Quickly build KVM and install Linux systems

1. Installing the KVM kernel and LIBVIRTD related components

Yum-y Install KVM python-virtinst libvirt tunctl bridge-utils virt-manager qemu-kvm-tools virt-viewer

2. Load the KVM Runtime module

[Email protected] ~]# modprobe kvm[[email protected] ~]# modprobe-ls |grep kvmkernel/arch/x86/kvm/kvm.kokernel/arch/ X86/kvm/kvm-intel.kokernel/arch/x86/kvm/kvm-amd.ko

3. Create a physical bridge

VIRSH IFACE-BRIDGE ETH0 BR0 View Network [[email protected] ~]# ifconfigbr0        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           inet6 addr: fe80::20c:29ff:fec1:6256/64 scope:link           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1           RX packets:4925 errors:0 dropped:0  overruns:0 frame:0          tx packets:3937  errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:0           rx bytes:532933  (520.4  KiB)   TX bytes:13484199  (12.8 MIB) eth0      link  encap:ethernet  hwaddr 00:0c:29:c1:62:56             UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1           rx packets:377686 errors:0 dropped:0  overruns:0 frame:0          tx packets :110643 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000            RX bytes:507725096  (484.2 MIB)   TX bytes:66233641  (63.1  MiB)

4. Create a Virtual disk:

Qemu-img create-f qcow2/kvm/test003.img 5G

5. Create a virtual machine:

QCOW2 format [[email protected] ~]# virt-install--name test003--ram--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: [[email protected] ~]# virt-install--name test003--ram S=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
