What are we to make of Oracle announcing support for an open stack of cloud foundation software for its distribution of Linux and Xen? Are we seeing a culture clash?

Meanwhile, KVM is a Type-1 hypervisor that’s built into Linux and relies on kernel modules to run virtual machines.

Oracle has made Oracle OpenStack for Oracle Linux distribution generally available so customers can use it with the company's own version of Linux and virtual machine (VM) services.

Oracle VM is the company’s server virtualization product, based on the open-source Xen hypervisor and able to run virtual machines on Windows, Linux or Oracle’s own Solaris OSes.

Previews of virtual machine (VM) images that enable Oracle workloads to run on Windows Azure are now available from Oracle and Microsoft.
