Steps followed
1. Create a KVM external environment
Launch a centos 7 vm and install the following packages
```
yum install qemu-kvm libvirt libvirt-python libguestfs-tools virt-install
Systemctl enable libvirtd
systemctl start libvirtd
```
2. Edit the /etc/libvirtd/libvirtd.conf
```
listen_tls = 0
listen_tcp = 1
tcp_port = "16509"
auth_tcp = "none"
mdns_adv = 0
key_file="/etc/pki/libvirt/private/serverkey.pem"
cert_file="/etc/pki/libvirt/servercert.pem"
ca_file="/etc/pki/CA/cacert.pem"
3. Edit the /etc/sysconfig/libvirtd
`LIBVIRTD_ARGS="--listen"' `
```
4. Launch a vm with the following command
`virt-install --virt-type=kvm --name centos8 --vcpus 2 --ram 2048
--os-variant=rhel8.0 --cdrom=/var/lib/libvirt/images/centos8.iso
--network=default --disk size=16`
5. Shutdown the vm
`virsh shutdown <name >
`
