invalid image information in resource metadata

[jiang, yunhong]

Currently all image informatio in resource metadata is empty.

Current the implementation try to get all image data through instance attribute, however, the image information is located in instance.image, and the kernel_id and ramdisk_id is not included in the instance object at all.

After checking related code, I think this issue happens during the remove_db. The database includes the image_id and other information, while is changed in novaclient through the viewbuilder.

[jiang, yunhong (yunhong-jiang)]

I have a concern to changes required on nova to support kernel_id and ramdisk_id. The concern is, it will need to add 'kernel_id' and 'ramdisk_id' to the server details request. This is in fact a API changes, so not sure how strict nova is for the API changes.

The patch to add the ramdisk_id and kernel_id is simple as followed one, but a lot of test cases need be updated since these test case will check the key in the return value also.

So just want do discuss how important/priority to add back the kernel_id/ramdisk_id back to the meter.

    Fix image_id in instance resource metadata

    Originally the image property in instance resource metadata is correct
    since instance information is fetched from db access.

    After switching to nova client api, these information is lost
    since the returned data format from nova client is different with db
    access result.

    Image ref and image url is fixed with this patch while kernel_id and
    ramdisk_id should be fixed in nova side.

    For bug 1090310
