu-agent.qcow2")
# -> overlay created, VM booted, agent waited for, free port forwarded to 22
guest_exec(name="sandbox", command="uname", args=["-a"])
sandbox_destroy(name="sandbox") # stops VM, deletes overlay; base untouched
```
Installing an OS from scratch:
```
image_create(path="~/vms/test.qcow2", size="10G")
launch_vm(name="test", disks=["~/vms/test.qcow2"], iso="~/isos/alpine.iso",
port_forwards=["2222:22"])
# ... install the OS via the serial console log ...
port_forwards=["auto:22"])
# ... drive the installer with vm_screenshot / vm_type_text / vm_send_keys ...
stop_vm(name="test")
launch_vm(name="test", disks=["~/vms/test.qcow2"])
guest_exec(name="test", command="uname", args=["-a"])
