HVM bug: system crashes after offline online a vcpu
Hi Konrad
I encountered a bug when trying to bring offline a cpu then online it
again in HVM. As I''m not very familiar with HVM stuffs I cannot come up
with a quick fix.
The HVM DomU is configured with 4 vcpus. After booting into command
prompt, I do following operations.
# echo 0 > /sys/devices/system/cpu/cpu3/online
# echo 1 > /sys/devices/system/cpu/cpu3/online
