Oracle

I'm really green, so please bear with me :) me and my friend are working on educational project, which is working in oracle. We started to use physical machine for it and when we finished, I decided to transfer everything to virtual machine, but database does not work anymore. Physical server is is still working, but I need to free it up for other project.

There are two DBs, projectdb and prpdb1. I can login to projectdb, but I cannot login to another one, where all the data is located.

P.S.
My friend did all the DB heavy-lifting, but now he is unavailable :( anyway I want to figure it out myself if possible.

What I have tried:

I tried to dig a little bit and found that listener is missing some services (?).

This is log from working system:
