I still cannot run vlan on my VEs :-(
as I cannot find a easy way with venet , I am now trying with veth.
I follow docs:
http://wiki.openvz.org/VLAN and http://wiki.openvz.org/Virtual_Ethernet_device

regarding 1st doc, I set from the HN a veth in vlan 21 for my VE (21233)

[r...@cuzco ~]# vzctl set 21233 --netif_add eth0.21 --save
Configure veth devices: veth21233.0
Saved parameters for CT 21233

I also already do have a eth0.21 interface on the HN for vlan21

[r...@cuzco ~]# ifconfig eth0.21
eth0.21   Link encap:Ethernet  HWaddr B8:AC:6F:83:CC:9E
         adr inet6: fe80::baac:6fff:fe83:cc9e/64 Scope:Lien

         collisions:0 lg file transmission:0
         RX bytes:77972548 (74.3 MiB)  TX bytes:3820 (3.7 KiB)

I hope/supose there's no conflict name between eth0.21 on HN an eth0.21 on VE !?

anyway, on the HN I correctly ping vlan21 router
[r...@cuzco ~]# ping 157.159.21.1
PING 157.159.21.1 (157.159.21.1) 56(84) bytes of data.
64 bytes from 157.159.21.1: icmp_seq=1 ttl=255 time=0.771 ms

On VE I manually configure network:

[r...@monitor /]# ifconfig eth0.21 0
[r...@monitor /]# ip addr add 157.159.21.233/24 dev eth0.21
[r...@monitor /]# ip route add default dev eth0.21

it ping itself:
[r...@monitor /]# ping 157.159.21.233
PING 157.159.21.233 (157.159.21.233) 56(84) bytes of data.
64 bytes from 157.159.21.233: icmp_seq=1 ttl=64 time=0.020 ms

but not the router on vlan 21 :-( :

[r...@monitor /]# ping 157.159.21.1
PING 157.159.21.1 (157.159.21.1) 56(84) bytes of data.
From 157.159.21.233 icmp_seq=2 Destination Host Unreachable

Did I miss something ?
is there a need to add a route for the VE on the HN ? I tried without success
# ip route add 157.159.21.233 dev veth21233.0
RTNETLINK answers: No such device
although there is a veth21233.0 device !
[r...@cuzco network-scripts]# ifconfig veth21233.0

I saw lot of post about creating bridges ... do I need a bridge something somewhere ?
please help .

Thanks .

After all, I am wondering if it possible to run multiple vlan with venet ?
should I consider using veth instead of venet ?
I wanted to run it on venet because it prevent me to find a Mac address for each of my VEs , but if it's impossible, I might consider using veth. Any pros and cons between veth/venet for vlan use ?

for documentation  on this subject I only found one based on veth:

http://wiki.openvz.org/VLAN
http://ckdake.com/content/2008/vlans-in-openvz.html
http://en.gentoo-wiki.com/wiki/OpenVZ_VLAN

any others ?

Thanks .

hello

I created 2 VEs on HN that are on different vlans
HN is on "native" vlan 22, VE1 is on vlan 10 and VE2 on vlan 21

[r...@cuzco ~]# vzlist -a
      CTID      NPROC STATUS    IP_ADDR         HOSTNAME
       101         16 running   -               -
10222 12 running 157.159.10.222 moodle2010.it-sudparis.eu
     21233         12 running   157.159.21.233  monitor.it-sudparis.eu

my problem is that VEs cannot get out of their own vlan :-(
Example, from VE1 on vlan10 I cannot ping Vlan21 addresses (21.1 and 10.1 is the cisco switch/router that routes ip between vlans)


[r...@cuzco ~]# vzctl enter 10222
entered into CT 10222

ping OK on it's own vlan, but not on the other one:

[r...@moodle2010 /]
$ ping 157.159.21.1
PING 157.159.21.1 (157.159.21.1) 56(84) bytes of data.

--- 157.159.21.1 ping statistics ---

did I missed somthing ?

here's some more information about network parameters:
