After assisting someone with troubleshooting networking, I determined that setting 'ovs_use_veth = True' in dhcp_agent.ini and l3_agent.ini breaks Neutron (at least with GRE) on recent versions of CentOS... perhaps because the kernel seems to fully support namespaces. This issue probably also affects Scientific Linux. Can anyone confirm whether recent RHEL kernels fully support namespaces? I would like to clarify this step and similar steps in other sections for all distributions.

<sgordon> Sam-I-Am, so - for RHEL/CentOS 6.4 the stock kernel did not support netns BUT we shipped a patched kernel in RDO
<sgordon> Sam-I-Am, for RHEL/CentOS 6.5 the stock kernel includes netns support
<sgordon> RDO still has a to ship a modified iproute2 though - i believe we couldn't update that in 6.* without breaking our kABI promises
<Sam-I-Am> sgordon: ah ha. i think i did a yum upgrade on a 6.4 box and got the new kernel
<sgordon> but the long and the short of it anyone using RDO Havana/Icehouse should have netns support
<sgordon> by virtue of either the RDO modified kernel (6.4) or the stock kernel (6.5)
<Sam-I-Am> which are the packages the guide references
<sgordon> right
