Suppose I launch a VM with m1.tiny flavour which has 1GB of storage and 512MB of RAM. Assume I ssh into my VM from its physical host machine and using scp command I copy a file from the physical host to the VM where the file size is more than 1GB or if I simply download a file in the VM's browser which is of more than 1GB. What happens then? Does Nova take care of scaling up the required resources or is there an error? And also if Nova does scale up the resources what will be the new flavor of the VM?
