As of Oracle VM Release 3.4.5, you can disable PVM guests from running on your Oracle VM Server instance. As a result, migrating PVM guests to a destination Oracle VM Server instance with PVM guests disabled is not possible and the following error message is displayed:

stderr: Error: PV guests disabled by xend.

However, when migrating PVM guests with secure vm migration enabled to a destination Oracle VM Server instance with PVM guests disabled, the following incorrect message is displayed:

stderr: Error: [Errno 9] Bad file descriptor 

Workaround: The incorrect migration error message should be ignored. The PVM migration is still prevented regardless of whether secure vm migration is enabled or not for the server pool where the vm resides.

For information on how to disable PVM guests on your Oracle VM Server instance, see Disabling Paravirtualized Guests on Oracle VM Server in the Oracle VM Administrator's Guide. For information on secure VM migrations when creating a server pool, see the Create Server Pool topic in the Oracle VM Manager User's Guide.
