Re: Is it possible to boot Ubuntu-RT as pre-launched vm

Liu, Fuzhong


The pre-condition to access pre-launched vm: there is serial port on your board.


The function should be ok for RTVM using ubuntu rootfs; but RT performance may be impacted by some services of ubuntu OS.

You can refer following xml:


        <pci_dev>00:17.0 SATA controller: Intel Corporation Device 9dd3 (rev 30)</pci_dev>

        <pci_dev>03:00.0 Ethernet controller: Intel Corporation I210 Gigabit Network Connection (rev 03)</pci_dev>



Please update the bdf info to match your setup.

          I would like to use ubuntu with a kernel patched with RT as pre launched vm in a hybrid scenario. Is this case applicable? If so, is there any reference link for that?
