Booting the host

You can boot and run the hypervisor without booting any guests. After the hypervisor has booted, you will be able to have a look at its activity (see “Viewing hypervisor activity”), then boot the guests (see “Starting and using guests”).

Intel Supermicro Denverton

For more information about booting the Intel Atom Denverton, see the board manufacturer's documentation.

In its default configuration, the Denverton boots from a BIOS (rather than a UEFI). QNX hypervisors expect that the board will have booted from its BIOS.

To boot the hypervisor on the Denverton:

1. If you haven't done so already, connect a terminal on your host system to the Denverton's serial port, and start your terminal program.
2. With the board power supply disconnected, insert the USB key with the bootable image into the USB slot closest to the top of the board.
3. Connect the board power supply. We recommend that you use a power bar.
4. Press the board's ON/OFF button to power it on.

The hypervisor should boot on the board, and you should soon see something like the following on the board display:

Troubleshooting

Note the following about booting on an Intel Supermicro Denverton board:

• To have your hard drive detected, when you start the devb-ahci driver set the number of ports to 6 or greater; for example:

  devb-ahci ahci numports=6

  On some Denverton boards, you may also need to specify an index for the SATA port; for example, for SATA port 1:

  devb-ahci ahci index=1 numports=6

• The 10 Gigabit ethernet controller doesn't work on 10/100 switches; it never detects the link. Use a Gigabit connection instead to have the link come up.
• If the hypervisor doesn't boot from the USB key on your target, and instead the boot menu appears on the board's display, try reformatting the USB key's partition table to GPT format, and booting again.

R-Car H3

The Renesas R-Car H3 Salvator-X has two SD card readers. You can use either one to transfer your hypervisor system image to your target. The R-Car H3 Starter Kit has only one (micro) SD card reader.

To get a hypervisor system image onto your Renesas R-Car H3 target:

1. On your development host system, transfer the QHS or other QNX hypervisor bootable disk image to an SD card (see “Transferring the disk image” in the “Building a QNX Hypervisor System” chapter).
2. Eject the SD card from your host system and insert it into an SD slot on your board.
3. Confirm that your target's DIP switches are set to put your board in 64-bit mode, and to boot in HyperFlash mode (see the QNX BSP User's Guide for your board).
4. If you haven't done so already, connect a terminal on your host system to your board's serial port, and start your terminal program.
5. Reset the target board or cycle the power to reboot the board. After the QHS or other QNX hypervisor IPL loads, press M to boot from the SD card.

The QNX hypervisor should boot on the board, and the serial console on your host should display output from the hypervisor boot process.

When the hypervisor has finished booting, you should see on your serial console a message confirming a successful boot.
