Description of problem:
module info shows the 'Default profiles' is 'default', but it should be 'common'

Version-Release number of selected component (if applicable):
Name             : virt
Stream           : 8.0.0
Version          : 820190227090827

How reproducible:
100%

Steps to Reproduce:
1. Prepare the repo for fast train virt, then run
# yum module info virt
Updating Subscription Management repositories.

Version          : 820190227090827
Context          : 9edba152
** Profiles         : common **

Actual results:
It shows the 'Default profiles' is 'default' which do not exists, it should be "common"

Expected results:
The 'Profiles' and 'Default profiles' both should be 'common'

Additional info:

Comment 1 Jeff Nelson 2019-03-01 16:12:43 UTC

Can't tell if this is due to how the module is defined or if this is a dnf issue. Assigning for further investigation/triage.

Comment 2 Danilo de Paula 2019-03-01 17:10:52 UTC

This is how it works:

module defines a bunch of profiles, but they don't have any special meaning (as far as I can tell).
There was this concept of a profile called 'Default', but it was dropped in favor of using one with no special meaning. In this case, 'common' profile.

Then, libmodulemd [1] has a list of modules with the information about what profile should be used as the default. This is consumed by dnf.
For virt:rhel, is the 'common' profile.

The problem is: libmodulemd doesn't have a definition for layered products.
I opened a ticket about this: https://projects.engineering.redhat.com/browse/RCM-52468

Comment 3 Danilo de Paula 2019-04-15 21:13:34 UTC

The repository is suppose to be working with a default profile set.

$ "dnf module install virt:8.0" should work.

Comment 4 yalzhang@redhat.com 2019-08-02 07:42:02 UTC

Checked on latest module for different streams including: 8.0.0.z rhel; 8.1.0 rhel; 8.0.0.z rhel av; 8.0.1 rhel-av; 8.1.0 rhel-av; 
The module info shows for profiles info is correct for all the streams: 
...
Profiles         : common [d]
Default profiles : common
...

And the module can be installed without specify the profile name as in comment 3.

Comment 7 yalzhang@redhat.com 2019-08-30 06:21:17 UTC

Check on latest virt:8.1 module:
# yum module info virt:8.1 
......
Name             : virt
Stream           : 8.1
Version          : 8010020190827203619
Context          : cdc1202b
Architecture     : x86_64
Profiles         : common [d]
Default profiles : common
...

And it can be installed without specify the profile name, which is expected, set the bug to be verified.
