We have a cloud server, and we are trying to install Cast Iron Hypervisor Edition on that server. The could server is a SUSE Linux virtual machine. I know in order to install Cast Iron Hypervisor Edition, we need to install ESXi first. Here is our problem, how can we install ESXi on a cloud server. It seems to me it is not feasible to install ESXi on top of a virtual machine, as the virtual machine doesn't have any control over physical machine. Thanks in advance.
