Interaction between Virtual
Machines of Other Vendors and
Parallels Network Adapter
Machines of Other Vendors and
Parallels Network Adapter
If in addition to Parallels Workstation you have installed on your computer virtual machine
software developed by vendors other than Parallels Software International Inc., a problem with
a network adapter for an external virtual machine is possible. Alternative virtual software may
assume Parallels virtual network adapter, Parallels Host-Guest Virtual NIC, to be a real network
interface and connect an external virtual machine network adapter to it. This problem is
especially probable if the external virtual machine chooses network adapter automatically.

If the problem described above occurs, you will receive an error when trying to access Internet
in an external virtual machine. To solve the problem:
in an external virtual machine. To solve the problem:
Open this virtual machine configuration and select a physical network adapter.
The Parallels Workstation adds Parallels Host-Guest Virtual NIC network adapter to the list of
network adapters in primary operating system during the installation process. This adapter is
required for host-only network (page 132).

Problem with Printing
If you have a physical printer connected to an LPT port of your computer but you can not print
from primary operating system and/or several virtual machines despite the printer being
properly connected and configured, this may be caused by the following reason: the running
virtual machine's parallel port is connected to a real LPT port which is blocking this LPT port. If
printer cable is attached to that port of a physical computer, no other virtual machine as well as
primary operating system can access printer.

To solve the problem:
find a virtual machine from where you can print,
disconnect its parallel port which is connected to the real LPT port. See Connecting
disconnect its parallel port which is connected to the real LPT port. See Connecting
Serial/Parallel Port (page 159).
Documents that have been sent for printing in primary OS or other virtual machines while you
were unable to print are accumulated in the spooler and will be printed according to the
sequence they arrived. If you run several virtual machines with their parallel ports connected to
printer through the same physical LPT port, you may be required to consequently disconnect
their parallel ports to print all the documents.
