Hello Peter If you dig into logs a little bit more, you can see the actual reason for the error. The usual errors are insufficient server capacity exception like not enough cpu, memory, ip address or mismatch between template tag and host tag or some other mismatch in the tags. These are the common errors I have seen. Search for "startVirtualMachine" api and trace its jobid which is usually like "context-<some number>" and look at the logs
