Re: Autostarting VMs on KVM?
In short – no that is not a use case CloudStack is designed for, the VM states are controlled by CloudStack management. You should however look at using HA service offerings and host HA (if you meet all the pre-requisites). Between these mechanisms VMs can be brought up on other hosts if a host goes down.
Alternatively if you are looking to trigger an automated startup of VMs I suggest you simply script this with e.g. cloudmonkey. Keep in mind this still requires a healthy management server though.

On boot of the server, I would like the VMs to start up automatically, rather than me having to go to the management console and start them manually. We suffered some downtime and in restarting the hardware, I had to manually get everything back up and running.
