Hi,
I got 2 interfaces on HE and wanted one for management and the second for VE's (I need several VLANs there).
So I setup HE interfaces like this (fat trimmed)
eth0 Link encap:Ethernet HWaddr 00:21:5e:26:b3:cc
inet addr:126.66.64.151 Bcast:126.66.65.255 Mask:255.255.254.0
eth1 Link encap:Ethernet HWaddr 00:21:5e:26:b3:ce
inet6 addr: fe80::221:5eff:fe26:b3ce/64 Scope:Link
eth1.20 Link encap:Ethernet HWaddr 00:21:5e:26:b3:ce
inet6 addr: fe80::221:5eff:fe26:b3ce/64 Scope:Link
eth1.980 Link encap:Ethernet HWaddr 00:21:5e:26:b3:ce
inet6 addr: fe80::221:5eff:fe26:b3ce/64 Scope:Link
venet0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
(lo, sit0, other VLANs ommitted).
Then I added the vlan to VE like this:
vzctl set 110 --netif_add vlan980 --save
Then I setup the VE settings like this:
(snippet from 110.conf)
IP_ADDRESS="10.0.0.2"
NETIF=" ifname=vlan980,mac=00:18:51:F6:CD:87,host_ifname=veth110.980 ,host_mac=00:18:51:70:E9:7F "
And the problem is I still cannot access the other ip on the network (PING 10.0.0.1 (10.0.0.1) 56(84) bytes of data.
From 10.0.0.2 icmp_seq=1 Destination Host Unreachable)! How to debug this??
BTW. when I assign an address from the VLAN to eth1.980 on HN it works, but VE - its not.
Thanks!

Physical eth1 is connected to trunk port... and it works if I configure it in HE.
What else I can do?

- First of all, make sure that you've configured eth0 interface inside VE properly
Now its like in wiki, previously I've used vconfig to add vlan.
- Then check your routing records inside VE. (make sure that network packets don't leave your VE from venet0 interface.)
Its OK: ip r s
127.0.0.0/8 via 127.0.0.1 dev lo
default dev eth0 scope link
- Use tcpdump utility to find out:
* do the packets leave your VE propely
they leave VE,
* do they reach HN
they reach HE,
* do they leave HN
I don't know, as I don't have a second node and netadmin is on holiday 
http://wiki.openvz.org/VLAN
Excuse me, I try to stay positive, but there is no doc in here, those three lines simply doesn't work, either when I try to move venet interface or create new veth in VE. Maybe because I do have two physical interfaces?
Make sure that firewall in the HN/VE allow your VE to communicate with external nodes.
There is no netfilter setup.
I attach screenlog.

OK, lets try that:
Do I have to configure vlan on physical interface in HE? Do I have to add ip to that interface? I guess answer is yes and no?
So on HE I should have (Gentoo net config):
config_eth0=("126.66.64.151 netmask 255.255.254.0")
routes_eth0=("default via 126.66.65.249")
vlans_eth1="20 980 990"
config_eth1=( "null" )
vconfig_eth1=( "set_name_type DEV_PLUS_VID_NO_PAD" )
config_eth1_980=( "null" )
config_eth1_990=( "null" )

I'm posting tcpdump (its the same on HN as in VE):
11:35:59.979932 IP 10.0.0.3 > 10.0.0.1: ICMP echo request, id 23060, seq 179, length 64
11:36:00.979954 arp who-has 10.0.0.1 tell 10.0.0.3
11:36:00.979959 arp reply 10.0.0.1 is-at 00:18:51:3a:d4:5d
11:36:00.979984 IP 10.0.0.3 > 10.0.0.1: ICMP echo request, id 23060, seq 180, length 64
etc. There is no echo reply.
If I configure devices without vlan in VE I can ping HE and VE each other, I suspect that I could ping also remote interface, but there is no vlan so I cant. Its all about those vlans.
Maybe a step-by-step howto for one interface, multiple vlans?

- enable eth0 inside container
- create vlan interface inside container and issue some settings
well, I have setup eth0.980 5 minutes since installation of the kernel, but it doesn't work. Kernel IP routing table (HE):
Destination Gateway Genmask Flags Metric Ref Use Iface
10.0.0.2 0.0.0.0 255.255.255.255 UH 0 0 0 veth110.0
126.66.64.0 0.0.0.0 255.255.254.0 U 0 0 0 eth0.20
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 126.66.65.249 0.0.0.0 UG 0 0 0 eth0.20
I do all the stuff:
echo 1 > /proc/sys/net/ipv4/conf/veth110.0/forwarding
echo 1 > /proc/sys/net/ipv4/conf/veth110.0/proxy_arp
echo 1 > /proc/sys/net/ipv4/conf/eth0/forwarding
echo 1 > /proc/sys/net/ipv4/conf/eth0/proxy_arp
And I setup vlan the Gentoo way in VE (so its standard Linux way):
vlans_eth0="980"
config_eth0=( "null" )
vconfig_eth0=( "set_name_type DEV_PLUS_VID_NO_PAD" )
config_eth0_980=( "10.0.0.2 netmask 255.255.255.0" )
i get these routes:
10.0.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0.980
127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo
this doesn't work, (Destination Host Unreachable) so packets do not reach HE.
If I do in VE:
ifconfig eth0 0
ip r a default dev eth0
it doesn't work either (sorry! this doesn't work, but ping goes to HE, I forgot to remove previous route!).
I do in VE:
cat /proc/net/vlan/config
VLAN Dev name | VLAN ID
Name-Type: VLAN_NAME_TYPE_RAW_PLUS_VID_NO_PAD
eth0.980 | 980 | eth0
I do in HE:
cat /proc/net/vlan/config
VLAN Dev name | VLAN ID
Name-Type: VLAN_NAME_TYPE_RAW_PLUS_VID_NO_PAD
eth0.20 | 20 | eth0
Its ok, because I'm using vlan 20 for accessing the HE.
I'm loosing the second day on this....

OK, partly works (first vlan i VE works ok).
Now I'm trying to add second VLAN to veth device and it goes ok, but packets are not going back to VE. Why?
In VE 130 I've got two vlans added:
eth0.20 Link encap:Ethernet HWaddr 00:18:51:DB:4E:F2
inet addr:126.66.64.158
eth1.980 Link encap:Ethernet HWaddr 00:18:51:05:AF:37
inet addr:10.0.0.5 Bcast:10.0.0.255 Mask:255.255.255.0
Routes are set OK iv VE:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.0.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
126.66.64.0 0.0.0.0 255.255.254.0 U 0 0 0 eth0
127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo
And routes in HN aore set OK:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.0.0.5 0.0.0.0 255.255.255.255 UH 0 0 0 veth130.0

10.0.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0.990
126.66.64.0 0.0.0.0 255.255.254.0 U 0 0 0 eth0.20
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 126.66.65.249 0.0.0.0 UG 0 0 0 eth0.20
Packets goes fine to HN, but not going back (tcpdump outpup from HN):
15:08:32.501126 IP 126.66.64.158 > 10.0.0.1: ICMP echo request, id 45655, seq 14, length 64
Any ideas how to define source ip on VE?
BTW: I can ping interface in vlan on HN (ping 10.0.0.254 issued in VE is ok, but to 10.0.0.1 - which is gateway - its not working). Ping to 10.0.0.1 from HN - it works.

well, I understand that, that is why I obssesically did set routes through vlan interfaces (and it didn't work).
If I set like you say now I got:
