Cannot get latest-version package from multiple yum repos

Question

There are two rpm repos in my CentOS 8.1.1911. Details are as follows:

# virt-1.repo
[appstream]
name=CentOS Linux 8-stream - AppStream
baseurl=http://mirrors.ustc.edu.cn/centos/8-stream/AppStream/$basearch/os/
gpgcheck=0
enabled=1

# virt-2.repo
[centos-advanced-virtualization]
name=CentOS Linux 8-stream - Advanced Virtualization
baseurl=http://mirrors.ustc.edu.cn/centos/8-stream/virt/$basearch/advancedvirt-common/
gpgcheck=0
enabled=1

The two repos both contain the package libvirt, and there are newer one in the repo centos-advanced-virtualization. My operation is as follows：

yum clean all && yum makecache
yum list libvirt --showduplicates, but I get the older one from appstream

# yum list libvirt --showduplicates

remove appstream, mv virt-1.repo virt-1.repo.bak && yum makecache
yum list libvirt --showduplicates, and I can get the newer one from centos-advanced-virtualization

# yum list libvirt --showduplicates

So, why can't I get the newer one at the beginning? Did I miss something?

You should have been keeping the system up to date the entire time it has been up! Running without installing updates is not supported on CentOS. — Michael Hampton, Sep 26 '21 at 10:01
Hi Michael. I've upgrade my CentOS to latest version (CentOS Stream 8), but this problem is still there. — freshMan, Sep 27 '21 at 09:36

I solved this problem from here:

The major reason why DNF wants to install MariaDB from AppStream is that it has a preference for modular packages. Which means, that if specific packages (names) or virtual provides are part of a module, and there are packages with the same names available from other repositories and they are not part of the module, then DNF will always want to install packages from the modular repository.

So, that's why I can't get the latest-version libvirt package. After updating my virt-2.repo as follows, everything is fine:

# virt-2.repo
[centos-advanced-virtualization]
name=CentOS Linux 8-stream - Advanced Virtualization
baseurl=http://mirrors.ustc.edu.cn/centos/8-stream/virt/$basearch/advancedvirt-common/
gpgcheck=0
enabled=1
module_hotfixes=1

I can get latest-version libvirt:

# yum list libvirt --showduplicates
