1.3-KVM Installation Preparation

To do this, we need the CPU support virtualization, some machine support but not in the BIOS, this need to be opened beforehand.

1. VMware installation centos6.6 64 bit (slightly)

Here are a few things to note:

A. Memory to 2g

B. Disk to 50g, or separate disk for storage of virtual machine files

C. The most critical step, when creating a virtual machine, the CPU needs to be configured virtualization (tick virtualization Intel vt-x/ept or Amd-v/rvi (V))

2. Pre-install KVM preparations

A. clear iptables rules

Service iptables stop; Service Iptables Save

B. turn off SELinux

Sed-i ' s/selinux=enforcing/selinux=disabled/'/etc/selinux/config

Setenforce 0

3. Start installing KVM

A. check if your system supports virtualization

Grep-ei ' VMX|SVM '/proc/cpuinfo (or cat/proc/cpuinfo |egrep--color ' VMX|SVM ')

Supported if output content, where Intel CPU support will have VMX,AMD CPU support will have SVM

B. installing a virtualized package with Yum

Yum install-y KVM virt-* libvirt bridge-utils qemu-img

Description

KVM: The package contains a KVM kernel module that provides the KVM hypervisor in the default Linux kernel

Libvirts: Install the Virtual Machine Management tool and use commands such as Virsh to manage and control the virtual machine.

Bridge-utils: Set up network card bridging.

virt-*: Create, clone virtual machine commands, and graphical management tools Virt-manager

QEMU-IMG: Installs the QEMU component, uses the QEMU command to create the disk, and so on.

C. check if the KVM module is loaded

Lsmod |grep--color KVM

The normal should be:

Kvm_intel 55496 3

KVM 337772 1 Kvm_intel

If not, you need to perform

Modprobe Kvm-intel

Try it again without restarting it.
