I know it's old news but you can access the ESXi console by using this unsupported method :
- reach to your ESXi over KVMoverIP or just console and press Alt-F1
- then type "UNSUPPORTED" and press <enter>
- login with your root login and password
- and you can do your thing ... or enable SSH in the next steps
- Edit the inetd.conf file by typing "vi /etc/inetd.conf"
- remove the # in front of the SSH line
- reboot your ESXi server (or kill the inetd process and start it again)
