Could you show the contents of /etc/xen/scripts/vif-bridge? Is it random whether the 10.x.x.x or 216.x.x.x device goes down?
Is it perhaps always the one with the higher or lower mac address? Once this affects a guest, and after a reboot, does it ever re-occur on the same guest? You showed install instruction, but not upgrade instructions. Do you just do a standard do-release-upgrade in the guest? Do you reboot afterward? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/728519 Title: Bridged Guests losing network connectivity under non-ubuntu Xen after upgrade from 8.10 to 10.04 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
