Hi, I'm trying to run the xen with the NAT mode.


I referenced the 'http://wiki.kartbuilding.net/index.php/Xen_Networking#Routed_Networking_with_NAT_2'.

I inserted the 'vif = [ "ip=" ] at the end of the dom1.cfg.


When I run the dom1 using the virt-manager, the vncdisplay dosen't show the POST screen.


It just shows the text 'Console is not yet active for guest' and the CPU usage is 0%.

Did you ask the wiki author about the problem?


However the Memory usage shows 512MB which is configured when domain creating.


After deleting the 'vif = [ "ip=" ]' in the dom1.cfg and reruns the dom1, it works very well.


DId I wrong configure the dom1.cfg??

Usually /var/log/xen/xend.log and /var/log/xen/dm-*.log will help determine the problem.


Thanks for reading.


PS) dom0: CentOS 5.5 + xen 3.1

Is this the default packaged Xen?
If yes, and you only need one-way NAT (for domU to access outside network), it'd be easier if you just use bridged networking and virbr0 bridge (which is created by default). Note that when creating domU config file manually, you should specify a static MAC for domU.
