Chapter 3. Technology Preview and Deprecated Features

3.1. Technology Preview Features


Technology Preview features are not supported with Red Hat production service-level agreements (SLAs) and might not be functionally complete, and Red Hat does not recommend using them for production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process. For more information see Red Hat Technology Preview Features Support Scope.

The following features are available as Technology Previews in Red Hat Virtualization:

NoVNC console option
Option for opening a virtual machine console in the browser using HTML5.
Websocket proxy
Allows users to connect to virtual machines through a noVNC console.
VDSM hook for nested virtualization
Allows a virtual machine to serve as a host.
Import Debian and Ubuntu virtual machines from VMware and Xen

Allows virt-v2v to convert Debian and Ubuntu virtual machines from VMware or RHEL 5 Xen to KVM.

Known Issues:

  • virt-v2v cannot change the default kernel in the GRUB2 configuration. The kernel configured on the guest operating system is not changed during the conversion, even if a more optimal version is available.
  • After converting a Debian or Ubuntu virtual machine from VMware to KVM, the name of the virtual machine’s network interface may change, and will need to be configured manually.
Open vSwitch cluster type support
Adds Open vSwitch networking capabilities.
Mobile Android app for Red Hat Virtualization.
Shared and local storage in the same data center
Allows the creation of single-brick Gluster volumes to enable local storage to be used as a storage domain in shared data centers.
