In centos, we can use Yum to download or update the RPM package, but only a part of the RPM package is provided in the standard source (repository), although in most cases, these packages are sufficient.
But sometimes you still need to download some other non-standard packages, such as qemu. Otherwise, you can only compile the corresponding packages by yourself, and this may not be what every user is willing to do.
The following website provides additional packages for installation.

The repoforge project maintains the RPM package for the following projects:
- Red Hat Enterprise Linux (RHEL)
