Hello everybody!

Do you know how to pass physical LPT port to the DomU?

I found some information about ioports=[''] but it seems it works only if the port range is the same on the host and VM. My motheboard hasn't any LPT so I use PCI board. Using such board lead to different IO range.

05:01.0 Communication controller: NetMos Technology PCI 9855 Multi-I/O Controller (rev 01)
    Subsystem: LSI Logic / Symbios Logic Device 0014
    Flags: medium devsel, IRQ 22
    I/O ports at ec00 [size=8]
    I/O ports at e880 [size=8]
    I/O ports at e800 [size=8]
    I/O ports at e480 [size=8]
    I/O ports at e400 [size=8]
    I/O ports at e080 [size=16]

Does anybody know how to tell Xen using e080 host io for the 03bc vm io
