Description Brent Baude 2017-07-15 00:28:13 UTC 
The F26 AH and Cloud images will not provision on Azure due to a missing udf kernel module.  The udf kernel module is in the kernel-modules-extra.

As of cloud-init-0.7.9, the WALinuxAgent is not needed for provisioning on Azure.  The F26 AH and Cloud images should theoretically be able to boot on Azure now.  However, vm boot process with cloud-init, we have to load a cdrom device with the azure/cloud-init metadata on it.  In Azure, that cdrom device uses a udf filesystem.  Unfortunately the udf kernel driver is in the kernel-modules-extra package and is not available on the base images.  The mount fails and therefore fails the attempt to use cloud-init's data source.

Please consider moving the udf driver from kernel-modules-extra to main.
Comment 1 Laura Abbott 2017-07-17 15:57:00 UTC 
The udf module should just be in kernel modules and not kernel-modules-extra. can you double check?

She seems to be right:

```
[vagrant@vanilla-f26atomic ~]$ sudo modprobe udf                                                                                                                                                                  
[vagrant@vanilla-f26atomic ~]$ lsmod | grep udf
udf                    94208  0
crc_itu_t              16384  1 udf

Comment 3 Dusty Mabe 2017-07-17 19:21:30 UTC 
ok me again - I think brent was trying both of our images we put out for clouds. We have cloud base and atomic host. 

The cloud base image does not have kernel-modules installed at all, which seems to work for most cloud environments.

```
$ rpm -qa | grep kernel
kernel-headers-4.11.9-300.fc26.x86_64
kernel-core-4.11.8-300.fc26.x86_64
```

Atomic Host does have the kernel-module package installed because the atomic host ostree has to support both cloud environments and bare metal (various hardware) environments. I guess the only way to solve this for cloud base is to make the kernel module not be a module and be compiled in.
Comment 4 Laura Abbott 2017-07-17 19:58:56 UTC 
We can have modules in kernel-core as well. I made a scratch build https://koji.fedoraproject.org/koji/taskinfo?taskID=20583661 that should keep udf in the kernel-core package.

Thanks - i think brent went AFK for a week this morning. I'll build an image for him and gather some feedback from him when he gets back.
Comment 6 Dusty Mabe 2017-07-21 20:53:07 UTC 
Here is an ISO with the new kernel-core in it:  https://dustymabe.fedorapeople.org/f26-kernel-core-udf.qcow2

```
[fedora@cloudhost ~]$ rpm -q kernel-core
kernel-core-4.11.11-300.rhbz1471314.fc26.x86_64
[fedora@cloudhost ~]$ lsmod | grep udf
[fedora@cloudhost ~]$ modprobe udf
modprobe: ERROR: could not insert 'udf': Operation not permitted
[fedora@cloudhost ~]$ sudo modprobe udf
[fedora@cloudhost ~]$ lsmod | grep udf
udf                    94208  0
crc_itu_t              16384  1 udf
```
Comment 7 Brent Baude 2017-07-24 18:59:59 UTC 
Dusty,

Ill be back 7/31.  Is that an ISO or a bootable image?  The latter is the preferred.

it's a bootable qcow
Comment 9 Brent Baude 2017-08-03 15:42:35 UTC 
This did the trick.  I'll defer to you guys on how to implement it

thanks laura, according to brent that worked. Could we move the udf module to kernel-core?
Comment 11 Laura Abbott 2017-08-03 18:45:28 UTC 
I pushed the commit to F26 and rawhide. This will show up in the next builds.
