From aa8896990f75d7c5c041f9bf5b198bc947b72518 Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (VMware)" Date: Tue, 7 Feb 2017 12:13:08 -0500 Subject: [PATCH] ktest.pl: Powercycle the box on reboot if no connection can be made When performing a reboot of the test box, try to ssh to it. If it can't connect for 5 seconds, then powercycle the box. This is useful because the reboot is done via ssh, and if you can't ssh to the box because it is hung, the reboot fails to reboot.
