Cannot reboot instance (after host powered off unexpectedly)
My compute.log looks like this after this happened:

Need help to recover from this...
You seem to have more than 1 VM on the host, are all VM's down or is a single VM not able to reboot?
Jobin, other 5 VMs are able to boot, only 1 had this problem.
