If your processor supports vmx (
cat /proc/cpuinfo | grep vmx), you can
install QEMU/KVM for faster VMs.
yum install kvm kmod-kvm qemu libvirt service libvirtd start
You can now connect to the instance with
If virt-manager reports that you don’t have KVM support, check your BIOS and enable virtualization (VT for Intel processors) and power cycle the server. Then check if the kernel module is inserted properly:
lsmod | grep kvm # If not modprobe kvm modprobe kvm-intel
