Which OS are you running on top of ESXi? I tought this software was used only in large server farms where hardware abstraction is desired...
Nothing fancy, yet. Mostly console based server version of Ubuntu, a sandbox for my firewall to test new version. But with the hardware passthrough I want to see if I can get windows 7 or 8 and maybe even OSX running under ESXi. OSX might not work; would be a virtual hackintosh. I'm sure it's prevented.
I could use the VMWare server version but that require a host system; which I did before. The free ESXi is right now more a learning. And hey, it looks really nice to manage virtual machines from my iPad. VMware Labs have a virtual appliance which allows that.
