Hello, After making some tests we have found why the virtual network card was not working. It happens when the virtual server has a multi-proc and a bridged network. We have bought Parallels server for its capacity to virtualise a multi-proc. Do someone have a solution? Best regards, Configuration : Macosxserver 10.5.6 2x2.8 Ghz / 10go ram Parallels server Build 3.0.2217.237106 Virtual server : Debian Etch : Linux 2.6.18-6-686 #1 SMP Fri Dec 12 16:48:28 UTC 2008 i686 GNU/Linux
