Some users consider disk image files inconvenient because they cannot be inspected and manipulated with regular shell utilities. Especially scenarios where many VMs are launched with VM-specific data files can benefit from using files directly instead of building disk images. I'm not saying all users just export per-VM directories, but it's a common case and may be a good starting point if a general solution is very hard. --v9Ux+11Zm5mwPlX6 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEcBAEBAgAGBQJZHF8qAAoJEJykq7OBq3PIRQMIAJO48x1xCDK2w+5TNOsSL8j4 PKDY2WKzo7NZ0voHI9Hfcr0n980KAZxBk4DU6yHLk8+DYS2O9ipQ88vlBTd1f1lS 0SWVcJ8zCuFvKPvcGjscUEb9OcRBszZXj2OFeq8nt6F4/KPvYeWybGhUNVV2llMU 1eKLvUmsuvKAStF5hRt7835pgjV4LQRQwwZAG0NKn5+h0Z2FavCkDUwcf6shueE8 aY+7zljETyzfGqiX79mHvxYB+TW1RUS6Eus+mLPLvZbRYq4/hPlg1bFxs7//bUiP i5LMGbB3x3FW8vPpddaa+qVb9P16Sm1Ns6aUvLcpGqptD+jiyl898Uq17NRcZI8= =H5vy -----END PGP SIGNATURE----- --v9Ux+11Zm5mwPlX6--
