Unable to install virt-customize: error: yum -y install 'haproxy': command exited with an error

Tried multiple times on 4.2.latest and 4.5.latest but never managed to get this working

Can you suggest whats could be the problem

 One of the configured repositories failed (Unknown),
 and yum doesn't have enough cached data to continue. At this point the only
 safe thing yum can do is fail. There are a few ways to work "fix" this:
     1. Contact the upstream for the repository and get them to fix the problem.

     2. Reconfigure the baseurl/etc. for the repository, to point to a working
        upstream. This is most often useful if you are using a newer
        distribution release than is supported by the repository (and the
        packages for the previous distribution release still work).

     3. Run the command with the repository temporarily disabled
            yum --disablerepo=<repoid> ...

     4. Disable the repository permanently, so yum won't use it by default. Yum
        will then just ignore the repository until you permanently enable it
        again or use --enablerepo for temporary usage:

            yum-config-manager --disable <repoid>
        or
            subscription-manager repos --disable=<repoid>

     5. Configure the failing repository to be skipped, if it is unavailable.
        Note that yum will try to contact the repo. when it runs most commands,
        so will have to try and fail each time (and thus. yum will be be much
        slower). If it is a very temporary problem though, this is often a nice
        compromise:

            yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
Cannot find a valid baseurl for repo: base/7/x86_64

If reporting bugs, run virt-customize with debugging enabled and include
the complete output:

  virt-customize -v -x [...]

@ksingh7 It seems the problem is the lack of internet access on the VMs spawned in libvirt/kvm. This should be easy to fix. Try the following:

First check if you spin up a normal VM in kvm, like rhel7 or centos7, does the VM get internet access by default (i.e, without any manual intervention). If it doesn't try to check what's missing. May be DHCP is disabled on the libvirt network being used by libvirt. If DHCP is the problem, simply use the -N, --libvirt-oct (see README or --help for more details) option so the script creates a new libvirt network for your OCP cluster.

If internet access is fine for normal VMs, dig a bit more deeper by downloading centos cloud image and manually spinning it up to see why there is no internet access on the VM. You can use the following commands to test this out:

# Download the image to a tmp dir
mkdir /tmp/test
cd /tmp/test
wget https://cloud.centos.org/centos/7/images/CentOS-7-x86_64-GenericCloud.qcow2

# Setup image
virt-customize -a "./CentOS-7-x86_64-GenericCloud.qcow2" \
    --uninstall cloud-init --root-password password:test \
    --selinux-relabel --install haproxy --install bind-utils

# Install image as VM
virt-install --import --name vm-net-test --disk "./CentOS-7-x86_64-GenericCloud.qcow2" \
    --memory 1024 --cpu host --vcpus 1 --os-type linux --os-variant rhel7-unknown \
    --network network=default,model=virtio \
    --noreboot --noautoconsole

# Start VM
virsh start vm-net-test

If the virt-customize is failing, remove the the --install haproxy --install bind-utils from the virt-customize above and try again. Once the VM is started, login through the console (root password is set to test) and see what is the issue that is not letting this VM have internet access.
