macOS works on BitVisor on Intel Mac.  Turning off Secure Boot using
Startup Security Utility on recovery environment is needed before
starting BitVisor.  Enabling DMAR pass-through might be needed to use
some devices on macOS.

SQLite code can be used in processes in process/sqlite/ directory.
Example implementation is process/sqlite/sqliteexample.c which can be
launched from dbgsh.  The database can be stored to volatile memory or
non-volatile storage (a hard disk drive or a solid state drive
connected to ATA/AHCI or NVMe).  However currently no file system is
supported.  The database will be stored to raw sectors.  In addition,
the storage access only works while the ATA/AHCI/NVMe controllers are
in active state (i.e. the guest operating system driver needs to be
working).
