[FreeBSD]GuestOS hung up with HDD IO error on VirtualBox

When Guest OS system on VirtualBox runs with heavy disk I/O (e.g. upgrade package, apt-get install, etc),  Guest OS hung up with kernel I/O error(AHCI error etc...). But there is no I/O error on HostOS.

[SOLUTION]
 enabled Use Host I/O Cache
