Hey guys,

The instance can not boot from local disk after installing system with ISO. It says, 'No bootable device'. Sorry,I can not upload the screen shot.

1st, I created new flavor in order to create instance with ISO.

| rxtx_factor                | 1.0                                  |

| vcpus                      | 1                                    |

2nd, install system step by step with the ISO.

3rd, reboot after all done. Then it return to the installation page again!

I don't know why! I just want to create instance by ISO and start up it normally.

Does anyone know how to start up system normally ?

You have to use qcow2 or cloudinit to create cloud image. Then you have to upload that image to glance with proper Hypervisory supported parameter. Using ISO you can not provision instance..

It seems that openstack supports iso image to create instances. But my environment has some problem and it can not achieve that.

You cannot use any iso image directly untill the image supports virtio driver for lan and hdd , You need to create a qcow2 image via virtual machine manager and specify the virtio driver/device for lan and hdd hardware , once these drivers are imported by vm , you can import the qcow2 image in openstack as a image to be spanned as instance.

Could you please tell me how to make linux iso image to support virtio driver? I know the windows iso images need virtio dirver. However, I used linux iso images. Thanks a lot.
