Open Stack

Hi Adhi,

Do you use devstack to deploy XenServer + Kilo or manually?
Current Kilo release does not support XenServer + Neutron security group, because security group is implemented via iptables on Linux bridge, however, there is no Linux bridge created when booting a new instance.
But we now have a new fix to support neutron security group, we have tested that it can work, this will be implemented as a blue print https://review.openstack.org/#/c/251271/
So, if you want to use neutron security group in Kilo, you should add some patch for your code and also please make the configurations as below:


1.       In nova.conf, two configurations should be set
[DEFAULT]
firewall_driver = nova.virt.firewall.NoopFirewallDriver

security_group_api=neutron


[xenserver]
ovs_integration_bridge =
vif_driver = nova.virt.xenapi.vif.XenAPIOpenVswitchDriver

                If you don't know how to configure ovs_integration_bridge, then you can refer this blog https://www.citrix.com/blogs/2015/11/30/integrating-xenserver-rdo-and-neutron/


2.       In neutron,  check configurations ml2_conf.ini in compute node which is used for neutron L2 agent

[agent]

minimize_polling = False

root_helper_daemon =

root_helper = /usr/local/bin/neutron-rootwrap-xen-dom0 /etc/neutron/rootwrap.conf



[ovs]

integration_bridge =

bridge_mappings =

                Also for ovs configuration items, if you don't clear on how to configure them, refer the blog


3.       In neutron, check configurations /etc/neutron/rootwrap.conf in compute node

[xenapi]

# XenAPI configuration is only required by the L2 agent if it is to

# target a XenServer/XCP compute host's dom0.

xenapi_connection_url=

xenapi_connection_username=

xenapi_connection_password=

Subject: [Openstack] Security Groups Can't Apply in Kilo with Neutron & XenServer

Hi all,

I had Openstack Kilo installed on my lab, for Compute Hypervisor I use XenServer 6.5, and networking Using Neutron OVS. For Controller, Network, and Compute node I'm using Ubuntu 14.04.

My problem was Security Groups rules doesn't applied to the instance that created. For example, there is no rule for SSH port 22 in security group i defined to the instance, but instance with floating IP able to login by ssh from external network.

I've already add this option on my nova.conf

firewall_driver=nova.virt.xenapi.firewall.Dom0IptablesFirewallDriver

and also defined firewall_driver on my ml2_conf.ini at Controller, Network, and Compute node

[ovs]
enable_security_group = True
enable_ipset = True
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver

can somebody help me with this problem ?
