Quotes From Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros
"I think nine out of the ten supercomputers in the world use Linux KVM, so I think that attests to the fact that it is a scalable product.""It is an open ecosystem, and we see there is a benefit in open-source solutions.""I find the density of the product most valuable. It is density that a technologist can just assign page merging. This is what makes KVM one of the important players of the virtualization market.""The initial setup was simple.""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 GUI interface makes the management of KVM easier than ever before."

"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."

Cons
"Technical support is not top-notch.""We would like to have a software lifecycle solution included in this solution. We can handle the software needed for KVM, but also the software that we provide. A lifecycle component would be very beneficial.""The stability of this solution is less than other products in the same category.""The KVM tech support is really bad. They are not very responsive.""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.""Business continuity features need to be added."

More KVM Cons »

"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."

Red Hat
Overview
KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko.

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.
