Thanks everyone for helping out, it's working!!
What I did:
- removed all previous installs
- downloaded new install for IO analyzer
- deployed ovf as described in pdf
- left everything default (dhcp)
- Disabled ESX hosts lockdown mode and enabled SSH
- logged in webinterface IO Analyzer, added ESX hosts with Chrome browser
- Voila, able to run tests!
What my issue was? I can't say
