Please Welcome Red Hat Virtualization 4.2!

Hi folks, it is now official – Red Hat Virtualization 4.2 (RHV) has been released! This is a huge milestone for the RHV team as 4.2 delivers more in the themes of ease-of-use, automation, and continued tighter integration with the Red Hat portfolio. As many of you know we have been working on this for awhile – with upstream and downstream activities and contributions. Also we have been in active beta since December 2017. So let’s take a quick look at a few cool things focusing on the 3 key themes from above:

Easy-to-Use:  You are going to see a new UI. For many of you it should look familiar – and that is what we want – the RHV 4.2 UI is based on the PatternFly engine that is used throughout the Red Hat portfolio. This is a very good thing as many of you are probably used to it already; it is really a fast performing UI; and it is it easy and intuitive to learn.

Automation: On the RHV team we are big, big  believers in Ansible. It’s an incredibly easy tool to learn to use and it drives major productivity improvements as we can easily create ‘playbooks’ to automate task after task. In RHV 4.2 we have heavily incorporated Ansible into our workflows. The slide below highlights some of our integration work.


Integration:  Closing out on our top three themes of focus in RHV 4.2 is integration. In 4.2 this is a broad category as it covers Red Hat portfolio integration; bundling opportunities; and new activity in our partner ecosystem. On the Red Hat portfolio side we continue to tighten our linkages to our core product peers: CloudForms, Satellite, OpenStack, and Gluster. All out of the box with new functions to better incorporate these products in the world of virtualization.

On the bundling side, we are introducing the Red Hat Virtualization Suite. This is a bundle of RHV and CloudForms. The bundle provides an easier path for people wanting to move to Red Hat Virtualization for their more traditional virtualization needs. Bringing management and some cost savings to the table add to the value of this offer.

We have had an active period in our partner ecosystem with 4.2 We will look at two partners here Cisco and Nvidia. “ACI loves KVM and Red Hat Virtualization” – hey, it is a Cisco quote! Cisco has created a reference architecture that helps to drive scalable virtualization for ACI and RHV 4.2 customer. Cisco’s excellent blog defines the opportunity we have here for Cisco ACI and Red hat customers. Red Hat and Nvidia have been working closely together to bring vGPU powered technical workstation support for AI, big data, and rich graphics use cases into RHV. This has been accomplished as Nvidia vGPU offerings are now supported. You can learn more about this via registering and watching this upcoming June 5 webinar

To close, we believe that RHV 4.2 creates your virtualization bridge to the modern data center. RHV 4.2 is the virtualization foundation for your organization. It affords support for your VM work flows. It helps drive improved ROI of your Red Hat investments with our integrations in Ansible, CloudForms, and OpenStack to name  just a few. Also, it begins a path to the future of virtualization and containers where Red Hat will surely be a leader – check our Red Hat’s Lars Herrmann’s recent Red Hat Summit blog post on this topic – interesting reading!

Hope this helps,

  1. Can you browse data-stores to upload ISOs now in 4.2? Is there a DOCon how to install RHV-m from KS then do what is needed to make a rpm out of it so I can use that in a RHV Self-Hosted Engine automated install replacing my RPM instead of the RHV-m image RPM from RH?

    Replacement of GUIDs on the storage itself in favor or names/labels based on names I’d LOVE to see in 4.3 so that backups, de-depe replication can be farmed out to staorage team who provides the LUNs.

    Does 4.2 bring any increased CFMEfunctionality/integration? (right sizing, etc). Is there an GUI or non-direct DB edit way to create/manage the RO DB user for CF for DWH?

    Is there a blog that say which (Ceph/Gluster) is the right choice for RHV and why? Is there a blog on how to build an IDM Neutron HA cluster as VM(s) on RHV to use as the network provider so that RHV can now do SDN in CFME like AWS/VMware/OSP?

    1. Hi Steven,

      Thanks for checking in and taking the time to ask some questions. I’ll see what I can do to answer them. 🙂

      * Data domains do in fact support ISO images in RHV 4.2, you can upload ISO’s from the UI to data domains, Data Domains will not have restrictions on the storage type, ISO domains are being deprecated and will continue to only support ISO uploads via command-line
      * RHV-M in SHE is a pre-built appliance, so I don’t see the ability to undo that anytime soon
      * Replacement of GUIDs on storage sounds like a great idea for the use case you’re talking about – by all means open an RFE. I’m not being flippant here. RHV 4.2 has well over 220 RFE’s aside from BZ’s because folks like you took the time to open a feature request.
      4.2 does in fact offer increased functionality w/ CFME – right sizing works, Ansible integration, OVN deployment/control, etc
      * As for the DWH DB, I don’t believe that was ever meant to be “managed”, thus the embedded nature of it. (again not a flippant or sarcastic comment, honest.)
      * While there isn’t a blog dedicated to which way to go (Ceph or Gluster) for use with RHV, I will tell you right here to go with Gluster.. there has simply been more work done between the engineering teams for integration, both to validate VM stores as well as hyperconverged. I love Ceph, but the only support with RHV (for the moment) is via iSCSI.. if we can get direct Ceph (via RBD) I’ll change my tune.
      * As for SDN in RHV – it’s there via OVN. OVN is Neutron compatible, and the Ansible roles are included in RHV. And you can launch those playbooks from CFME as part of a self-service portal.. If you go to my non-Red Hat blog (Captain KVM dot Com), I have a series on how to setup OVN in RHV.. As for HA, I believe that capability is there as well, but I haven’t seen it with my own eyes (in action or in code) so I can’t say for sure.

      I hope I hit all of your fantastic points,
