Documentation should describe OpenStack use

Docs should describe how to build OpenStack qcow2 images
Building examples, e.g. acorn provide an acorn ELF binary and an acorn image with DOS/MBR.

Presumably a conversion of the form
qemu-img convert -O qcow2 acorn.img acorn.qcow2
is required

Then upload the image as
openstack image create --container-format bare --disk-format qcow2 --file acorn.qcow2 includeos_acorn

The create a server using something like
openstack server create --nic net-id=mynet --flavor tiny --image includeos_acorn includeos_acorn

But as openstack console log show includeos_acorn shows no text, presumably there are other necessary steps.

For info, I did succeed with booting this on OpenStack.

I needed to modify my image (includeos_acorn) as follows:
openstack image set --property hw_disk_bus=ide includeos_acorn

I found this perusing an old issue, it would be nice to document this here.
Once I'd done that I could obtain the console output using
openstack console log show includeos_acorn

I'd also forgotten to specifically create a security group allowing access to port 80 for the acorn web server example.

Once I'd done that I could access the acorn web server.
