I'm trying to move from Fedora Core 5 to Fedora 7. I've run into an issue where the xen guests, which need several bridged interfaces bound to dummy devices so they can communicate with each other (similar to host-only networking with VMWare), won't boot. I think I've traced the problem to a lack of the dummy1, dummy2, and dummy3 devices, and I'm not sure how to fix it. What I'll describe below is the setup that worked in Fedora Core 5: I used the following custom network-bridge script: #!/bin/sh dir=$(dirname "$0") "$dir/network-bridge" "$@" vifnum=0 netdev=dummy0 "$dir/network-bridge" "$@" vifnum=1 netdev=dummy1 "$dir/network-bridge" "$@" vifnum=2 netdev=dummy2 "$dir/network-bridge" "$@" vifnum=3 netdev=dummy3 And the following line was used in the .xen files passed to xm create: vif = ['mac=2E:22:22:22:22:20,bridge=xenbr1', 'mac=2E:22:22:22:22:21,bridge=xenbr2', 'mac=2E:22:22:22:22:22,bridge=xenbr3'] Running the script resulted in the following: Using config file "./guest1.xen". Error: Device 0 (vif) could not be connected. Could not find bridge device xenbr1 If I try to run the custom network-bridge script manually passing the "start" command I get several errors: Device "dummy1" does not exist. usage: ifdown <device name> Device "dummy1" does not exist. Cannot find device "dummy1" SIOCGIFFLAGS: No such device Device "dummy2" does not exist. usage: ifdown <device name> Device "dummy2" does not exist. Cannot find device "dummy2" SIOCGIFFLAGS: No such device Device "dummy3" does not exist. usage: ifdown <device name> Device "dummy3" does not exist. Cannot find device "dummy3" SIOCGIFFLAGS: No such device Any ideas on how to get this working would be greatly appreciated. - David -- Fedora-xen mailing list Fedora-xen@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-xen
