ORA-12505 + "network adapter could not establish the connection" on Oracle11g/VirtualBox - oracle11g

Question

I have Oracle 11g installed locally on each of my virtualbox machines (working under Windows 7 64bit). Suddenty, after a simple reboot, the database on one of the 5 virtual machines doesn't want to connect anymore.
With SID connection I obtain ORA-12505 error, and with service name : "Network adapter could not establish the connection", in SqlDeveloper with both cases. If I try a connection with SqlPlus as sysdba, I obtain the connection but with "connected to an idle instance". Hence if I try to see, for example, the list of sessions and processes working, I have the error 01034 ("ORACLE not available"). I tried a lot of tricks but nothing works. Could it be a specific problem with virtual machines ?
Here what I tried :
the services (of my base and of the listener) are working (and I wait enough between relaunch and connection retry) ;
the files tnsnames.ora, listener.ora and sqlnet.ora seem correct (see below) ;
If I force localhost to be 127.0.0.1 in hosts file, I have the 12514 error ;
ORACLE_HOME and ORACLE_SID are correctly set ;
It can't a priori be a memory problem (I even try to allow more memory to the specific VM which doesn't work) ;
If I force "startup" on sysdba session, the next requests obtain : ORA-03114 : not connected to ORACLE ;
It's not a priori a problem of system files size. In all cases, the not working database is not my biggest database among all my databases (and any file in oradata are bigger than in others VMs which have exactly the same configurations).

Answer 1

Did you check the alert log of the database? that could be a good place to start looking.
Also when logged as sysdba, did you try to start the database: startup ?
If yes, what is the error message if any?
