News

Red Hat® Virtualization® is a complete open-source virtualization solution, derived from the Red Hat Enterprise Linux® kernel, Kernel-based Virtual Machine (KVM) technology, and oVirt virtualization management projects.

Request an evaluation

We have identified a potential data loss scenario under certain conditions when using Red Hat Virtualization with Red Hat Gluster Storage as backend.

Red Hat is working on the fix right now and it will be released as an asynchronous update shortly.

red hat virtualization 4.1 FEATURE HIGHLIGHTS

Red Hat CloudForms integration

CloudForms extends integrated support for Red Hat Virtualization 4.1 providing automation and control over exisitng Red Hat Virtualization features such as VM Live Migrate, VM Reconfiguration, and VM Snapshot Management.  With this integration, IT organizations can deploy a single management interface across heterogeneous data center infrastructures while speeding up workload migration and reducing training costs.

Ansible integration

The integration of Ansible and Red Hat Virtualization provides speed, efficiency, and security for the virtualization administration teams.  Ansible 2.3 includes a variety of Ansible modules to deploy and configure Red Hat Virtualization infrastructure including virtual machines, virtual networks, virtual storage, and dynamic inventory enabling application deployment automation on top of VMs using the Ansible stack.  This integration will greatly streamline the administration and operational experience for virtualization administrators and engineers.

Red Hat OpenStack Platform support

Red Hat Virtualization 4.1 helps to bridge the gap between traditional workloads and cloud-enabled workloads.  Red Hat Virtualization 4.1 enhances the integration with OpenStack Glance and with Neutron's native Open vSwitch ml2 implementation services.  This integration also enables the deployment and life cycle support for Neutron agents on the Red Hat Virtualization hosts via Red Hat OpenStack Platform director.

Integration with Red Hat Enterprise Linux 7.3

Red Hat Enterprise Linux and Red Hat Virtualization development continues to remain tightly aligned.  Red Hat Virtualization 4.1 now fully deploys new features available in RHEL 7.3 such as improved Windows support, hot CPU unplug support, and Virt-sparsify, a tool that allows you to reduce the size of a virtual disk by reclaiming unused space.

Advanced storage performance and scale

Red Hat Virtualization 4.1 includes key features that improve workload performance including

  • improvement of storage scale operations performance
    • Storage Pool Manager (SPM) can delegate storage operations to other data center hosts, preventing  host throttling and improving performance when copying volumes in different flows and merging snapshots.
  • Advanced single storage performance
    • Enhanced cold merge of snapshots allows admins to remove snapshots faster when the VM is not running.
  • improved block storage management
    • Block discard support also allows reclamation of storage space from the virtual machine and when deleting a disk from a storage domain.

Software defined networking

Red Hat Virtualization 4.1 delivers software defined netowrking (SDN) capabilities by offering a tech-preview for Open Virtual Network (OVN) for Open vSwitch.  Significant features include:

  • the controller that streamlines data center deployment and operations by enabling isolated overlay networking and subnet management in Red Hat Virtualization.
  • the Open Virtual Network controller that runs on the Red Hat Virtualization Manager and exposes a Neutron-compatible API, which allows the use of existing Neutron automation with minimal changes.

Enhanced High Availability without power management

Red Hat Virtualization 4.1 provides enhanced high availability for mission-critical VMs and is particularly useful for stretched multi-site clusters where loss of a whole data center still allows mission-critical workloads to remain highly available.  The new functionality allows the VM to be restarted even when power management fencing is not enabled or available for the hosts.  The VM locking prevents vDisk corruption and HA is maintained.
