Hi people.
Firstly, thanks for OpenVZ. I really appreciate the hard work put
into the community aspects. Very impressed to see how far OpenVZ has
come since it's launch.
I have a VE that I've added 2 IP's to. Both on different networks.
This was by using the default --ipadd option of vzctl.
eg.
10.0.0.9
192.168.1.9
On the Host I have set up Source based routing according to the
example on the page:
http://gflug.net/~mdmartz/index.php/Linux:Network:DualNetRou teHack
eg.
eth0 - 10.0.0.5 - Default route --> 10.0.0.1
eth1 - 192.168.1.5 - Default route --> 191.168.1.1
On the Host, I am able to ping both default routes. On the VE, I can
only ping the first default gateway, 10.0.0.1. I'm unable to ping
192.168.1.1.
Is it possible to have 2 interfaces on a VE, each using a separate
route? Feel free to just outline the general concept of what I have
to do :). Any help would be greatly appreciated.
Thanks,
Julian

Hello,
Can you, please, try to ping from VE using following command:
ping 192.168.1.1 -I 192.168.1.9
The thing is that ping takes the first IP address from interface as default.

That works for me.
Doing more testing, when I take out the global default route on the
Host (10.0.0.1) I can't ping 10.0.0.x from the VE. It's as if the VE
inherits only the global default route from the Host. However, when I
take out the global default route, I am able to ping external IPs on
the internet.
The VE automatically specifies its default gateway as 192.0.2.1
(through /etc/sysconfig/network). I'm not sure if that's related.

Can you, please, send your ip configuration and route tables on host node and
in VE (ip a ls, ip r ls).
Regards,
Andrey
