Anthony =2C

Unfortunately= =2C I dropped instance running XEN . In a couple of days=2C
I will repro= duce environment and send /var/log/xen/xen-hotplug.log to you.
Regardin= g Libvirt version=2C =3B I also tested driver with =3B libvirt 1.2.= 14 =2C manual build
via =3B libvirt-1.2.14.tar.gz ball =3B and u= pgrade on Ubuntu 14.04.2 after stack.sh =3B completion.
I got same e= rror in =3B libxl-driver.log

Thank you.

>=3B Hi Boris=2C
= >=3B
>=3B from the look at the bug 1439645=2C it looks like your ar= e using Neutron for
>=3B the network and this probably were things goe= s wrong. I think there is a
>=3B compatibility issue between Neutron a= nd the script
>=3B /etc/xen/scripts/vif-bridge from the XenProject.>=3B
>=3B Can you look into /var/log/xen/xen-hotplug.log ? There i= s maybe an error
