Claim Text:
1. A method for providing a cloud environment for provisioning a guest virtual machine instance, wherein the method comprises: deploying a level one hypervisor enabled with nested virtualization capability on each of multiple host operating systems running on a plurality of host nodes within a data center, wherein each of the multiple host operating systems operate in each of two or more virtual clouds, and wherein the two or more virtual clouds include two or more distinct cloud managers, wherein the two or more distinct cloud managers are deployed on a level one hypervisor executing on a host operating system on a management node; deploying a plurality of level two hypervisors on each level one hypervisor deployed on each of multiple host operating systems; provisioning, via the two or more distinct cloud managers within the two or more virtual clouds, multiple guest virtual machine instances of multiple guest virtual machine types on top of the plurality of level two hypervisors, wherein each of the plurality of level two hypervisors has at least one of the multiple guest virtual machine instances provisioned thereon, thereby providing the cloud environment with multiple isolated execution domains within the data center; deploying at least one application instance within each of the multiple guest virtual machine instances; and wherein the steps are carried out by at least one computer device.
