RHEV Reviews

The primary use case of this solution is for making DNS, website work, DHCP, and other security functions like ID tables and other tools.

The Administration of the Oracle database and the SAP ERP needs improvement.

In the next release. I would like to see some additional features to make it easier, such as improvements to the GUI and the maintenance. The maintenance of Red Hat is difficult.

I have been using this solution for seventeen years.

Red Hat is the most stable system. It's better than other OS solutions.

At first, this solution was deployed on-premises, then I converted it to cloud using VMware tools to make our private cloud on our data center.

This is an open-source solution.

I have always recommended using other platforms versus Windows. I didn't like using any Windows system, Microsoft system or any system with heavy traffic like ERP and Websites.

I recommend Linux.

I would rate this solution a nine out of ten.

Few pros of Red Hat Enterprise Virtualization Hypervisor are- 1) Kernel based virtual machine(KVM) virtualization technology 2) Good application compatibility and interface 3) Memory page sharing 4) NIC bonding 5) Multipath I/O 6) Efficient guest consolidation, live migration and HA 7) SELinux for enhanced security

Few cons of Red Hat Enterprise Virtualization Hypervisor are1) Need to create virtual machine environment per node 2) Issues with clustering 3) Load balancing not very efficient and fails to utilize and distribute network resources.

Red Hat Enterprise Virtualization Hypervisor is an enterprise virtualization solution made by Red Hat. It has been designed for intergration with Virtualization manager with servers. It has robust virtualization management features with proven enterprise security and performance. This Hypervisor is basically based on Kernel Based Virtual Machine. It has inbuilt features such as live migration, high availability (which manages server availability), and zero downtime for the virtual machines.

The solution is a great all-round product. The virtualization is especially good. 

The GUI interface needs improvement. Not 90%, but 50% or 60% of the work is done from the command line and so on, so the GUI needs work because people are looking for an easier way to manage the environment. Right now, if someone is not very familiar with Red Hat and actually is looking to add Red Hat to the environment, they have to take some training. It needs to be easier to use.

The solution could use network virtualization.

The stability is very good. We've had very good feedback on it.

The solution is very scalable.

The technical support is very good.

The initial setup can be a bit complex, but it depends on the deployment itself.

We are resellers of Red Hat. We deal with various deployment models, however, we generally deal with on-premises.

I would recommend the solution. Of course, it depends on what an organization is looking for in terms of virtualization.

I'd rate the solution eight out of ten.

The Ovirt component has flexibility, and is easy to perform integration within a  heterogenous data centre manager with OpenStack or ManageIQ.

It has the possibility to OEM and create a great product with Ovirt as the main component.

It needs a better administrator KB, similar to what Citrix XenDesktop has. Also, they don't know how to sell their great products and don’t really seems to be interested in taking care of their partners who trust and really know their products.

If you have a heterogenous data centre that is specially focused on Linux platforms, this is safe money, and good if you are looking for automation. 

It also offers great integration with DevOps tools.

For any application that requires 100% uptime, 100% of data accessibility, I use these servers. 

Within our organization, there are roughly 100 employees using this solution.

This solution could be more secure. Also, the CPU power could be increased.

I have been using this solution since the very beginning — about eight or nine years.

This solution is very stable. Much more so than similar products.

It's more of an availability solution than a scalable solution.

The initial setup is very easy. Installation takes no longer than one hour.

I installed this solution by myself.

We have to pay extra for vulnerability and fault tolerance.

I would absolutely recommend this solution to others. Overall, on a scale from one to ten, I would give this solution a rating of nine.

There is no other server equivalent to this one available on the market at the moment. Not HP, not IBM, and not Dell.

On-premises

RHEV costs are very low compared to other Virtualization products. RHEV hypervisor supports up to 160 cores and up to 2 TB of RAM on a host machine. Performance and security are key advantages of RHEV. One of the new features are transparent huge pages, where kernel dynamically creates large memory pages for virtual machines, which improves performance for most workloads by reducing the number of times that memory is accessed. It is open source, which means that it is available for use by every one. There is a “Power user portal” feature that helps developer and IT staff with a self-service interface that allows them to provision virtual machines, define templates, and be an administrator to their own environment.

You need to buy support from red hat and you need to renew support every year in order to keep getting support from red hat. Some features are unavailable compared to leading visualization products. RHEV hyper-visor came later into the market than other leading visualization product.

RHEV hyper visor is a cost effective solution for virtualization. Its work on kernel base virtualization systems. Its usage keep growing in the market.
