This creates two files. The file myserver.key contains a private key; do not disclose this file to anyone. Carefully protect the private key.
Use the name of the webserver as Common Name (CN). If the domain name (Common Name) is mydomain.com append the domain to the hostname (use the fully qualified domain name).
Your CSR will now have been created. Open the server.csr in a text editor and copy and paste the contents into the email and send to support@hyve.com when requested.
