Kernel parameters (eg. console=...) are going to be embedded inside the guest VM disk image inside a grub configuration or something like that, right? Is there enough here to ensure that I can ship a guest VM disk image that will correctly work (ie. use the right device) for both kernel console output and userspace getty, regardless of what the host is? Reading your post I realise that I'm not sure what I need to do to make this work, since the device may be different. Can something be recommended as part of the spec for this?
