We performed a comparison between RHEV and VMware VSphere based on our users’ reviews in five categories. After reading all of the collected data, you can find our conclusion below.
Comparison Results: Based on the parameters we compared, VMware VSphere got better user reviews. One major difference between the two solutions is that users say that RHEV’s scalability is not great.
"Customers are moving to open source and Red Hat is the leader in this particular space. I think customers feel more confident running Red Hat Virtualization than VMware."
"The most valuable feature of Red Hat Enterprise Virtualization is its pricing."
"It is a stable solution...It is a scalable solution."
"The solution is a great all-round product. The virtualization is especially good."
"The solution is overall very good with all the facilities. It is user friendly, easy to configure, has documentation, and support is available."
"One of the most valuable features of this solution is the popularity of the OS."
"It is easy to deal with when comes to application migration and its compatibility with the multiple component applications."
"The most valuable features of RHEV are all the tools, such as virtualization, management of cloud platforms, and integration of container environments. The solution has good compatibility between virtualization, content management, and cloud management. Having the full set of these tools is the advantage of it."
"The web console is the most valuable feature for me. Because no matter what happens with the server, I can still get to it with the web console."
"The solution allows for very good virtualization."
"The ability to monitor resource utilization."
"This solution is very stable. It's scalable and simple to set up."
"We have seen an improvement in uptime. The whole hardware lifecycle process is easier."
"Production people can quickly reboot the server with ESXi Quick Boot."
"We are able to patch our hosts during production hours with the ability to keep services running."
"vSphere has enabled an enterprise class virtualization environment with a central point of monitoring and management stretched over multiple datacenters (multi-site use), adding all the features of clustering for high-availability and failover, VM migration, and operations."
"The solution could use network virtualization."
"It lags behind in that you need to go to something like Fedora to get all the extra bells and whistles."
"The UI should be more interactive with additional features."
"The solution should be made more user-friendly."
"A few features of the product do not work as well as those in VMware."
"The solution has a very small lifecycle."
"We'd like it if it would be possible on Red Hat Virtualization to possibly connect two or three VMs to the same disk."
"When we do a direct comparison, then obviously VMware does better in terms of having Fault Tolerance and doing active disaster recovery and these kind of things. This is something that can be improved within Red Hat."
"Given that I've been using version seven, it seems that some of the bugs I faced during that version have already been addressed in subsequent updates. Although I haven't personally tested them yet, it appears that these issues have been resolved. In version seven, there was a problem with the network interface not responding due to certain configurations not being properly filtered. However, in version eight, this requirement has been minimized, so the mentioned bug is less likely to occur. Instead of solely addressing these fixes in newer versions, it might be beneficial for them to consider applying these improvements to the older versions as well. This approach could prevent users from feeling compelled to upgrade to version eight solely to avoid encountering the issue, and instead provide updates for version seven users."
"The biggest problem in this solution is the incompatibility of some of the features with some of the drivers installed on servers. For example, if I want to install vSphere on an HPE server, the driver is really different from a Dell server or a Fujitsu server. I need to download different drivers and install them manually, which can be improved by VMware. They can offer a special image to match different servers. We face different problems when we install vSphere on an ESXi server and have different drivers on the storage. ESXi cannot detect different kinds of storage, and they should improve this. We updated our existing version to vSphere 7 in a private environment, but it seems that this version is not very stable. We are facing issues with restarting the host. In earlier versions, such as vSphere 6 or 6.5, we didn't have any such problems. It would be good if VMware can offer specific applications for mobiles to enable us to control the management of all servers by mobile. They should also improve the vCenter GUI because it is currently not compatible, and there are a lot of problems. Some of the options do not appear well in the browser. VMware should spend more time resolving the problems in the GUI."
"It would be ideal if they could integrate billing software so that clients can customize it directly on the virtual machine."
"Technical support could be faster in terms of response times."
"There are certain tools the can't run in parallel and occasionally, in those instances, we have trouble migrating customers from one source to our data center."
"The price is a big issue for us because the market is very competitive in our country, so we can't really push our VMware vSphere products because the customers will prefer to use something cheaper."
"The one area where I would love to see an improvement is the HTML5 client. It's great, but it could get better."
"The Web Client is too slow."
