Quickly build KVM and install Linux

1. Install KVM kernel and libmongod Components
Yum-y install kvm python-stronginst libvirt tunctl bridge-utils virt-manager qemu-kvm-tools virt-viewer

2. Load the KVM operating Module
[Root @ localhost ~] # Modprobe kvm
[Root @ localhost ~] # Modprobe-ls | grep kvm
Kernel/arch/x86/kvm. ko
Kernel/arch/x86/kvm/kvm-intel.ko
Kernel/arch/x86/kvm/kvm-amd.ko

3. Create a physical Bridge
Virsh iface-bridge eth0 br0
View Networks
[Root @ localhost ~] # Ifconfig
Br0 Link encap: Ethernet HWaddr 00: 0C: 29: C1: 62: 56
Inet addr: 192.168.150.136 Bcast: 192.168.150.255 Mask: 255.255.255.0

4. Create a Virtual Disk:
Qemu-img create-f qcow2/kvm/test003.img 5G

5. Create a virtual machine:
Qcow2 format
[Root @ localhost ~] # Virt-install -- name test003 -- ram 512 \
-- Vcpus = 1 -- disk path =/kvm/test003.img, size = 5, format = qcow2, bus = virtio \
-- Accelerate -- cdrom/tmp/CentOS-6.6-x86_64-minimal.iso \
-- Vnc -- vncport = 5910 -- vnclisten = 0.0.0.0 \
-- Network bridge = br0, model = virtio -- noautoconsole
Raw format:
[Root @ localhost ~] # Virt-install -- name test003 -- ram 512 \
-- Vcpus = 1 -- disk path =/kvm/test003.img, size = 5, bus = virtio \
-- Accelerate -- cdrom/tmp/CentOS-6.6-x86_64-minimal.iso \
-- Vnc -- vncport = 5910 -- vnclisten = 0.0.0.0 \
-- Network bridge = br0, model = virtio -- noautoconsole

6. VNC connection

Getting started with Linux: KVM for Virtual Machine experience

RHEL6 KVM virtualization creates a bridge NIC-Bridge

RedHat Linux KVM Virtual Machine bridging

Installation/bridging settings of KVM in CentOS 5.6/virtual machine creation and operation

The/bin/qemu-KVM problem cannot be found when the kvm virtual machine is installed with libvirt In Ubuntu.
