Q:

Why doesn't bridged networking work on VMware Server 2.0 w/ Ubuntu 9.04?

I'm installing VMware Server 2.0 on an Ubuntu 9.04 system. I have an Ubuntu 9.04 guest with Bridged network interface configured.

There is actually a bug filed on Launchpad about this issue, and a user submitted a patch to a similar query on Ubuntu Forums. Patching the vmware-config.pl as described worked for me. Here's the patch:
