Boxiang,
Yes, I just want to check with you about images_type.
Do we really need to change “images_type” to rbd from default, is it related to format convert?
You patch code should already be hit, as we failed with EB307 with below error msg you added in your patch.
if CONF.libvirt.images_type in ('rbd',):
if not CONF.force_raw_images:
msg = _("'[DEFAULT]/force_raw_images = False' is not "
"allowed with '[libvirt]/images_type = rbd'. "
"Please check the two configs and if you really "
"do want to use rbd as images_type, set "
"force_raw_images to True.")
raise exception.InvalidConfiguration(msg)
Below command is sent in my virtual multi-node environment, not in EB test environment.
[root@compute-0 instances]# rbd ls -p vms
rbd: error opening pool 'vms': (2) No such file or directory
rbd: list: (2) No such file or directory
[root@compute-0 instances]# ls
compute_nodes locks lost+found
Unfortunately, we have no whole test log.
@Lemus
Contreras, Cristopher J Need your help to provide complete logs tested by EB308
Thanks!

Hi Zhipeng and All,
First of all, I found in your nova.conf, images_type
= default
So I think you just use qcow2 imagebackend and the root disk is on your nova-compute node
not in vms pool of ceph storage. You can check that with command 'rbd ls -p vms'.
So that the creating vm process will not trigger my code in this patch
From the nova code, in nova/virt/images.py
def fetch_to_raw(): ->
convert_image(path_tmp, staged, fmt, 'raw') ->
cmd = ('qemu-img', 'convert', '-t', cache_mode, '-O', out_format)
So if the format of image is not raw, it will call qemu-img command to convert it to raw.
But after converting and check the format of image again, it is still not raw, so it raise
exception.
So we can check the nova-compute logs whether other error msgs exist or not.
BTW, can you check the base image's format under '/var/lib/nova/instances/_base'?
You can find the image in nova-compute container.

virt_type = qemu
I also did below convert command manually, it seems OK.
controller-0:~$ qemu-img convert -t none -O raw -f qcow2 cirros-0.4.0-x86_64-disk.img test1.img
controller-0:~$ qemu-img convert -t writeback -O raw -f qcow2 cirros-0.4.0-x86_64-disk.img test2.img

controller-0:~$ qemu-img info test2.img
image: test2.img
file format: raw
virtual size: 44M (46137344 bytes)
disk size: 13M
Need further check why in the code after convert, the image format is still qcow2.

Hi Boxiang,
Yes, my below patch can be abandoned, just need to remove “force_raw_images: false” in
stx/openstack-armada-app/stx-openstack-helm/stx-openstack-helm/manifests/manifest.yamll file since the default value is true currently.
https://review.opendev.org/#/c/691802/
I will modify my patch.
However, it is not related to current issue since this flag is set to true in the test.
The issue is just as error log mentioned below.
“ Image 70f74018-24f6-4d7d-8f99-2194a4449cfd is unacceptable: Converted to raw, but format is now qcow2 ”
We need check this point further.
Thanks!

Hi Zhipeng,
I have succeeded to create the vm in openstack upstream(master, code is two weeks ago) now. I deployed the environment with kolla-ansible(ceph as the backend storage).
In my nova.conf file, the section of libvirt is as followed:
[libvirt]
connection_uri = qemu+tcp://172.16.140.14/system
images_type = rbd
images_rbd_pool = vms
images_rbd_ceph_conf = /etc/ceph/ceph.conf
rbd_user = nova
disk_cachemodes = network=writeback
hw_disk_discard = unmap
rbd_secret_uuid = 5c79d567-e142-4ab4-87f6-0fdf53060ab9
virt_type = kvm
The default value of 'force_raw_images' in nova is True, so I did not set it as True again in my nova.conf file.
I use the min image cirros with qcow2 format and created the vm without volume which is created by cinder.
It's my image's info:
(nova-compute)[root@zbx-allinone /]# qemu-img info cirros-0.4.0-x86_64-disk.img
image: cirros-0.4.0-x86_64-disk.img
file format: qcow2
virtual size: 44M (46137344 bytes)
disk size: 12M
cluster_size: 65536
Format specific information:
compat: 1.1
lazy refcounts: false
refcount bits: 16
corrupt: false
So as you said, command qemu-img failed to convert the image from qcow2 to raw. BTW, is it a phenomenon that must recur now in STX?
Are there other error logs in nova-compute or other nova-* services?

主题：RE: [Starlingx-discuss] About EB verification for openstack train upgradeHi Boxiang and all,
In fetch_to_raw(),
After force convert image from qcow2 to raw, the format is still not raw, then throw below error.
It seems qemu-image convert image failed.

Hi Boxiang,
It should be an issue in nova train.
Error log is below:
build of instance 363dddce-7af6-4701-8cea-52630b91ebcf aborted: Image 70f74018-24f6-4d7d-8f99-2194a4449cfd is unacceptable: Converted to raw, but format is now qcow2'
You tried to fix this issue before in nova LP:
https://bugs.launchpad.net/nova/+bug/1816686
In your patch: https://review.opendev.org/#/c/640271 (This patch is already in train release now)
You added below commit message in the patch.
“When we import image into rbd, check the format of cache
images. If the format is not raw, remove it first and
fetch it again. It will be raw format now.”
However, it seems not work! Below code will throw error when image format is not raw and block the VM creation.
In nova/virt/images.py
def fetch_to_raw() è
if data.file_format != "raw":
raise exception.ImageUnacceptable(image_id=image_href,
reason=_("Converted to raw, but format is now %s")
Not sure if your patch fixed this issue or is there any regression introduced in nova code later.
Any comment from you?
I will check nova code further tomorrow and sync with you.
We may need a patch for nova☹
Thanks!

Hi Zhipeng,
The results are OK for Simplex, Duplex and Standard Local Storage, all Test Cases PASSED.
For Standard External Storage (2+2+2) there is a high quantity of Test Cases failing because we cannot launch instances. Here’s a sample output: http://paste.openstack.org/show/785641/ with the error that matches what is described on the launchpad.
Sanity summary for this specific configuration: http://paste.openstack.org/show/785655/
Please, let us know if you need additional details.
Thanks & Regards,
