The above example use the `virtio-console` device as the guest console, and this
device may not be enabled soon enough by the guest kernel to get early kernel
debug messages.
When in need for earlier debug messages, using the legacy serial device based
console is preferred:
```
$ ./cloud-hypervisor/target/release/cloud-hypervisor \
--kernel ./linux-cloud-hypervisor/arch/x86/boot/compressed/vmlinux.bin \
--console off \
--serial tty \
--disk ./clear-29160-kvm.img \

# 3. Status
`cloud-hypervisor` is in a very early, pre-alpha stage. Use at your own risk!
