Red Hat Enterprise Virtualization RHEV-M Demo

It seems Red Had is shifting their focus from Xen as their virtualization platform to KVM. Their new Red Hat Enterprise Virtualizaiton solution is based on KVM. It seems that Red Hat Enterprise Virtualizaiton Solution, when combined with their new management tool called RHEV-M will offer many advanced features.

Red Hat Enterprise Virtualization Solution seems to successfully copy many of VMware and other Virtualization vendors features like:

1- Live Migration
2- Load Distribution
3- Clustering & High Availability
4- Memory over Commitment
5- Transparent Memory Page sharing
6- Virtual Machine Snapshot
7- Host maintenance mode & many other feature.

If you have been using VMware for a while all these features should be familiar to you, though Red Hat are promising that their pricing model will be much cheaper than VMware. I have not got to see Red Hat pricing yet, and it will be too early to compare the two products pricing. Before sharing a video of Red Hat Enterprise Virtualization with you, I believe its worth to mention that reading Red Hat data sheet of the product as well watching their marketing demo video make Red Hat Enterprise Virtualization seem too good to be true for the kind of pricing Red hat is promising to offer.

Its worth to note there is one catch to this product at the moment, its not as easy to setup as you expect unless you are a Red Hat guru. In another words if you are not a Red Hat guru & never had setup a Red Hat cluster & GFS, then Red Hat Enterprise Virtualization Solution will be a steep learning curve for you. I really hope Red Hat will look into making their system setup easier and totally independent of how they currently setup clustering. I believe it should be some how included in RHEV-M interface instead of having to use the Red Hat Clustering Interfaces. That have been said I hope you enjoy the video below:


If yo u care to learn more about the product, you might want to look at the great break out session published at:


  1. “In another words if you are not a Red Hat guru & never had setup a Red Hat cluster & GFS, then Red Hat Enterprise Virtualization Solution will be a steep learning curve for you.”

    It looks like your confusing RHEL and RHEV.
    RHEV doesn’t do anything with GFS or ClusterSuite.

  2. Hi Ian,

    I have to disagree with you on this. In order for you to have a high availability setup for your Virtual Machines in Red Hat Enterprise Virtualization Solution you will need to build Red Hat Cluster & GFS. Don’t take my word for it & check out the second video by Red Hat on the following post

    If you still disagree with me, I am open to hear your doubts.

  3. I do disagree, and having installed both RHEV and RHEL I’m sure ….

    RHEV and RHEL are two different products.

    If you only had RHEL and you wanted High availability, clustering etc, the you need RHCS and GFS.

    If you install RHEV then it manages it’s own storage and clustering without GFS or RHCS.

  4. Ian is right, you must create a cluster but is made of a very simple through the web interface RHEV-M( is not necessary to be a guru). other is to create a cluster on RHEL through Red Hat Cluster Suite.

  5. Hi Artur,

    To be honest I have not got the chance to try RHEV-M in the lab yet, but I had just watched quite few videos on how to set it up. I can see that a RHEV cluster that enable live migration and load sharing is easy to create as in the article you are pointing, but to achieve high availability in RHEV you will require to setup GFS & Red Had Cluster Suite which is where I have stated it will require a Red Hat Expert to setup. I have seen no video or document yet that claim RHEV-M will setup GFS or Red Had Cluster Suite for you, but all mention that you will have to set them up manually then integrate them with your RHEV solution to obtain high availability. If you have any different instruction on doing so, please leave a link to it in the comment. Thanks.

    I have installed RHEV-M on Win2003 32bit with servicepack 2, but while adding the hosts to RHEV-M,I got an error “Failed to install host UNSUPPORTED OS 5.4”.
    Meanwhile I have installed Rhel5.4_x86_64 in my host side.

    Any kind of help will be most welcome

    Thanks in advance

  7. Hi Andrew,

    I am not sure why you are getting the error, but few things I would check for:

    Are you using English local or do u have any other local on the machine you are installing the RHEV-M on. Remember only English Local is support by RHEV-M at the moment as per RHEV-M Manual:

    Only the English locale is supported when installing the RHEV Manager on Windows
    Server 2003.

    Do you have Microsoft .NET Framework 3.5 Service Pack 1 installed?

    Do you have Windows Power Shell 1.0 installed?

    Well, sorry but these would be my best guess. I hope they help you out

    I really don’t know if it is relevant anymore, but RHEV has nothing to do with the clustering suite. In fact, GFS setups are not supported under RHEV at all… The only component used by RHEV that is borrowed from the cluster suite is the fence scripts (check it out). The entire clustering model under RHEV is completely different – it is storage based and not network based. Further more, it is much more scalable, it was tested for many of tenths of physical nodes.

  9. Hi Eiad,

    I am trying to install RHEV and have been successful in installing RHEV-Manager and RHEV- Hypervisor on 2 of the machines and moreover I want to add Storage Domain to be able to use it as NFS and upload ISO’s using ISO uploader but I am not able to succeed in that. Could you help me in this as I am stuck at this point of not being able to upload ISO’s to start installing the VM’s.


  10. Hi Sandeep,

    I have to admit that my RHEV experience is kinda limited, specially when it come to NFS.

    I hope another reader will point out the solution.


  11. hi guys,

    i think i can help with most of the RHEV related problems so please let me know if this post is still alive?

  12. Hi Jeet,

    Unfortunately this was quite old post, but I will keep your words on it & if decided to build another RHEV lab I will keep you posted.
