Yep

VMwear is starting to look like Windoze - adding unneeded functionality just because it can. Moving VMs around from server to server live - is COOL. But why do you need it? If you are on a consolidation binge and utilization is king, then there will be no "extra" capacity to use for this VM move. Most standard DR scenarios utilize development servers to run production - while prod is down. But dev environments are "lightweight" - lower specs than production, so this DR plan usually doesn't work so well.

VMwear is also replacing *NIX process management. Sun rewrote their entire OS (from BSD-based SunOS to SysV Solaris) JUST to be able to do multi-threading and multi-processor. And that happened more than a decade ago. You would think that Solaris is rock solid now (version 1.0, 1.1, 1.2, 1.3 were unusable ...). So why would you trust VMwear to rewrite this same functionality? And are you willing to shoulder the "growing pains" as VMwear gets the kinks out?

Don't get me wrong, I am the proud owner of a VMwear 1.0 license. I supported them when very few people were on their side (and I don't pay for much software). Their workstation solution was superior to SoftWindoze/SoftPC emulators, and it allowed us Linux guys to run Windoze under Linux. It kept Linux "in the game" when there was ALWAYS some critical app that HAD to run in Windoze.
