Hi Xen-Folks, I googled around the web and browsed the list archives, but I couldn''t get a clear answer to my question. Is it possible to have dom0 and domU working in two seperate subnets and how is this configured? I have now a default dom0 with one network interface and bridging enabled. When the domU, which schould get an ip-address from a seperate subnet, tries to acquire a dhcp-lease it doesn''t get any reply from the dhcp server. It would be nice if someone could confirm, that he has got dom0 and domu in seperate subnets working and the problems I have probably belongs to the dhcp server. Thanks for your help, Jan _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
It should be possible, but the hardware will need to be attached to both subnets in some way. The simplest way to do that would probably be with two interfaces, one on each subnet. Dom0 would have an IP address on one interface but not the other. The other interface would be set up to bridge to that other subnet for domU. This could probably also be done with vlans and one interface. -Dylan> Hi Xen-Folks, > > I googled around the web and browsed the list archives, but I > couldn''t get a clear answer to my question. > > Is it possible to have dom0 and domU working in two seperate subnets > and how is this configured? > > I have now a default dom0 with one network interface and bridging > enabled.

Hi Dylan, thanks for your short explanation! Have you tested a setup with one interface and vlans? I must admit that I''m not that deep in the network stuff to understand what to do. I need to read into it. Do you have any ressources where I can read about setting up such a layout with one interface?

(sorry for top posting, just following suit) I have a dom0 cluster running clustered VMs that exist on VLANs that dom0 is not on. My architecture sounds a bit more complicated than what you want, but you might be able to dig the basics out of my how-to posted at www.certifried.com Mark Jan Michael wrote:> Hi Dylan, > > thanks for your short explanation!

I have a Xen system with 3 different subnets (via vlans), and dom0 doesn''t have an IP address on one of them (just bridged) So it''s possible.
