Nested virtualisation becomes nested cloud
It was magic at first, running multiple VMs on one server using a hypervisor. Then the magic was running VMs on a hypervisor that was itself a VM on another hypervisor. What if I told you that there was a cloud that is built on top of other clouds? A sort of cross-cloud cloud? And this cloud allowed you to take your VMs from vSphere and KVM straight into the cloud? No conversion, just copy the VMs to this new cloud.
