I have downloaded Sage 6.3 for Windows and it is provided in OVA format. It is said in manual, that to run Sage, one should:
First, start VirtualBox. To start the Sage notebook server, power on Sage-x.y.z by selecting it and clicking 'Start'. (This may take awhile. You may see some warning messages you can safely ignore.)
I don't understand, what does "power on" verb mean.
If I double click this file in File Explorer, it starting an operation, called "import":
Looks like it goes to create new virtual machine from the given OVA file.
Can I just RUN this OVA file without creating any entries anywhere and importing something to somewhere? Was it intended to be so?
Or the only operation available for OVA file is "importing"?
