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 (vWLAN)) 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.
