Likelihood to Recommend	Kernel-based Virtual Machine is very well suited when one needs a single-node virtualization host or needs to build a complex demo setting on their own notebook (e.g. when demonstrating solutions to a customer). Incentivized Valentin Höbel Senior Consultant IT Infrastructure Read full review	Red Hat Virtualization is suitable for small implementation and hosting VMs. However, when you start asking for additional features or enhancements, the engineering team is not the flexible as other engineering teams in Red Hat. It is very likely they will not accept adding features or in the best case. They wouldn't commit to a plan when it is possible to be available. Incentivized Verified User Anonymous Read full review
Pros	Lightweight built-in implementation for all *nix based OS. Easy to deploy and manage VMs. Freeware (is you are using a free OS). Incentivized Verified User Anonymous Read full review	RHV issues/bugs can be reported via Bugzilla to RH support. The service is great and typically responds soon. Red Hat distribution integration is seamless as it is integrated into the kernel. OpenStack support enables more customized VM templates and network configuration control. Incentivized Verified User Anonymous Read full review
Cons	KVM itself doesn't ship with a management interface KVM itself is a bit complicated to handle KVM needs Qemu to virtualize Windows guests Incentivized Valentin Höbel Senior Consultant IT Infrastructure Read full review	Documentation of RHEV needs more improvement. RHEV GUI needs a lot of improvements in some versions of RHEV, GUI will not work properly (shows incorrect details of VM ). Need fast rollout of patch releases. Need good linux Knowledge to manage the RHEVM. Incentivized NS Naveen Sharma Consultant Read full review
Usability	It does the job and stays out of the way. The specifics of usability relies on the implementation, but with things like Icarus and libvirt, things are standardizing nicely. Incentivized Verified User Anonymous Read full review	No answers on this topic
