Title:
Nova resize returns error code 255
Status in OpenStack Compute (Nova):
Invalid
Bug description:
When running "nova resize" command on an active VM, it completed
without any error. However the VM went into error state. The scheduler
somehow dispatched the job to an incorrect hypervisor (i.e.
10.52.224.45 instead of actual hosting hypervisor wpc0043 which is
10.52.225.43) and returned error code 255.
