It's Virtualization with KVM

It's Virtualization with KVM ( Kernel-based Virtual Machine ) + QEMU. This requires that the CPU on your computer which has a function Intel VT or AMD-V.
[1]	Install KVM.

[root@dlp ~]#  yum -y install qemu-kvm libvirt virt-install bridge-utils # make sure modules are loaded [root@dlp ~]#  lsmod | grep kvm  kvm_intel 138567 0 kvm 441119 1 kvm_intel [root@dlp ~]#  systemctl start libvirtd  [root@dlp ~]#  systemctl enable libvirtd

[2]	Configure Bridge networking for KVM virtual machine. Replace the interface name "eno16777736" for your own environment's one.
