I knew dom0 didn't have net access by design. From workvm, I do have full network access; however, from untrusted (such as untrusted->web browser), I checked in terminal and have no network interfaces. If this is also by design, I suppose I need to RTFM before posting more.
No, "untrusted" VM should have network access...
No even unconfigured interface in the VM? (ifconfig -a)
OK that's just weird. It only had lo, but I decided to restart all the VMs, and now untrusted has eth0 and full network access...
Thanks so much for your assistance... I'm going to updated to R2.
