I've been away on a training course last week, sorry.

I've been working on getting rolling pool upgrades from XCP 1.5 to 1.6
working lately. I've just installed a 1.1 host to test this patch. If it
works the way I'd expect, I'll put it in the final XCP 1.6

Nope, this is it. I need to write up the list of known issues, which
include 1) upgrading issues, 2) "XenServer" splash screen on boot from
CD, and 3) an issue with the event system which is causing xapi to use
too much CPU and network bandwidth while XenCenter (or anything
listening to events) is connected.

I'll send out another email soon with a full XCP 1.6 status update.

Mike
