Virtualization Implemented by Parallel
Port Pass Through
By the utilization of the parallel port pass through, the Parallel Text-based LCM implements the
following three kinds of virtualization in the Guest OS.
- QEMU/KVM
- Xen
- VMWare Player
Here, we take the Fedora 20 x86_64 operation system for instance to explain 3 virtualization
respectively for parallel port pass through. Use the procedures listed below for step-by-step
instructions separately based on your case.
In case of QEMU/KVM or Xen, please use the following steps as a guideline to implement the
virtualization :
(1) Make sure that the Guest OS has been installed.
(2) Add the following 4 lines into the xml file
(for example, add to /etc/libvirt/qemu/<yourvirtualmachine>.xml in linux KVM):
<parallel type='dev'>
<source path='/dev/parport0'/>
<target port='0'/>
</parallel>
(3) Open a terminal in the Guest OS and then issue the following commands to install Linux
Kernel drivers.
# modprobe parport
# modprobe parport_pc
# modprobe ppdev
(4) Check that whether the /dev/parport0 exists or not. You may not find proper /dev/parport0
in the device list, please reconfirm the setup of xml file in the Guest OS.
(5) Reboot the Guest OS.
