Symptoms

Removing or adding a physical or virtual disk using Oracle Virtual Machine Manager results in failure. 

If a disk is added, it makes it to the host vm server's vm.cfg file for the vm, but the device file (for example, /dev/xvdu) does not get created on the host. rescan-scsi-bus.sh on the vm doesn't help. If the vm is rebooted, the disk device file will show up.

If a disk is deleted, the job fails with below error in the OVM Manager.
