[Xen-users] Re: How should I configure my virtual network?
I found this page: http://watzmann.net/blog/index.php/2007/04/27/networking_with_kvm_and_libvirt and decided to use to for my network setup. I tried lots of configurations in libvirt's virtual networking, but nothing worked. I think for my purposes -- using a physical DHCP server -- doing an actual bridge through network-scripts and setting the domains to use that bridge is more practical.

Hi,
I've got Xen mostly setup, but I'm trying to connect to a guest OS from another system on my network. I've been reading over libvirt information to figure out my network xml configuration options (http://libvirt.org/formatnetwork.html). Right now, I'm using a fairly default network w/ forward mode='nat', standard bridge, ip address='192.168.122.1' netmask='255.255.255.0' and dhcp range start='192.168.122.2' end='192.168.122.254'.
My network has different IPs than that, so i'll just say for example, my computers within the network are at ips 123.45.68.*. My physical network device has been assigned an IP in this range by the DHCP server. My bridge reads as having the ip I listed for it above, and any guest OS has an IP within that 192.168.122.2->254 range and they always have internet connectivity. So outbound isn't a problem, but I'm having trouble connecting to guest OSs from other computers in my network. Ideally, I would like all guest OSs to fall in that same 123.45.68.* category and have their IPs automatically assigned by the actual DHCP server.
I think I shouldn't use NATing, but what other configurations should I apply? Specifically, I don't know what to do with the <ip> block, because it wants me to specify the bridge's ip address and then a dhcp range, but I don't want it to hand out a specific IP itself, I want the router's DHCP server to do that. Thanks in advance for replies.
Regards,
Kris
