Greetings everyone,
I have been using OpenVZ for a number of months in a hosting environment
but now I wish to bring an internal node online running OpenVZ and would
like your input on my plans.
At first I will be running just the one node with about 5 or 6 VE's on
the node. I have no problems installing OpenVZ and creating VE's but I
am under the impression that a VE can not "see" any other VE's on the
same node, is this correct? I ask because one of the VE's will be
running a DNS serverfor our internal network. of the others one will be
running Apache, one will be running Lighttpd and one will be running
Qmail with the other two undecided as yet.
Is this workable with the DNS server on the same node as the VE's or do
I need to being a second node online to run the DNS from?
Many thanks and have a Very Merry Xmas.

The VEs send all their traffic to the Hostnode. So by default the VEs can
communicate with the HN only. For any other kind of communication you have to
enable IP-Forwarding on HN - usually one does this together with Proxyarp.
By doing this the VEs can communicate quite well because the HN does all the
routing. So there should be no problem with your plans.
For further information fire up a search-engine and ask for "Pseudobridge with
proxyarp". There is a howto somewhere that covers this.
Cheers,
Konstantin
