I also ran into this problem, on 7.10 (desktop). I already had the mac address set in the guest configuration file, but networking didn't work in the guest. I finally got it to work by applying Todd Deshane's workaround of removing network-manager and adding
auto eth0 iface eth0 inet dhcp to /etc/network/interfaces. -- domU fails to get network connection https://bugs.launchpad.net/bugs/150805 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
