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.
