Most likely you didn't set up DNS on the Virtual machine.
You will need to add dns to the hosts line in /etc/nsswitch.conf
and add /etc/resolv.conf with "nameserver <ip address of your dns server>" as contents.
/etc/nsswitch.conf
Code:
...
hosts: files dns
...
/etc/resolv.conf
Code:
...
nameserver 192.168.1.3
...
