Oracle XE: Transfer Database from Linux to Windows
You should be able to solve this with a full export and import of the database. 


Run a full export of the database on the linux VM
Copy the dump file to your Windows machine
Do a full import to the database on the Windows machine. 


I believe Oracle reccomends the use of Oracle Data Pump:  expdp and impdp on Oracle 11g and up, rather than the traditional imp and exp tools. 

Oracle Data Pump is well documented: http://docs.oracle.com/cd/E11882_01/server.112/e16536/part_dp.htm
