Description Sahid Ferdjaoui 2016-05-30 11:28:02 UTC

After I executed "nova reboot --hard <vm>", I could not access to the vm's serial-console.

The problem is able to be recovered by re-executing "nova reboot --hard <vm>".
And evey time I execute the command, the accessiblity to serial console is changed alternately.

 1. Get Serial Console             => I can access it.
 2. After 1st "nova reboot --hard" => I cannot access it.
 3. After 2nd "nova reboot --hard" => I can access it.
 4. After 3rd "nova reboot --hard" => I cannot access it.
