No way to mention flavor details for KB proxy server

[chinasubbareddy mallavarapu]

While setting kloudbuster for openstack with ceph as backend , we are having issues to launch KB proxy node as flavor says root disk as zero but image expects more than 3GB.

there is no way we can mention flavor details for KB proxy node hence running tests failing to launch KB proxy vm with below error .

Error: Failed to perform requested operation on instance "vm2", the instance has an error status: Please try again later [Error: Build of instance df6816d2-f39b-4ed3-9175-60dd9b075f69 aborted: Volume c2ea0d78-5cb3-4a61-ad4d-c155e1f5b0e6 did not finish being created even after we waited 12 seconds or 5 attempts. And its status is error.].

by default if flavor has zero as root disk , it will try to create 1GB volume and that will not be sufficient for KB proxy vm to launch.

The flavor for the proxy VM is hardcoded and set to

                proxy_flavor = {
                    "vcpus": 1,
                    "ram": 2048,
                    "disk": 0,
                    "ephemeral": 0
                }

This should be sufficient for the VM Image provided with kloudbuster (we never had any issue running this on multiple openstack pods).
A disk of zero means it will create a root disk with the default size specified by the image and sufficient for it s need (not necessarily 1GB),

Your log above seems to be related to a manual launch of the VM image?

Can you provide the exact/complete output when running kloudbuster?

it would be helpful if we can make proxy vm flavor also configurable like server/client vms .

this problem comes when openstack(newton ) setup has bootable volumes enabled for boot from image option specially from horizon.

In the instance launcher, when selecting Image or Image snapshot as boot source, the Create volume option is set to yes by default and size of the volume will be 1GB, that is where vm launch gets failed with kloudbuster image(since it expects more than 1GB space ).

but this is the problem only from horizon not from CLI.

Here is the bug:

This is possible and would require extending the kloudbuster configuration file.
You are welcome to contribute to this patch, otherwise will need that someone has the time to add it.

most of the times when we try from kloudbuster, it will launch the vm but few times it will fail with above issue .

Thanks for picking this up, could you please tell me the timeframe of your commit as I am planning the next release (7.1.0) and it needs to go out soon (hopefully by end of this week at the latest).
If not ready I can always pull another release later (7.1.1).

sine i am new , i may need some time here, i will push this by 7.1.1
thanks .

[Alec Hothan (ahothan)]

no problem, we will get it on the next release after it gets committed.
Please do not hesitate to ask questions and do not spend too much time on this, it should be straightforward solution (few lines of diffs)
