CentOS 8 & IBM Red Hat 8 support QEMU & KVM
# yum groupinstall "Virtualization Host" # yum install virt-install # yum install virt-manager # yum install libvirt-nss # systemctl enable --now libvirtd
however note that IBM Red Hat say
while QEMU is an essential component of the architecture, it is not intended to be used directly on RHEL 8 systems, due to security concerns. Therefore, using
qemu-* commands is not supported by Red Hat, and it is highly recommended to interact with QEMU using libvirt.
so on centos 8 and ibm red hat 8 instead of qemu-* use these commands
$ virt-host-validate $ virt-install $ virt-manager $ virt-viewer $ virsh
and red hat developers also can refer to
