Hello Team,
I have an openstack environment with 4 compute Nodes however yesterday out of the blue, the Instances on one of the compute nodes started shutting themselves down.
Then I realized the the compute service was disabled when I checked in Horizon. I enabled it and restarted the instances and all was well but I cant figure out what caused it.
I have attached the nova_compute logs here incase someone would like to support

Regards

Tony Karera
