Something wrong with Europa VM --- super slow for port scanning etc

Something wrong with Europa VM.

It took me a record 12223.31 seconds (203 minutes) to run this simple nmap scan and still not getting the usual full results:

	nmap -sS -sV -T4 -p- -sC -Pn -A 10.10.10.22

In the past I get full nmap results with other VMs in a few minutes. For example , 330 seconds for Tenten nmap scan which I have just run.

Please enlighten. Thanks.
