Where is the RHEL7 kernel source code installed?

Question

I install the Linux kernel source code RPM:

[root@localhost ~]# rpm -ivh kernel-3.10.0-229.el7.src.rpm
warning: kernel-3.10.0-229.el7.src.rpm: Header V3 RSA/SHA256 Signature, key ID f4a80eb5: NOKEY

The installation process seems success, but using rpm -ql kernel-3.10.0-229.el7.src command can't find where the source code is installed:

[root@localhost ~]# rpm -ql kernel-3.10.0-229.el7.src
package kernel-3.10.0-229.el7.src is not installed

Where is the RHEL7 kernel source code installed?

Update: rpm -qa | grep kernel command ouput:

[root@localhost ~]# rpm -qa | grep kernel
kernel-headers-3.10.0-229.el7.x86_64
kernel-devel-3.10.0-229.el7.x86_64
kernel-3.10.0-229.el7.x86_64
kernel-tools-libs-3.10.0-229.el7.x86_64
abrt-addon-kerneloops-2.1.11-19.el7.x86_64
kernel-tools-3.10.0-229.el7.x86_64

Solution

Source packages are not added to the rpm database, so they will not show on query.

Probable location is ~/rpmbuild/{SOURCES,SPECS} with SOURCES containing the package sources and distribution patches while the SPECS subdirectory containing the .spec file being used to build the package (see rpmbuild (8) man page for details).

If you can't find the sources there, than reinstall with the -vv option to check the location if it's overwritten:

$ rpm -ivvh kernel-3.10.0-229.7.2.el7.src.rpm

Add output of "rpm -qa|grep kernel", just to show what is actually installed ?

[Aaghaz]

try rpm -ql kernel-3.10.0-229.el7.x86_64

kernel-devel is actually not full source code, but contains enough to compile modules.

There's actually only one warning that is repeated for every file that is created. The rpm says that the files must belong to user "builder" (the account used by redhat for developing). Since this user does not exists in the current system the files will be created as the default user "root" or if you run the command as normal user, the user running the command and display a warning.
