Public bug reported:

After performing a package update of a deployed Folsom cloud (with
running instances), nova-compute fails to start up with the following
trace back:

This is a nova-network multi_host/libvirt deployment.

nova.conf on the compute node is as follows:

[DEFAULT]
dhcpbridge_flagfile=/etc/nova/nova.conf
dhcpbridge=/usr/bin/nova-dhcpbridge
logdir=/var/log/nova
state_path=/var/lib/nova

libvirt_use_virtio_for_bridges=True

root_helper=sudo nova-rootwrap /etc/nova/rootwrap.conf
verbose=True
ec2_private_dns_show_ip=True
api_paste_config=/etc/nova/api-paste.ini

rbd_user=nova-compute

rbd_pool=nova

This could very well be a config issue, in which case its a packaging
bug, or perhaps a data migration. I know there has been work this cycle
around the libvirt interface drivers
