Oracle Virtualbox Serial Ports
Oracle VM VirtualBox Windows, Mac OS X, Linux Oracle VM VirtualBox is cross-platform virtualization software that allows to extend existing computer to run multiple operating systems at the same time. Designed for IT professionals and developers, Oracle VM VirtualBox runs on, and Oracle Solaris systems and is ideal for. I needed to test serial communication between two VirtualBox guest machines on Linux. This tutorial describes what I did to set up a serial port between two virtual machines running on VirtualBox. My host operating system was Ubuntu 10.10 My guest operating systems were Microsoft Windows XP.
I'm having trouble for a few weeks now trying to access the serial port of my computer when working on the guest OS Windows XP Pro via VirtualBox. The host OS is Ubuntu 10.04 LTS and I'm using VirtualBox 5.0.18. In its settings, I've set up the serial port as on this screenshot:
..but then I can't run the virtual machine:
I've already asked the VirtualBox forum but they replied it was more a Ubuntu problem than a VB one, so I'm asking for help here!
The thing I'm trying to do is to back up an old device (from the early 2000s or late 1990s), which back-up software can only be opened on Windows. I've managed to install and open it on my XP guest OS, but it cannot communicate with the peripheral device.
Excuse me if I'm not always intelligible, I'm not used to run Ubuntu and I'm French, so my English may not be perfect!
Thanks in advance though :)

Your user is not in the group that has access the serial port. You can either run Virtualbox as root (Not recommended ), or add your user to the group.
You might have to logout and login again to make this work.

First check the actual permissions on your host system. Something like:
Oracle Vm Virtualbox Download
~ ls -l /dev/ttyS0
Juegos psp iso. Mine is:
crw-rw---- 1 root dialout 4, 64 2016-05-24 07:34:52 /dev/ttyS0
This means thay either I need to be root (first 'rw-' from left) or I need to be in the dialout group (second 'rw-' from left).Try from command line a check with command id like:
~ iduid=1000(enzo) gid=1000(enzo) groups=1000(enzo),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),113(lpadmin),127(sambashare)
In this case I cannot access that serial port. So I can add myself to dialout group:
~ sudo usermod -a -G dialout enzowhere enzo is your very userid as shown above by command idThen you need to logout and log back in in orderto have this change effective.

So I changed /dev/ttyS0 to /dev/ttyUSB0 and it works like a charm.
