I've recently upgraded a large BizTalk 2004 implementation that was running on physical servers to BizTalk 2006 running virtualized on a VMWare ESX cluster. Our SQL 2005 servers are also on the same cluster with about 700 active users. I would be happy to share knowledge about real-world/line-of-business virtualization, changes in BizTalk deployment from 2004-2006, etc...
I used to deploy with WMI scripting and now use MSI with multiple binding configurations, etc... seems to be working great, but interested in hearing others' experience.
