check if hardware is enabled with virtualization
egrep -c '(vmx|svm)' /proc/cpuinfo

install KVM
sudo dnf install qemu-kvm libvirt libvirt-client virt-top virt-install virt-manager virt-viewer libguestfs-tools

sudo systemctl start libvirtd
sudo systemctl enable libvirtd

sudo systemctl status libvirtd

default path of ISO when downloaded in my machine is
Downloads/Github/ copy it to /var/lib/libvirt/boot/

AlmaLinux-9-latest-x86_64-dvd.iso
download the iso with
sudo virt-install --name AlmaLinux-server --ram=2048 --vcpus=2 --cpu host --hvm --disk path=/var/lib/libvirt/images almalinuxservervml,size=20 --cdrom /var/lib/libvirt/boot/AlmaLinux-9-latest-x86_64-dvd.iso --graphics vnc
