I have a HN with two physical network interfaces connected to two subnets. I want VE's to have addresses in both subnets. I read through the extensive and confusing wiki article on using private IP's for Hardware Nodes, but it's not clear what I need to do to accomplish what I want.

Can I just have two venet interfaces per VE? If so, are the routing tables taken care of automatically?

I guess what you want is just
vzctl set CTID --ipadd a.b.c.d --ipadd e.f.g.h --save


and that's it. Here a.b.c.d is an IP address from the first subnet, and e.f.g.h is an IP address from the second subnet.

VE is like direct connected and don't need special ip rule to pass the HN.
Imagine a tower and each floor represent a VE machine but all use the same exit or enter to the building. Exit and enter represent the networks adapters.
At least using venet adapter.

P.S. When using 2 ip-s or more inside VE don't forget when You try to ping to select the correct interface it's happened to forget that Smile
so try ping a.b.c.x -I a.b.c.d

Shoot...it was that easy?

Perhaps someone should review the wiki article I mentioned. It leads the reader to believe that it's far more difficult to pull that off.
