"This solution is open source and easy to configure."
"If you prefer command-line, there are all kinds of command-line options."
"The GUI interface makes the management of KVM easier than ever before."
"Good screen and keyboard sharing feature."
"I like that it's easy to manage. It's also more powerful when it comes to security than others. That point of view is the one consideration. The other consideration is that it's cost-effective."
"Very cost-effective."
"It is easy to use, stable, and flexible. It is a pretty mature product, and it is faster than VirtualBox."
"KVM is stable."
"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."
"There aren't any bugs on the solution."
"It is very stable."
"It is easy to deal with when comes to application migration and its compatibility with the multiple component applications."
"The price is the solution's most valuable aspect. It's much cheaper than, for example, VMware."
"The solution is overall very good with all the facilities. It is user friendly, easy to configure, has documentation, and support is available."
"What they provide is way beyond the essential requirements of customers."
"Stability and speed are the most valuable aspects."
"Technical support could be better. In the next release, I would like to see an improved user interface and dashboard. This type of improvement will make it easy or help our engineers understand the solution from a requirement point of view."
"Lacks high availability across clusters as well as support for Apache CloudStack."
"There are some issues with the graphics and some software that is very complex."
"In our setup, we do not have any dashboards or orchestration, and it is hard to manage. We have 25 gig network cards, but the software driver we have only supported 10 gigs."
"Monitoring and resolution 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."
"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."
"It lags behind in that you need to go to something like Fedora to get all the extra bells and whistles."
"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."
"The documentation is not as good as it should be."
"Red Hat by itself is not scalable. But you can have third party add-ons like Ceph to make it massively scalable."
"We'd like it if it would be possible on Red Hat Virtualization to possibly connect two or three VMs to the same disk."
"We hope that Red Hat can produce a paradigm edition. We are looking for paradigm computing and paradigm storage. Its scalability can be improved. It is not easy to scale, and we hope that Red Hat can provide a more scalable system. They should also provide local service and support. Our customers are looking for a good software vendor to provide professional services."
"The availability of technical expertise with the solution may be limited in some areas."
