*SOLVED* Routable IP's [message #4688]

From HOST I have added a routable IP by:

$vzctl set VEID --ipadd ###.###.###.### --save

Restarted VE

From inside VE the proper IP is there for venet0:0:
-bash-3.00# ifconfig
<---- snipped lo ---->
venet0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
inet addr:127.0.0.1 P-t-P:127.0.0.1 Bcast:0.0.0.0 Mask:255.255.255.255
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)

venet0:0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
inet addr:###.###.###.### P-t-P:###.###.###.### Bcast:###.###.###.### Mask:255.255.255.255
UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1

From HOST ifconfig venet0:
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:3 errors:0 dropped:0 overruns:0 frame:0
TX packets:3 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:252 (252.0 b) TX bytes:252 (252.0 b)

Do I need to map the routable IP to eth0 or manually add another venet interface for the routable IP that is set for the VE?

The symptom is I am unable to reach the VE outside of the HOST. I can trace to the box but then it dies without a response from the box. If I map to eth0:1 it pings/traces but does not route the traffic to the VE it is set to.

Thanks for any help on clearing this up.

What template you use?

And, it would be better if you show your ifconfig without ### and route -n after adding ip by vzctl.

Template - centos-4-i386-minimal

# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
72.18.###.### 0.0.0.0 255.255.255.255 UH 0 0 0 venet0
72.18.###.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
0.0.0.0 72.18.###.1 0.0.0.0 UG 0 0 0 eth0

This being a very new install, I prefer not publishing my IP

I can confirm that venet0 matched the IP I have in the VEID.conf. If it is needed, then I would prefer PMing when needed.
