Hypervisor disk images

If you make changes to the hypervisor host or the guests, you need to create a new bootable disk image with the hypervisor system and transfer it to your target.

Disk image partitions

If your BSP came with QNX Hypervisor, the hypervisor disk image includes the hypervisor host in a bootable partition and the guests in a data partition:

bootable partition
Type 11 (DOS). Includes at least one bootable IFS (usually several) for the hypervisor host.
You can use this partition to copy files to this disk from any development host that can access a DOS filesystem. This is useful if you ever need to transfer files from your development host to your target.
data partition
Type 177 (QNX PowerSafe). Includes an IFS for each guest in the reference image, and at least one qvm configuration file for each VM for these guests.

For other BSPs, you can create a similar partition configuration. For information about building a disk image with multiple partitions, refer to the Building an OS image section in the Building Embedded Systems guide, or the diskimage entry in the QNX OS Utilities Reference.

Changing partition sizes

If you need to change the sizes of your partitions, before you build the hypervisor system, you can adjust the disk configuration in the disk.cfg and the part_*.build files in the images/ directory of the board-specific BSP for your target platform.
