Kevin,

   Make sure you have these options in your /etc/sysctl.conf :

vfs.aio.max_buf_aio=8192
vfs.aio.max_aio_queue_per_proc=65536
vfs.aio.max_aio_per_proc=8192
vfs.aio.max_aio_queue=65536

   ...otherwise the guest I/O will random hang in VirtualBox. This issue was
mitigated in a late 5.x VirtualBox by patching to not use AIO, but the issue
came back in 6.x when that patch wasn't carried forward.
