ORA-12541: TNS: no listener - oracle

Question

I have a VM in Oracle VM Virtual Box running Windows XP. In this VM, I have install Visual Studio .net 2003 with nhibertante ORM to connect to BBDD Oracle 12.2.
Oracle database is hosts in my physical machine with Windows 11 SO. The network configuration between VM and host that ok, or I suppose it, because the ping network servicio work ok.
In my VM I run a SQL*Plus command interface and I try to connect to Oracle database in the host machine.
I use the follow command: sqlplus user/pass#service
Well, the error I receive is:
ORA-12541: TNS: no listener
Maybe some configuration in listener.ora or tnsname.ora not be ok, but I tried modify several parameter but it didn't work.
My tnsname.ora in VM is:
`LISTENER =
(ADDRESS =
(PROTOCOL = TCP)
(HOST = 192.168.56.7)
(PORT = 1521)
)
orcl =
(DESCRIPTION =
ADDRESS =
our text`(PROTOCOL = TCP)
(HOST = 192.168.56.7)
(PORT = 1521)
)
(CONNECT_DATA =
(SERVER = dedicated)
(SERVICE_NAME = orcl)
)
)
`
My listener.ora in my host machine is:
`SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = orcl)
(ORACLE_HOME = C:\app\orclDiego\product\12.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:C:\app\orclDiego\product\12.2.0\dbhome_1\bin\oraclr12.dll")
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.7)(PORT = 1521))
)
)
