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>
