Overall I've enjoyed the conversation and can appreciate both sides of it here. I find it surprising that a failover solution isn't supported or even listed as an issue if it doesn't change anything except what physical system it is running on. I can grok that it might not be a "Good Idea" for this that or another reason though that doesn't stop anybody from doing things that help drive better savings, stability, uptime etc.
Personally I am a bit more biased to the VMware side right now as they are sharing information, not just marketing statements. At the end of the day I read this blog and others for the technical information added to the conversation.
Jim,
Can we get some reasoning why you won't support it? Is there a known bug? Is there an issue with migration? What is the reasoning behind this statement? Is it because you simply haven't tested it yet? What breaks or doesn't work?
Thanks,
