i tried the command "echo 0 > /sys/devices/system/cpu/cpu1/online",
but after that the console was halt, and sometimes system was halt.
no message left in "xm dmesg" "dmesg" "/var/log/xen/xen-hotplug.log"
xen version i used is 4.0.1-rc2, the domU kernel is xenified linux-2.6.31.8
and also i did an experiment without xen on linux-2.6.31.8(the config is just without xen options), the command above can work
how can i unplug a physical cpu on xen? is that not supported by xen yet?
i'm a newer to this field, maybe just a simple question, please help
