We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
"Our production servers are running in Linux, and this solution supports that environment well."
"Scaling the solution is easy. You just have to add more hardware."
"I like that this is an open-source solution. It is very powerful, and it's easy."
"The KVM service is well managed with a central policy interface."
"If you prefer command-line, there are all kinds of command-line options."
"It is easy to use, stable, and flexible. It is a pretty mature product, and it is faster than VirtualBox."
"The GUI interface makes the management of KVM easier than ever before."
"This solution is open source and easy to configure."
"One of the most valuable features of this solution is the popularity of the OS."
"The solution is a great all-round product. The virtualization is especially good."
"Red Hat is the most stable system."
"Technically, the main reason why I'm using Red Hat is because of its stability."
"The most valuable feature of this solution is the support portal."
"Stability and speed are the most valuable aspects."
"The price is the solution's most valuable aspect. It's much cheaper than, for example, VMware."
"The solution makes migration easy."
"Support for VF is needed, where you can, for example, export from VMware to KVM."
"The solution should be more user friendly. We are struggling with the command lines."
"The virtual manager and the graphical QEMU for KVM need some improvement."
"The initial setup of this solution is more difficult than some of the competing products and it could be improved."
"One thing that maybe could be improved is making it easier to scale. It needs to be more clear on how to scale the storage space for virtual machines."
"Its resource usage can be improved."
"Business continuity features need to be added."
"There are some issues with the graphics and some software that is very complex."
"It would be better to have more patches, especially kernel-level updates, live and online so that we can keep the business up and running during this period."
"The solution could use network virtualization."
"The Administration of the Oracle database and the SAP ERP needs improvement."
"I heard that there are big differences between Red Hat eight and seven, but it's still quite difficult for me to judge it. I found it a bit more difficult to manage than version seven, which was much easier. In term of features, though, it is still not yet clear which is better. I have no clear idea of which features need to be changed at the moment."
"Configuring the network interfaces is much better in Ubuntu and should be improved."
"It lags behind in that you need to go to something like Fedora to get all the extra bells and whistles."
"In comparison to VMware, this solution isn't as stable. We're testing it right now, and we're not trusting the stability of the product."
"The support is tricky in a few places. We're facing some challenges within Malaysia where we don't really have the system integrators available who can provide extended support. When we need personnel on-site, we can't get them."
"This solution is an open-source, free platform with paid support."
"It is free for everyone."
"The price is fair compared to others. But in our local market, it's a problem to get budget approval from management. That's why they are trying to get those products so we can give them the price benefit. But if you consider the international market or other products, it's sometimes better than their price."
"This is an open-source solution."
"I would say the price is acceptable."
"We are using the free version of Red Hat."
"I believe we pay on a yearly basis."
"We buy a license for commercial use, and we also use the free editions."
"We have to pay extra for vulnerability and fault tolerance."
"The solution does not require licencing but a subscription is necessary, which is very affordable."
Red Hat Enterprise Virtualization, or RHEV, is a leading open standard enterprise virtualization management solution. This solution supports virtualization of servers and desktops using the same infrastructure and a single easy-to-use interface.
Because RHEV is based on open standards, it is vendor-independent and a lot more cost effective and flexible than proprietary solutions.
KVM is ranked 2nd in Server Virtualization Software with 10 reviews while RHEV is ranked 9th in Server Virtualization Software with 16 reviews. KVM is rated 7.8, while RHEV is rated 8.2. The top reviewer of KVM writes "Stable, easy to set up, and very easy to use". On the other hand, the top reviewer of RHEV writes "The versatility and compatability of this virtualization solution are marred by the lack of availability of local support". KVM is most compared with Oracle VM VirtualBox, Hyper-V, Proxmox VE, Oracle VM and Nutanix AHV, whereas RHEV is most compared with VMware vSphere, Proxmox VE, Oracle VM, Hyper-V and Citrix Hypervisor. See our KVM vs. RHEV report.
