Hello
How can i run esxi 5 vm on linux ?
I've not tried it personally, but the Windows version of VMware Workstation 7/8 can virtualise ESX 5, so I would imagine the linux version of workstation can do the same.
Remembering that ESXi is a bare metal hypervisor and installs directly on to hardware so you can install it on top of linux but as the other poster indicated you can get VMware Workstation for Linux and create a virtual environment to run your ESXi host within a virtual machine
