Red Hat Bugzilla – Bug 972940
Must reboot nodes which receive kernel with network namespaces.
Last modified: 2013-07-01 16:23:46 EDT
PackStack now deploys a kernel with network namespaces enabled. We need to confirm which nodes get the new kernel (I suspect/assume all networking nodes - L3 agent, L2 agent, DHCP agent, quantum service + by virtue of having at least the L2 agent all compute nodes - but please check with the developers).
For the kernel change to take effect users need to reboot the impacted nodes.
As per mailing list thread we should assume all nodes get the new kernel, thus post deployment all nodes should be rebooted.
