Do you have permissions set correctly to access the serial port
normally (without virtualbox)?
How do I check if some other application are not using serial port?
To check to see if another app has the port open, use lsof. But,
that's not what's causing your error. Linux allows serial ports to be
open by multiple processes.

When I run: lsof -n |grep /dev/ttyS
nothing is showing up so I'm sure no other application is using it. I run
hylafax but I disabled it and commented out in inittab:
#c7:2345:respawn:/usr/sbin/faxgetty ttyS0
I set ttyS0 to "666"
ll /dev/ttyS*
crw-rw-rw- 1 uucp tty 4, 64 Sep 18 09:21 /dev/ttyS0
crw-rw---- 1 root uucp 4, 65 Sep 2 06:09 /dev/ttyS1
crw-rw---- 1 root uucp 4, 66 Sep 2 06:09 /dev/ttyS2
crw-rw---- 1 root uucp 4, 67 Sep 2 06:09 /dev/ttyS3
I'm in group "tty", so I can not figure it out why virtualbox is complaining.
