Hello, Here is my problem with Xen : every thing works just fine until I need to shutdown or reboot the dom0, but then xenstored fails to stop. The init process continues without problem until : Halting system... xenbus_dev_shutdown: backend/console/5/0: Initialising != Connected, skipping At this point, the system hangs, it doesn''t reboot or poweroff. Strange thing : if, instead of switching to runlevel 0 or runlevel 6, I do "by hand" all the processes in these runlevels (that is : /etc/init.d/xenconsoled stop /etc/init.d/xendomains stop /etc/init.d/smartd stop and so on ...) then the machine switch off or reboot nicely (still with a warning from xenstored, which fails to stop). I have not been able to fix this problem, or even to find its cause. Can anyone point me to the right direction ? The system is : CentOS-6.2 xen-4.1.2-2.el6.x86_64 * kernel-2.6.32-131.21.1.el6.xendom0.x86_64 * kernel-2.6.32-220.7.1.el6.x86_64 * from http://xenbits.xen.org/people/mayoung/ Thanks, -- Philippe Naudin
