Here are some other reasons: * Best support for PCIe passthrough, easily toggle PCIe devices from UI without reboot. * Best networking with virtual distrubuted switches - more intuitive to manage and use * vSAN integration with k8s for block volumes is great, including volume snapshots. Also supports RWX (nfs) volumes * vSphere api is a first class citizen with cloud native tooling such as terraform, ansible and packer. It also has a great golang-based cli via govc. With all that said I actually still experiment with kvm (kubevirt, harvester etc) by running it nested inside esxi which works exactly how you would expect. Much prefer vSphere as the base of my lab though.
