This interface should be DOWN, since the vif-bridge script is responsible
to configure it and set it UP. And I don't see what could change its state.

Could you run the following command after you tried to start a guest?

$ xenstore-ls /local/domain/0/libxl
disable_udev = "1"

We should at least have disable_udev in the output.

I've tried to follow the guide, and install OpenStack on Ubuntu 14.04 but I
can not reproduce this. I've stop after installing neutron, and try to
start a guest. I may have miss something.


Otherwise, to work arround this bug we could modify the script to set down
the interface before trying to rename it:
In /etc/xen/scripts/vif-common.sh, search the function rename_vif() and add
in the begining this:
  ip link set "$dev" down
And don't forget to remove the "exit 0" in /etc/xen/scripts/vif-bridge that
we've added earlier.
