[ovs-discuss] 答复: can't remove openvswitch.ko with "modprobe -r openvswitch "

2016-10-10 Thread xiongzhiwei 
Hi Justin, Thanks for your help.

Yes, I have checked the dependencies of openvswitch.ko, the results as below:

[root@localhost bai_ovs_2.5]# lsmod | grep openvswitch
openvswitch   258935  1 
nf_defrag_ipv6 34651  1 openvswitch
gre13808  1 openvswitch
nf_defrag_ipv4 12729  2 openvswitch,nf_conntrack_ipv4
nf_conntrack  101024  5 
openvswitch,nf_nat,nf_nat_ipv4,iptable_nat,nf_conntrack_ipv4
libcrc32c  12644  3 xfs,btrfs,openvswitch
[root@localhost bai_ovs_2.5]# modprobe --show-depends openvswitch
insmod /lib/modules/3.10.0-123.el7.x86_64/kernel/lib/libcrc32c.ko 
insmod /lib/modules/3.10.0-123.el7.x86_64/kernel/net/ipv4/gre.ko 
insmod /lib/modules/3.10.0-123.el7.x86_64/kernel/net/netfilter/nf_conntrack.ko 
insmod 
/lib/modules/3.10.0-123.el7.x86_64/kernel/net/ipv4/netfilter/nf_defrag_ipv4.ko 
insmod 
/lib/modules/3.10.0-123.el7.x86_64/kernel/net/ipv6/netfilter/nf_defrag_ipv6.ko 
insmod /lib/modules/3.10.0-123.el7.x86_64/extra/openvswitch.ko

I have tried to rmmod these dependancies, but still faild. The error is shown 
"modprobe: FATAL: Module *** is in use” same as Openvswitch kernel model. 

I have tested uninstallation would be faild once I added an ovs bridge witch 
command "ovs-vsctl add-br br0", even though I have killed ovs-vswitchd and 
ovsdb procedure.
If I remove all ovs bridges with command "ovs-vsctl del-br", the uninstallation 
still faild.

I don't know what happened.

Thanks

You might check the log files.  You might also check "lsmod" and see if there's 
any dependency on it.

[ovs-discuss] [ovn][networking-sfc]

2016-10-10 Thread Murali R 
Networking-sfc and ovn install guide says "port_security" must be enabled
when enabling networkin-sfc  (networking-ovn/doc/source/install.rst -- line
165)

In my use cases it gets too complicated if I use port-security, so was
disabling it.

Please let me know if there is any hard requirement that this MUST be
enabled in Neutron?

Hi,
but for those unable to attend any chance you are planning on grabbing the 
discussions on video and make the few slides available (I expect this to be 
more talk and less slides thou)?
Maybe and I know people hate the word, but someone writing summarized minutes

[ovs-discuss] Access all OVS VLANs via VPN without OVS tunnels

2016-10-10 Thread s.maksy...@emw.hs-anhalt.de 
Hi everyone,

I am fighting long time with the following problem:

+-+
|  Server |
| |
+---+   | |
|   Laptop  |   | Bridge  |
|   |   ++-+-++
+---+---+   |  vpn   |  vme|  vme.10 | vnet1  |  
+--+
|  vme.10   |   vme |   || |  tag=10 | tag=10 |  |  
Virtual |
192.168.10.2|192.168.0.2+--->| | |<--+  
machine |
+---+---+   ++-+-++  
+--+

  vme.10: Linux VLAN with id=10 vme: ovs bridge  
[192.168.0.1]
  vme:VPN tap   vme.10:  port for VLAN 10 access 
[192.168.10.200]
vpn: port used by VPN server []
vnet1:   auto-created by libvirt []

$ ovs-vsctl show
Bridge vme
Port "vnet1"

Port vpn
Interface vpn
type: internal
Port "vme.10"
tag: 10
Interface "vme.10"
type: internal
Port vme
Interface vme
type: internal


I want my laptop to be able to access both 192.168.0.1 and 192.168.10.200, 
which are untagged and tagged accordingly, but I don't need Open vSwitch on it 
to establish GRE tunnels, etc.

I have tried to set trunk on vpn interface:
$ ovs-vsctl set port vpn trunk=10,20 vlan_mode=native-untagged

but it doesn't help, I still can ping  192.168.0.1, but not 192.168.10.200. 
Only when I set a tag for vpn:
$ ovs-vsctl set port vpn tag=10

then I can ping 192.168.10.200, but lose a connection to 192.168.0.1, as well.

So, how can I have both "networks" accessible via VPN connection?

NOTE: while writing this letter, I had obtained that VLAN device on my laptop 
doesn't work at all with ovs. I mean it works only via untagged interface:

$ ping -I vme 192.168.10.200

...

PING 192.168.10.200 (192.168.10.200) from 192.168.10.100 vme.10: 56(84) bytes 
of data.

$ ip addr

This implies another question: does OVS support native Linux VLAN tags?


Thanks in advance!

[ovs-discuss] remote syslog on ovs

I am currently trying to configure remote logging.
I want to  forward my log to a remote syslog server.
I have seen that it is possible to configure syslog as a log target using
ovs-apctl. But where can i specify a remote syslog server?
