The "not enough hosts" could be due to any number of reasons. To know
exactly why, check your /var/log/nova/nova-scheduler.log on
controller. The error means that nova scheduler was not able to find
any suitable hosts to boot the VM. It could be for example because you
are using a flavor that does not fit, or because your compute node
appears dead to controller. In any case, nova scheduler log should
make it a bit clearer.
