LTSP / DHCP problem with 13.10-beta1 on VirtualBox

[XIA IT Support]

I am currently trying to test an edubuntu setup in virtual box, with a 
view of setting up properly in a month or so.

However I can't get the clients to boot of the LTSP server, it keeps 
telling me that it doesn't get any DHCP offers. I have done a lot of 
googling and tried all kinds of things. One of the things I keep coming 
across is to run:

sudo service isc-dhcp-server restart

however when I do that it always gives me the following message in the logs:

Can't bind to dhcp address: Address already in use

When I check out port  67 and 68 they are being used by dnsmasq. Am I 
doing something wrong here or is there a problem with my installation?

Any help would be greatly appreciated.
