KVM Virtualization-Basic building

1, the Physical machine system installation (hard disk for 300g+300g):

centos6.5 64-bit, does not install the desktop environment, the default run level is 3 partition:/boot 128Mswap 8g/20g/data1 first hard disk remaining space/data2 the second hard disk full space with minimal installation + the following package: Basesystem-- basedevelopment--Development tools to configure DNS to determine the system time with the Beijing time synchronization server to allow command restart (auto-complete), if required self-test, manual press F1, please remove the Machine self-test) BIOS on VT function

2. Installation of the KVM environment:

Yum-y Install KVM python-virtinst libvirt tunctl bridge-utils virt-manager qemu-kvm-tools virt-viewer virt-v2v libguestfs -tools/sbin/service LIBVIRTD restartln-s/USR/LIBEXEC/QEMU-KVM/USR/BIN/QEMU-KVM

Create a network bridge: Cat/etc/sysconfig/network-scripts/ifcfg-br0

Device=br0type=bridgeonboot=yesbootproto=staticipaddr= Public network ipnetmask= public IP mask gateway= public IP Gateway

Modify the NIC information to connect the NIC to the bridge: cat/etc/sysconfig/network-scripts/ifcfg-em1

Device=em1bridge=br0onboot=yesbootproto=none

To restart the network card:

Service Network restart

To view the Network bridge:

[[email protected] data1]# Brctl Show bridge name Bridge ID STP enabled INTERFACESBR0 8 000.d4ae526e935a no em1virbr0 8000.525400efec1a Yes Virbr0-nic

Now that the KVM environment is installed, the next new virtual machine installs the operating system

3, upload ISO (slightly)

4. Create a virtual machine:

To create a disk:

Qemu-img create-f qcow2 centos01.img 120gvirt-install--name=centos01--ram 4096--vcpus=2--disk path=/data1/centos01.i Mg,format=qcow2,si

--name specifying the virtual machine name

--ram allocates memory size.

--vcpus allocates CPU cores, with the largest number of CPU cores in the physical machine

--DISK Specifies the virtual machine image, size specifies the allocation size in units of G.

--network network type, used here is the default, the general use should be bridge bridging.

--accelerate acceleration

--cdrom specifying the installation image ISO

--VNC Enable VNC remote Management, the general installation system will be enabled.

--VNCPORT Specifies the VNC monitoring port, the default port is 5900, and the port cannot be duplicated.

--vnclisten Specifies the VNC bound IP, the default binding 127.0.0.1, this is changed to 0.0.0.0

If no accident, the system will start the 5910-terminal

5, install the operating system (slightly)

6, the Daily management of KVM:

View KVM list: Virsh list--all

Start Kvm:virsh start centos01

Close Kvm:virsh shutdown centos01

Force off Kvm:virsh Destroy CENTOS01

Pause Kvm:virsh Suspend centos01

Resuming Kvm:virsh resume Centos01

Clone Kvm:virt-clone-o centos01-n centos02-f/data1/centos02.img

Edit KVM Configuration: Virsh edit centos01

To delete a VNC port:

Virsh edit Centos01, after opening the XML, delete the following configuration:

<graphics type= ' vnc ' port= ' 5910 ' autoport= ' no ' listen= ' 0.0.0.0 ' > <listen type= ' address ' address= ' 0.0.0.0 '/&G    T </graphics>

To set up KVM boot autostart:

Vrish autostart centos01
