Hi Paul,

One solution is to introduce a small KVM.

Another is to treat your existing box as a kind of hypervisor to your
MythTV application.

Re-work the start-up so that you do reliably get an SSH daemon early
(ie. don't require CentOS to be "fully loaded" in order to SSH in).

You know the sorts of issues that you need to resolve when the box
doesn't start - I can only guess.

Some suggestions:
  - don't automatically mount RAID filesystems, or delay their mounting
    until the system is stable.
  - consider putting the "critical" (MythTV) function into a container,
    which can be started manually from the host.

Adding the KVM may introduce more problems than it solves...
