"If you prefer command-line, there are all kinds of command-line options."
"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."
"It is an open ecosystem, and we see there is a benefit in open-source solutions."
"I like that this is an open-source solution. It is very powerful, and it's easy."
"Scaling the solution is easy. You just have to add more hardware."
"The initial setup was very easy."
"Very cost-effective."
"The tool's most valuable feature is backup. The product makes it easy to manage virtual machines. Other tools require third-party applications like VMware and vSphere. However, KVM doesn't require these applications."
"The stability of the solution is excellent."
"I don't see any challenges in using this product."
"The solution allows for very good virtualization."
"The product offers good stability."
"Vmware vSphere is the benchmark of the visualization market."
"vMotion radically changes the way we think about how we can operate a large infrastructure, and notably, in terms of proactive maintenance."
"The initial setup is easy."
"It is a single pane of glass that lets you access your hosts and VMs."
"The virtual manager and the graphical QEMU for KVM need some improvement."
"I have encountered difficulties in getting the tool's documentation."
"Business continuity features need to be added."
"One problem I have is that it's not very scalable when it comes to resizing the VM disk dimensions. For example, if you have initially set a virtual drive to 10 GB and you want to upgrade it to 15 GB, it's not that easy."
"Monitoring and resolution could be improved."
"Some things are pretty basic, and they could be more robust with more detail."
"Its resource usage can be improved."
"There are some issues with the graphics and some software that is very complex."
"It is expensive."
"The technical support is good. However, it could be more seamless when it comes to chat support and lower response times."
"Reducing the cost of vSphere would be an improvement."
"VMware vSphere could be more secure and well-known to everyone."
"The technical support is poor. We are in Australia, but we do not have the same level of support as the US and Europe."
"Technical support is not that great. It is too slow."
"We stopped using a lot of cloud services. However, I see that VMware has integrated with Amazon Cloud. We will now to have to move everything to the cloud."
"It needs to integrate better between multiple modules."
