Hi all, I setup Xen3 for the first time using debian etch packages as described at http://www.debian-administration.org/articles/396 . That is I used the Debian xen-create-image to set up a Xen image. This all went fine, without errors (I can also mount and chroot into the image without problems). But when I run # xm create gerd.cfg -c Using config file "/etc/xen/gerd.cfg". Error: Device 0 (vif) could not be connected. Backend device not found. I do not know what causes this. After some fiddling and searching it seems to me like a problem in /etc/xen/scripts/vif-bridge But I miss the knowhow to tell what exactly goes wrong. Here is the from daemon.log when I run "xm create gerd.cfg -c" : /etc/xen/scripts/block: add XENBUS_PATH=backend/vbd/4/2049 /etc/xen/scripts/block: add XENBUS_PATH=backend/vbd/4/2050 /etc/xen/scripts/vif-bridge: online XENBUS_PATH=backend/vif/4/0 /etc/xen/scripts/vif-bridge: Writing backend/vif/4/0/hotplug-status error to xenstore. /etc/xen/scripts/vif-bridge: Could not find bridge, and none was specified /etc/xen/scripts/vif-bridge: offline XENBUS_PATH=backend/vif/4/0 /etc/xen/scripts/vif-bridge: Writing backend/vif/4/0/hotplug-status error to xenstore. /etc/xen/scripts/vif-bridge: Could not find bridge, and none was specified /etc/xen/scripts/xen-hotplug-cleanup: XENBUS_PATH=backend/vif/4/0 /etc/xen/scripts/block: Writing backend/vbd/4/2049/node /dev/loop1 to xenstore. /etc/xen/scripts/block: Writing backend/vbd/4/2049/physical-device 7:1 to xenstore. /etc/xen/scripts/block: Writing backend/vbd/4/2049/hotplug-status connected to xenstore. /etc/xen/scripts/block: remove XENBUS_PATH=backend/vbd/4/2049 /etc/xen/scripts/xen-hotplug-cleanup: XENBUS_PATH=backend/vbd/4/2049 /etc/xen/scripts/block: Writing backend/vbd/4/2050/node /dev/loop1 to xenstore. /etc/xen/scripts/block: Writing backend/vbd/4/2050/physical-device 7:1 to xenstore. /etc/xen/scripts/block: Writing backend/vbd/4/2050/hotplug-status connected to xenstore. /etc/xen/scripts/block: remove XENBUS_PATH=backend/vbd/4/2050 /etc/xen/scripts/xen-hotplug-cleanup: XENBUS_PATH=backend/vbd/4/2050 Here is what xend.log says when I run "xm create gerd.cfg -c" : [2006-06-18 20:25:39 xend.XendDomainInfo] DEBUG (XendDomainInfo:178) XendDomainInfo.create(['vm', ['name', 'gerd'], ['memory', 196], ['vcpus', 1], ['image', ['linux', ['kernel', '/boot/vmlinuz-2.6.16-2-xen-686'], ['ramdisk', '/boot/initrd.img-2.6.16-2-xen-686'], ['root', '/dev/sda1 ro']]], ['device', ['vbd', ['uname', 'file:/home/xen/domains/gerd/disk.img'], ['dev', 'sda1'], ['mode', 'w']]], ['device', ['vbd', ['uname', 'file:/home/xen/domains/gerd/swap.img'], ['dev', 'sda2'], ['mode', 'w']]], ['device', ['vif', ['ip', '192.168.10.70']]]]) [2006-06-18 20:25:39 xend.XendDomainInfo] DEBUG (XendDomainInfo:284) parseConfig: config is ['vm', ['name', 'gerd'], ['memory', 196], ['vcpus', 1], ['image', ['linux', ['kernel', '/boot/vmlinuz-2.6.16-2-xen-686'], ['ramdisk', '/boot/initrd.img-2.6.16-2-xen-686'], ['root', '/dev/sda1 ro']]], ['device', ['vbd', ['uname', 'file:/home/xen/domains/gerd/disk.img'], ['dev', 'sda1'], ['mode', 'w']]], ['device', ['vbd', ['uname', 'file:/home/xen/domains/gerd/swap.img'], ['dev', 'sda2'], ['mode', 'w']]], ['device', ['vif', ['ip', '192.168.10.70']]]] [2006-06-18 20:25:39 xend.XendDomainInfo] DEBUG (XendDomainInfo:380) parseConfig: result is {'ssidref': None, 'uuid': None, 'on_crash': None, 'on_reboot': None, 'image': ['linux', ['kernel', '/boot/vmlinuz-2.6.16-2-xen-686'], ['ramdisk', '/boot/initrd.img-2.6.16-2-xen-686'], ['root', '/dev/sda1 ro']], 'on_poweroff': None, 'cpus': None, 'name': 'gerd', 'backend': [], 'vcpus': 1, 'cpu_weight': None, 'vcpu_avail': None, 'memory': 196, 'device': [('vbd', ['vbd', ['uname', 'file:/home/xen/domains/gerd/disk.img'], ['dev', 'sda1'], ['mode', 'w']]), ('vbd', ['vbd', ['uname', 'file:/home/xen/domains/gerd/swap.img'], ['dev', 'sda2'], ['mode', 'w']]), ('vif', ['vif', ['ip', '192.168.10.70']])], 'bootloader': None, 'cpu': None, 'maxmem': None} [2006-06-18 20:25:39 xend.XendDomainInfo] DEBUG (XendDomainInfo:1164) XendDomainInfo.construct: None 0 [2006-06-18 20:25:39 xend.XendDomainInfo] DEBUG (XendDomainInfo:1196) XendDomainInfo.initDomain: 5 1.0 [2006-06-18 20:25:39 xend] DEBUG (balloon:126) Balloon: free 197; need 197; done.
