For me it wasn't =) ! For my knowledge, HVM extension was needed by xen only for fully-virtualized OS. (like Microsoft OS and other closed source OS ; because no modification can't be made to their kernel to make them aware of "xen".). But maybe i'm wrong ! And if you're right, it will explain why networking don't work (and will never on my system) --> but keep in mind that xen exist a "long time" before hvm extension do. And I thought that other people made networking works in their xen VM. So, I tought that i can get rid of this problem without hvm set on. Someone can light me more about it ? thanks -- Guillaume -- Fedora-xen mailing list Fedora-xen@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-xen
