i booted 8 machines: test1: hung after "XENBUS: Device with no driver: device/console/0" test2: hung after "XENBUS: Device with no driver: device/console/0" test3: "Unable to mount root fs" list partitions: "sda1 sdb1" and shut down test4: hung after "XENBUS: Device with no driver: device/console/0" test5: booted completely, SSH works, can write files, ... test6: booted completely, SSH works, can write files, ... test7: "Unable to mount root fs" list partitions: "sda1 sdb1" and shut down test8: hung after "XENBUS: Device with no driver: device/console/0" - all 8 xm's are defunct on the host. - i have about 15 "/var/run/tap/tapctrlwrite35 /var/run/tap/tapctrlread35" processes and 2 "/var/run/tap/tapctrlwrite34 /var/run/tap/tapctrlread34" - all 6 up machines have 2 blktap processes (sda1 and sdb1) is there ANYTHING i can try? does anyone have any idea??? i'm completely stuck here... i've already rebooted the host, to see if it would help.
