We did the math at my previous employer. The cost of running OpenStack, in terms of training and day to day operations was higher than just paying VMware their licens fee. We even had a guy from RedHat help us do the cost analysis, didn't matter, cheaper to just pay VMware. This didn't even include the cost of doing the migration.

I can't imagine it being cheaper to build everything yourself on top of just plain KVM, or even LXC.

Working in a Data Center, we provide various services, including Dedicated Cloud and Shared Cloud. We also evaluated OpenStack years ago... yes, we came to the same conclusion and just use VMWare.

Also factor in the people trained to use VMware. There is always a pool of individuals to hire.
