Nope, they can run on computer just like any other operating system like
Windows and Linux. You can use GRUB 2 to boot an RTEMS OS + application
image. But I don't know how they can be debugged in this way.


 If it have to be with qemu, what instructions I should follow?

In order to debug your application when it is running on QEMU, you should
start your QEMU with -s option. This option will launch a GDB server on
localhost:1234. Then use a debugger interface like kDBG or eclipse to
remotely debug your running application. For instance, in kDBG you may
change the debugger in Settings > Global Options menu to i386-rtems4.11-gdb
and then if you start kdbg like:
kdbg -r 127.0.0.1:1234 /ELF/version/of/your/application/path/and/name
you'll be able to debug your application.
Just remember that you must start QEMU before kDBG and introduce the same
ELF file to both of them.

Hope it helps,
