Several *different* subnets? How? To make things clearer, suppose that there is one subnet, partly physical, partly virtual (maybe this is not the right word), as follows: H1 (border firewall) has 2 nics: - 192.168.1.0 <---> (via dynamic IP/pppd) Internet - 192.168.2.20 <---> H2 H2 (services) has 1 nic: - 192.168.2.10 On H2: - vserver (apache): 192.168.2.55 Can I create a second purely virtual net inside H2, say 192.168.3.0 ? [Where I would put e.g. a "mysql" vserver, with address 192.168.3.55.] > but all communication on the same host > will happen via lo (see More Documentation on the > linux-vserver wiki), so you have to keep that in mind. > Is it on http://www.linux-vserver.org/index.php?page=Documentation Which document? > > If I remember correctly, "vmware" does that (as was already > > pointed out by someone else). > > So the question is: How to do it with vserver? > > vmware and QEMU or Bochs use a separate kernel (similar > to that what UML does) and communicate via tun/tap > devices with the host, which adds some overhead but > provides separated 'interfaces' on the host ... > Is it possible to have the same kind of communication between vservers?
