From: Masayoshi Mizuma <[email protected]> Unexpected power cycle occurs while the installation of the kernel.
ssh root@Test sync ... [0 seconds] SUCCESS ssh root@Test reboot ... [1 second] FAILED! virsh destroy Test; sleep 5; virsh start Test ... [6 seconds] SUCCESS That is because REBOOT, the default is "ssh $SSH_USER@$MACHINE reboot", exits as 255 even if the reboot is successfully done, like as: ]# ssh root@Test reboot Connection to Test closed by remote host. ]# echo $? 255 ]# To avoid the unexpected power cycle, introduce a new parameter, REBOOT_RETURN_CODE to judge whether REBOOT is successfully done or not.
