Open Stack

+1 you can’t use the libvirt specific firewall driver with XenAPI

There are some example nova.conf files here that may help:
http://docs.openstack.org/folsom/openstack-compute/admin/content/xenapi-flat-dhcp-networking.html

If you use DevStack, it should have “chosen” the correct firewall driver for you.

Cheers,
John

Your firewall driver in your nova.conf seems to be incorrect


2012-11-21 01:33:47 TRACE nova     self.firewall_driver = fw_class(xenapi_session=self._session)

2012-11-21 01:33:47 TRACE nova   File "/usr/lib/python2.7/dist-packages/nova/virt/libvirt/firewall.py", line 227, in __init__
It's trying to use the libvirt driver.

# grep firewall /etc/nova/nova.conf
firewall_driver=nova.virt.xenapi.firewall.Dom0IptablesFirewallDriver

Good luck with OpenStack!
