Yes, I can confirm the output: root@hp3:~# xenstore-ls /local/domain/0/libxl disable_udev = "1" > I've tried to follow the guide, and install OpenStack on Ubuntu 14.04 but I > can not reproduce this.

Okay thanks, I think it's more likely that I may have missed something since it doesn't work here :) > 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. I removed the exit line and added the ip link command to the rename_vif() function, however, I then receive the same initial error and the instance fails to boot: libxl: error: libxl_exec.c:118:libxl_report_child_exitstatus: /etc/xen/scripts/vif-bridge online [-1] exited with error status 1 libxl: error: libxl_device.c:1085:device_hotplug_child_death_cb: script: ip link set vif4.0 name tap90f11177-24 failed libxl: debug: libxl_event.c:618:libxl__ev_xswatch_deregister: watch w=0x7f37c800a050: deregister unregistered libxl: error: libxl_create.c:1226:domcreate_attach_vtpms: unable to add nic devices Thanks again for helping work through this, Geoffrey ----- Original Message ----- > From: "Anthony PERARD" <anthony.per...@citrix.com> > To: "Geoffrey Tran" <gt...@isi.edu> > Cc: openstack@lists.openstack.org > Sent: Friday, July 24, 2015 8:24:52 AM > Subject: Re: [Openstack] Spawning Issue with Juno, Neutron, Xen and Libvirt > > On Thu, Jul 23, 2015 at 09:20:13PM -0400, Geoffrey Tran wrote: > > Hi Anthony, > > > > > Ok, let's debug that further.
