Description dtrich0 2014-12-15 09:09:48 UTC 
Created attachment 968829 [details]
/var/log/libvirt/qemu/BMS_AIR.log (the log of the VM)

Description of problem:
When I try to add parallel port to VM I'm getting the error:
"qemu-kvm: -device isa-parallel,chardev=charparallel0,id=parallel0: 'isa-parallel' is not a valid device model name"
and the VM does not start.
Version-Release number of selected component (if applicable):
libvirtd --version
libvirtd (libvirt) 1.1.1

How reproducible:
adding /dev/parport0 as parallel port to the guest OS.

Steps to Reproduce:
1.Show Virtual Hardware Details
2.Add Hardware
3.Parallel
4.Physical host character device (dev)
5.Path:/dev/parport0
6.start VM

Actual results:
Error starting domain: internal error: early end of file from monitor: possible problem:
qemu-kvm: -device isa-parallel,chardev=charparallel0,id=parallel0: 'isa-parallel' is not a valid device model name

libvirtError: internal error: early end of file from monitor: possible problem:
qemu-kvm: -device isa-parallel,chardev=charparallel0,id=parallel0: 'isa-parallel' is not a valid device model name





Expected results:
adding lpt1 to winxp VM.

Comment 1 Cole Robinson 2014-12-15 15:53:04 UTC 
The default qemu-kvm on centos 7 has parallel device support compiled out. Some info here:
