which is located in the directory in which you

Click "Run" to launch QEMU.

<note>

717

The host on which you are running QEMU must have

718

the <filename>rpcbind</filename> utility running to be

719

able to make RPC calls on a server on that machine.

720

If QEMU does not invoke and you receive error messages

721

involving <filename>rpcbind</filename>, follow the

722

suggestions to get the service running.

723

As an example, on a new Ubuntu 16.04 LTS installation,

724

you must do the following in order to get QEMU to

725

launch:

726

727

$ sudo apt-get install rpcbind

728

</literallayout>

729

After installing <filename>rpcbind</filename>, you

730

need to edit the

731

<filename>/etc/init.d/rpcbind</filename> file to

732

include the following line:

OPTIONS="-i -w"

</literallayout>

After modifying the file, you need to start the

737

service:

738

739

$ sudo service portmap restart

</literallayout>

<listitem><para>If needed, enter your host root password in

One useful task at this point would be to determine the

<filename>ifconfig</filename> command.

755

The IP address of the QEMU machine appears in the

756

You can use this address to help you see which particular

<title>Deploying and Debugging the Application</title>

766

767

<para>

768

Once the QEMU emulator is running the image, you can deploy

769

your application using the Eclipse IDE and then use

770

the emulator to perform debugging.

771

Follow these steps to deploy the application.

772

<note>

773

Currently, Eclipse does not support SSH port forwarding.

774

Consequently, if you need to run or debug a remote

775

application using the host display, you must create a

776

tunneling connection from outside Eclipse and keep

777

that connection alive during your work.

778

For example, in a new terminal, run the following:

779

780

$ ssh -XY <replaceable>user_name</replaceable>@<replaceable>remote_host_ip</replaceable>

781

</literallayout>

782

Using the above form, here is an example:

783

784

$ ssh -XY root@192.168.7.2

785

</literallayout>

786

After running the command, add the command to be executed

787

in Eclipse's run configuration before the application

as follows:

export DISPLAY=:10.0

</literallayout>

Be sure to not destroy the connection during your QEMU

793

session (i.e. do not

794

exit out of or close that shell).
