I struggled to figure out why a machine create was failing, and eventually asked if anyone else had seen the vague error I was getting: "Error creating machine: Process exited with: 100. Reason was: ()" It is immensely helpful if we log the command output instead of just the rc. It would also have been useful if the driver providers used the output, but this covers most scenarios since they don't. Signed-off-by: Christy Perez <christy@linux.vnet.ibm.com>
