Re: [ovs-discuss] Openvswitch with LXC
Thank you Rayomond,
I followed these steps:
1) sudo lxc-start -n c2 -d --logfile=logs
2) ovs-vsctl add-br switch0
ip add add 192.168.100.1/24 dev switch0
I have these two scripts:
BRIDGE=switch0 ovs-vsctl --may-exist add-br $BRIDGE ovs-vsctl --if-exists
del-port $BRIDGE $5 ovs-vsctl --may-exist add-port $BRIDGE $5
# cat /etc/lxc/ifdown #!/bin/bash ovsBr=switch0 ovs-vsctl --if-exists
del-port ${ovsBr} $5
I managed to attach the lxc interface to the ovs-bridge
sudo ovs-vsctl show
8cd3e1a6-eaa9-4341-b5c8-677e381c8306 Bridge switch0 Port vethlQXvGc
Interface vethlQXvGc Port switch0 Interface switch0 type: internal
ovs_version: "2.13.1"
The problem now is that the container did not take IP. P.S I only have one
physical interface so I did not bind it with the bridge.

Re: [ovs-discuss] Openvswitch with LXC
Pretty simple:
1) read the man page on lxc.container.conf
2) build one or two interface up/down files
Don't guarantee this works without a bit of extra massaging, but should
be enough to get started:
# cat /etc/lxc/scripts/ovs.port.up.sh
#!/bin/bash
logger "lxc_name=${LXC_NAME}"
logger "lxc_config=${LXC_CONFIG_FILE}"
logger "values = $1 $2 $3 $4 $5"
logger "vlan=${VLAN} $5"
BRIDGE=ovsbr0
ovs-vsctl --may-exist add-br $BRIDGE
ovs-vsctl --may-exist add-port $BRIDGE $5
if [ "$VLAN" != "" ]; then
ovs-vsctl set port $5 tag=$VLAN
fi

[ovs-discuss] dp_hash algorithm works incorretly when tcp retransmit
We meet a problem that same tcp session selects different ovs group bucket when in tcp retransmition, and we can easily reproduce this phenomenon. After some code research, we found that when tcp retransmit, it may call function sk_rethink_txhash(), and this function makes skb->hash changed, hence different ovs group bucket selected. anyone has good suggestions to fix this problem? ___ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss

It'll be good to unify them, i.e. convert all to rST. Looks like a big chunk of work, though. While we're on this topic, It would be great if you could take a quick look at this patch: http://patchwork.ozlabs.org/project/openvswitch/patch/20210129140305.1392406-1-i.maxim...@ovn.org/ Best regards, Ilya Maximets. ___ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss

I missed that typo during review. I was trying to figure out why we didn't catch this issue in OVS build and I found that we actually have 2 copies of several parts of manpages. One .man file and one .xml file for following docs: lib/common.xml lib/daemon.xml lib/db-ctl-base.xml lib/ssl.xml lib/ssl-bootstrap.xml lib/ssl-peer-ca-cert.xml lib/table.xml lib/vlog.xml lib/unixctl.xml All these files were added to be used in OVN man pages and has no users in OVS code base. We should, probably, generate man pages from these xml files instead of having *.man duplicates to catch this kind of issues. (Writing this down just to highlight the issue and not forget).
