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: http://www.virtualization.info/2009/09/red-hat-releases-enterprise-linux-54.html

“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.

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 http://www.virtualization.info/2009/09/red-hat-releases-enterprise-linux-54.html
If you still disagree with me, I am open to hear your doubts.

is necessary to create a cluster, but is not necessary to be a guru … is simple through the web interface RHEV-M

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.

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.

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.
