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. -DG _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
