Hello,
Today I've installed Juno using official documentation with VXLAN
networking (Host OS is Ubuntu Server 14.04). I have exactly the same
issues with previous installation (GRE). qbr bridge, after tap,
reconstructs the packets. After disabling "bridge-nf-call-iptables" tap
problem is solved and packets go as-is. However, I hit MTU problem in
router namespace again.
I needed to lower the internal leg in router namespace to match VMs MTU
to get ICMP packets working. With this setting, ICMP packets are OK and
any length can be send across the network.
I set MTU of 1400 on both VM and internal leg in router namespace to be
on safe side. The suggested 1452 on the documentation did not work. I
guess it was not small enough for VXLAN overhead.
I tried to test iperf inside VM to router (iperf -c 10.0.0.1), but that
gave me the following kernel error:
-------

I needed to "rmmod bnx2x && modprobe bnx2x" to get the eth working
again. After this failure, I tested simple nc connection inside VM to
router and I hit retransmission issue again. Without any data sent (just
after nc 10.0.0.1 9999), I see the attached retransmission lines. It
seems that it cannot correctly complete three-way handshake?
As a side note, not related with the network issue, I got libvirt error
on Ubuntu Server 14.04 in compute node. The VM was stuck and I couldn't
kill it. The logs on compute note showed the following. The detailed
syslog is attached.
"BUG: soft lockup - CPU#9 stuck for 22s! [qemu-system-x86:8838]"
Searching the error, it was suggested to upgrade the kernel. It seems
that I am having serious issues on Ubuntu Server 14.04 with
3.13.0-44-generic. In other lab environment, we use Fuel deployment on
Ubuntu Server 12.04 LTS with GRE and we didn't have those problems
(retransmission, packet construction, etc). Although GRE has its
performance issues, we can get 1.8-2Gbit link between VMs to network
node on 10Gbit network. I should add that all the physical machines are
same within all environments.
I will try updating the kernel to "linux-image-3.16.0-29-generic", which
is latest in ubuntu repository.
Has anyone tried Juno on Ubuntu Server 14.04 with linux-image-3.16.0-29
(which is the default) or am I the only one having those problems? Any
Ubuntu folks here? Is it possible that ubuntu cloud repository has some
specific patches for openstack, ovs, or other related software?
I am attaching related configuration files used in VXLAN environment.
Regards,
Eren
