readlink cause the cpu 100% usage
i have a single node with openstack installed.
about few days ago, when i boot a vm with "nova boot", the vm hangs in Spawning state, well, i restart the nova,but it does not work.
OK,then i want to reboot the host,but i can not restart the host, finally , i found the readlink process cause the cpu 100% usage.
