Earlier, we were using Oracle VM, which was a little better than KVM, especially in terms of user-friendliness and implementation.

I used to use another hypervisor, but licensing just bored me, so I found KVM. It is powerful and open source and it has a very big support community.

I use Oracle Linux Virtual Manager, which is KVM-based, and oVirt console.

We have used VMware and Microsoft Hyper V, among others, and then changed to KVM. I was not happy with Hyper V at all as we didn't want to use any Microsoft domain, and Hyper V needed us to use it. KVM allows us to avoid Microsoft. 

I have worked with VMware before KVM. You need a subscription and license to work with VMware. VMware has features like vMotion and storage vMotion. KVM has the same features as well. The main difference between the two is in licensing costs. 

KVM is a perfect alternative to commercial solutions in the market such as VMware, especially when it comes to stability. In my experience, KVM is more stable than VMware.

I provide other solutions like VMware virtual desktop and ESXi server.

My company has experience with Oracle Linux VM and Oracle VM apart from KVM. KVM and Oracle Linux VM are more stable and flexible compared to other products in the market. My company does not recommend products from KVM's competitors since we have an Oracle-centric environment, and most of the time, we get VMs with Oracle licenses only. Oracle VM will not do anything to improve the product since it can be described as an end-of-life product.

We previously used Red Hat but the Hypervisor is excellent with KVM and more stable.

I have been using VMware, ESXi, and Linux and will continue to use them while I get more experience with KVM.

I didn't previously use a different solution. I just recently got this server.

We were using VMware prior to KVM. It is a very reliable and very strong solution, but it is also very expensive. We are switching to try and reducts cost both in terms of licensing and managing.

I have previously used VMware and KVM is easier to use. However, they both have their strengths depending on their use cases. They are mostly equal. One of VMware's advantages is it has better support.

I used Xen in the past and switched because the customers requested a solution which allows running a guest with its own Kernel. This is also possible with Xen, but not a common use case, though.

We have used Baremetal.

I have used XenServer and VMware, and the performance of KVM is better than these.

When it comes to management, integration, business continuity, and live migration, KVM is lacking features and VMware is better in this area.

We are currently using VMware in our production environment.

We previously used VMware but switched to KVM because it is an open ecosystem and we see there is a benefit in open source solutions.

We previously used VMware. 

I previously used VMware VM VirtualBox and then Workstation Pro. I switched because VMware is not free.
