Fixed In Version:	yum-3.4.3-138.el7	Doc Type:	Bug Fix
Doc Text:	Cause: User tries to install a package that depends on another package which is allowed to be installed in multiple versions at once (via the installonlypkgs configuration option), and a newer version of that dependency is already installed. Consequence: Yum fails to install such a dependency, making the current transaction fail. Fix: Yum now gives correct instructions to RPM when it encounters such a dependency. Result: Yum now successfully installs packages with such dependencies.	Story Points:	---

Complete!

# rpm -q kernel-devel
kernel-devel-3.10.0-123.el7.x86_64
kernel-devel-3.10.0-229.14.1.el7.x86_64

But, when it's required as a dependency of a package installation,
yum rejects to install kernel-devel package since the newer package is already installed. 

The customer's custom rpm depends on the old kernel-devel, and they want it to install kernel-devel upon dependency resolving in yum command.

Version-Release number of selected component (if applicable):
Red Hat Enterprise Linux 7.2

How reproducible:
Always

Steps to Reproduce:
1. install RHEL7.2 and confirm kernel-devel is installed.
2. configure RHEL7.1 yum repository
3. install a testa package I attached.

# yum install testa-1.0-1.el7.x86_64.rpm

Actual results:
The older kernel-devel is not installed, though it's found as a dependency.
Because a newer kernel-devel is installed.

Expected results:
The older kernel-devel is installed to resolve the dependency without any error, even if a newer kernel-devel package is installed.

Additional info:

I will attach the testa package for testing, and proposed patch, which the customer verified.
