We do not officially support KVM but have had a few feature requests for it. Similarly we have had a few feature requests for Microsoft Hyper-V and Citrix Xen. I would be interested to hear from the community in the feature request section (Feature Requests (Elite On-Premises)) which hypervisors you have got working and which hypervisors you would want official support for besides VMware.
Wireless and Network Management
For those interested we have started a beta program for a KVM image of vWLAN. See the vWLAN 3.0.1 KVM Beta image and quickstart guide posted under support downloads for Bluesocket vWLAN.
