I only use DHCP for my wireless clients (hard allocate IP and hostname based upon ethernet address) and true guests to my network. The bridged method works fine - no bridge on host just normal ethernet - bridged on Virtualbox. As it works I have not moved up to version 4 as yet - probably will when CentOS 6 gets released and I build a new workstation. There are just a few pesky apps that insist on using windows / IE and have no viable open source alternatives that keep me using a WinXP guest. -------------- next part -------------- A non-text attachment was scrubbed...
