[Rdo-list] Revisited: Neutron Quickstart, ovs_use_veth and RHEL 6.4.
by Brent Eagles
Hi Thomas,
You may recall a thread started by Perry from earlier this month with
the title "Trying out Neutron Quickstart running into issues with netns
(l2 agent and dhcp agent)" where the DHCP and L3 agents were complaining
of RNETLINK resource busy type of errors when trying to set the MAC
addr. The workaround was to enable ovs_use_veth. I had been stating that
this was a required configuration for some time without knowing the
correct reason why but Maru explained it to us later on, so everything
is great in that respect. However... (there is always a "however", isn't
there?)
One of our team was *not* having this issue. In fact everything has been
working for him for some time and he has never touched that
configuration item. It turns out he was getting updates from the RHEL
6.5 composes build. After we discovered the differences, I downloaded
the kernel and firmware rpms and installed them to a 6.4 VM and I also
could get away without using the ovs_use_veth. We are doing some
additional testing to see just how much works with this kind of setup
(devstack, tempest, etc.). So far, it seems that whatever is changed
between the openstack kernel and the one in the 6.5 composes addresses
the issues that ovs_use_veth works around. Hopefully this info is of
some use to you! I'm going to copy and preserve the current state of my
VM so let me know if there is anything specific you want me to try with
this configuration
Cheers,
Brent
