Hi there are a lot of differences between ESX and VMware Workstation, some are these: ESX: - Bare metal - Free - Needs other application to administrate (vsphere and runs on Windows) - Server operation (if the esx host reboot the guest starts with the physical server) -…

I agree, they really need to work on the implementation of vmotion between the hosts, maybe as a feature of openstack nova-evacuate module. Another thing they should have are heat templates oriented to PaaS solutions, not all the customers want to pay for managed services.
