[Fedora-xen] running xen without libvirt, etc

Hi all, Very confused as to which list I should post: xen, fedora, fedora-xen. Apologies if this is the wrong one. Pointer to the most appropriate list is welcome. Current system is f14 with full updates, myoung's kernel 2.6.32.+, booted with xen 4.0.1. Hardware is AMD with svm, lotsa ram. After fighting with the all-in-one GUIs for virtmanager I gave up and tried to recycle my configs from a 2006 box running xen3 (which still purrs) and can't even get past scripts/network-bridge without a hang or no bridges. I'm not asking for help on creating a vm, just on getting dom0 to recognize even one single bridge, even the default one. My feeling is that if I can get that far I can take it from here. Does anybody have a working example of a current xend-config.sxp for a machine running xend with f14? Thanx, Mike Wright
