And, it went into rescue, which is not what I want. Or, is this entire issue about some issue with the file system where it should otherwise BE dropping into shell? This is what I'm trying to figure out.

I'll see if there's some other option over KVM for that, or if they (or I) can add it. I'm certain shell is there and available somehow, I just don't know how to get to it.

I suppose, in the meantime, that the rescue CD is intended for a specific purpose then and it's not something you can drop into shell from (at least without physical console access or going through some rescue mode steps)? |
