How do I write my VM's SSH destination?

my-vm.exe.xyz or vm+my-vm@vm.exe.xyz

Usually you ssh to your VM in the obvious way:

```
ssh my-vm.exe.xyz
```

Sometimes our [shenanigans to make that work](https://blog.exe.dev/ssh-host-header)...don't.

When that happens, you can always specify the VM in the username instead:

```
ssh vm+my-vm@vm.exe.xyz
```

Both forms land you the same place. The first one is convenient; the second one always works.
