Hi, I installed openstack on ubuntu 11.10 according to doc. But when i run image after uploading ubuntu 8.04.4 image, linux os crashed. The last message on screen is ' rcu_sched_state detected stall on CPU 0' After the crash, i reboot. It is ok at first. But when i start nova-shcedule, the os crash again. Does any one come across this issue? Thanks -------------- next part -------------- An HTML attachment was scrubbed...
