Indeed !
that was that last setting missing:
prlctl set MyCT11 --ifname eth0 --network vlan11
now vlans works fine
Just note that I had to add NM_CONTROLLED="no" to all mi ifcfg-xxx
definition files, otherwise network restart failed to start them

Dear Jehan,
Virtuozzo 7 have nice documentaion on docs.virtuozzo.com
http://docs.virtuozzo.com/virtuozzo_7_users_guide/managing-network/configuring-virtual-machines-and-containers-in-bridged-mode.html?highlight=bridge
in your case you need to bind container interface to newly-created bridge by
using follwing command:
prlctl set MyCT11 --ifname eth0 --network vlan11
Thank you,
Vasily Averin

I found a method to configure bridge and vlan based on RHEL docs :
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Networking_Guide/sec-Network_Bridging_Using_the_Command_Line_Interface.html
in order not to mess with current config automatically configured by virtuozzo7
installer on em1 and em2 with repective bridges br0 en br1, I plugged a 3rd
interface on the server (fiber) p2p2 :
[network-scripts]# cat ifcfg-p2p2
TYPE=Ethernet
BOOTPROTO=none
NAME=p2p2
UUID=9188d131-21b1-4ee9-8205-c893b4a4fc44
DEVICE=p2p2
ONBOOT=yes
then the associated subinterface for vlan11 as described in RHEL7 doc
# cat ifcfg-p2p2*.11*
DEVICE=p2p2.11
BOOTPROTO=none
ONBOOT=yes
VLAN=yes
BRIDGE="br11"
and finally the bridge for that vlan
# cat ifcfg-br11
DEVICE="br11"
NAME="p2p2.11"
ONBOOT=yes
NETBOOT=yes
IPV6INIT=yes
BOOTPROTO=dhcp
TYPE="Bridge"
DELAY="2"
STP="off"
# ip -d link show p2p2.11
41: p2p2.11@p2p2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue
master br11 state UP mode DEFAULT
link/ether f4:e9:d4:91:c4:33 brd ff:ff:ff:ff:ff:ff promiscuity 1
vlan protocol 802.1Q id 11 <REORDER_HDR> addrgenmode none
# ip -d link show br11
42: br11: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP
mode DEFAULT
link/ether f4:e9:d4:91:c4:33 brd ff:ff:ff:ff:ff:ff promiscuity 0
bridge addrgenmode none
Now I can add my virtual network attached to the p2p2.11 interface (or should I
have chosed br11 !?)
# prlsrvctl net add vlan11 --type bridged --ifname p2p2.11
# prlsrvctl net list
Network ID Type Bound To Bridge Slave interfaces
Bridged bridged em2 br1
Host-Only host-only virbr0
vlan11 bridged p2p2.11 br11
# brctl show

br0 8000.14187769840a yes em1
br1 8000.14187769840b no em2
br11 8000.f4e9d495c432 no p2p2.11
host-routed 8000.000000000000 no
virbr0 8000.52540064dd31 no virbr0-nic
create a container MyCT11
# prlctl create MyCT11 --vmtype ct
...
Processing metadata for centos-7-x86_64
...The Container has been successfully created.
now I add an interface to my CT so that it will be in vlan11
# prlctl set MyCT11 --netif_add eth0
# prlctl set MyCT11 --ifname eth0 --ipadd 192.168.11.10/24
# prlctl set MyCT11 --ifname eth0 --gw 192.168.11.1
entering the CT an pinging the gateway unfortunatly fails
CT-bad098d8 /# ping 192.168.11.1
PING 192.168.11.1 (192.168.11.1) 56(84) bytes of data.
^C
--- 192.168.11.1 ping statistics ---
3 packets transmitted, 0 received, 100% packet loss, time 1999ms
the pb seems that that new CT seems to be attached to an other bridge
# prlsrvctl net list
Network ID Type Bound To Bridge Slave interfaces
Bridged bridged em2 *br1 * *veth4250fe85 *
Host-Only host-only virbr0
vlan11 bridged p2p2.11 br11
not to vlan11 network on br11
I guess I missed something , where did I went wrong ?
anyone has a full scenario to enable vlan through bridge mode in CT (and VM) ?

hello
based on
https://docs.openvz.org/openvz_users_guide.webhelp/_configuring_virtual_machines_and_containers_in_bridged_mode.html
it is not clear to me how to create virtual networks associated to vlans ?
On a fresly installed Virtuozzo Linux release 7.2 (3515) on a host with 2
activated interfaces (em1 and em2) in trunk mode (cisco terminology switchport
trunk, allowed vlan 10,11,12, native 10) I cannot find out how to create
networks dedicated to a vlan
I tried :
# prlsrvctl net add vlan11 --type bridged --ifname em2
Failed to add Virtual Network vlan11: This network adapter is already in use.
Please select another network adapter and try again.
I suspect that because em2 is already bridge to br1, it cannot be bridged
anymore ?
Or should I create a /etc/sysconfig/network-scripts/ifcfg-em2.11 to have a
interface dedicated to vlan11 :
# cat ifcfg-em2.11
DEVICE=em2.11
ONBOOT=yes
TYPE=Ethernet
BOOTPROTO=none
VLAN=yes
an then try to: /prlsrvctl net add vlan11 --type bridged --ifname em2.11/ ?
unfortunatly after /systemctl restart network/ , system complains with :
Bringing up interface em2.11: Error: Connection activation failed: No suitable
device found for this connection.
as anymone succeed in configuring CT and VM attached to vlan (in bridge mode as
I want full feature network with multicast/broacast) ?
Thanks .
PS : few more information of the actual network config on the system :
# ip addr | grep LOWER_UP

it strange that em1 and br0 doesn't show up here !?
