After installing CentOS 7.5 and installing package qemu-kvm-ev
I can't install KVM on x86_64 arch:

command "yum -y install perf qemu-kvm-ev qemu-kvm-tools-ev virt-top"
failed with error code 1 and such error message:

failure: repodata/repomd.xml from centos-qemu-ev: [Errno 256] No more 
mirrors to try.
http://mirror.centos.org/altarch/7/virt/x86_64/kvm-common/repodata/repomd.xml: 
[Errno 14] HTTP Error 404 - Not Found

=====================================================================
Is known time when this bug https://bugs.centos.org/view.php?id=14764
will be fixed and repository qemu-kvm-ev will work fine for CentOS 7.5 ?

I see your message "Packages landed on mirrors, we can close this
bug."
But this is not true, packages for x86_64 can't be found on the site:

http://mirror.centos.org/altarch/7/virt/

only aarch64 and ppc64le directories exists, and no x86_64 one.

Can you help me install qemu-kvm-ev on CentOS 7.5 on x86_64 arch?

P.S.

# cat /etc/redhat-release

I found workaround:

# diff -u CentOS-QEMU-EV.repo.old CentOS-QEMU-EV.repo

now all works fine.

But as I understand, this is bug and it should be fixed.

Something wrong with $contentdir variable,
it points to altarch for x86_64 $basearch.

can't reproduce on a fresh x86_64 installation. Adding Brian in case he has
a clue for this.
