SSH ping etc not working between dom0 and domU''s
Hi! I have a problem with my new Xen setup. I have installed Debian etch with netinstall and I''m using 2.6.18-6-xen-amd64 kernel in my dom0 and 3.0.3-0-4 version xen hypervisor. I''m using four network cards on my system and using three of them as xen bridges and dom0 is using the fourth one only for it''s own. So basicly both of my virtual servers use a network card

Xen Networking Issue with CentOS 5.1
Hi, I tried this post on the Xen list first with no answer. I have 4 machines and 3 of which (all different) have no network access when booted into Xen. I tried using Fedora Core 8 and it produced the same results. Is it normal for the virbr0 interface to take an arbitrary IP? How does it decide what to use? An ifconfig when booted into Xen shows the following: eth0 Link encap:Ethernet

Got that figured out no problem, now i want to have a second bridge that runs a local network for all the doms that doesn''t connect to the network. With code I have found used in multiple places I can easily get 2 bridges, and
