Maybe Joe doesn't have the required knowledge (although I doubt that) to
confirm an ldirectord config is sane? Remember, ldirectord != LVS.

Well, there was no response. I looked at it earlier today, thought it
looked sane, but didn't respond as you were so far down the track of
castigating every suggestion being made.

In that case, you missed an *utterly* crucial piece of information. As
you have now found out. If you'd mentioned it in the first place, we
could have gone back and said "ah, Xen, here's the list of gotchas".

ldirectord != LVS. And also != LVS-NAT. There are myriad ways to
configure your LVS, ldirectord is just one of them. Not all of us are
specialists in all variants.

Perfect, and good on you for finding it.
Don't take the above the wrong way - you started with a somewhat bullish
approach, but you missed the vital piece of detail which would have
helped us all help you. Remember that no-one gets paid here, we're all
volunteers, and we all have lives outside of LVS...
Glad you fixed it.
Joe: time to start adding Xen to the HOWTO.
