[ovirt-users] Host remains Non-Responsive after reboot

[Rob Abshear]

I have done a bit more investigating on this matter.  If I restart the node
from within oVirt using the power management option "restart", then the
node restarts and vdsmd DOES NOT start.  If I go into the DRAC and issue
the command to power cycle the machine, then the machine restarts and vdsmd
DOES start.  I can run the following command from another node in the
cluster:
fence_drac5 -a 192.168.200.105 -l root -p <password> -x -o reboot
and the node restarts and vdsmd DOES start.
