Are you asking if FIO can be built or run on the hypervisor itself, like via ssh? I have tried a test before where I statically compiled FIO and copied it to an ESXi server, but I was never able to get any jobs to start. Not sure if the kernel supports the fork() or whatever call FIO uses to spawn the job processes. So, I’m not sure it can be done. ESXi is not a general purpose OS, so it lacks some features.

Is fio supported on vmware esxi 5 and 6 servers? Does anyone have any helpful guides as to how to install it on vmware? I've searched google but could not find any. The only reference to fio+vmware is Disable libaio for ESXi build - bug#80 Thank you in advance. Regards, Eliezer
