There is a clean up process for a new install of cloudstack especially dropping
cloud database and running database creation script for creating it again, it
is typical for SSVM to show up for few seconds and shutdown (cycle) if your

image the hard drive of SSVM from template and finds nothing or has a problem
downloading it from secondary storage and shuts down. You may have to send us
management server log under /var/log/ to see at what stage it is failing,
