Haver you got SSH configured on the host computer to port forward to the servers (Are the virtual hosts in bridged or NAT mode?) - Looks to be bridged.
I would have thought that this could just be someone 'trying' to brute force SSH. It doesn't necessarily mean they have been able to successfully connect from the logs above unless I am missing something.

Have a scroll through you logs for successful/unsuccessful attempts on SSH.
