Install KVM virtual machine on CentOS6.4 system
Remarks: The following operating instructions are transcripts summarized after experimental verification. Friends in need can refer to them. The following are based on theVMware12.5.2 virtual machine The experimental environment installed on the version.
一、InstallKVM
1. KVM requires a CPU Support (Intel VT or AMD SVM). Enter the command: egrep ‘^flags.*(vmx|svm)’ /proc/cupinfo, the following display: svm, it can be seen that the CPU model of my computer is AMD.
2. installkvm libvirted, enter the command:< /span>yum install kvm kmod-kvm qemu kvm-qemu-img virt-viewer virt- manager libvirt libvirt-python python-virtinst
< p>3. Startlibvirted
input command:
service messagebus start
service haldaemon start
service libvirtd start
chkconfig messagebus on
chkconfig haldaemon on
< p>chkconfig libvirtd on
4. Check if kvmis installed successfully, enter the command:virsh -c qemu:// /system list. Check if the kvm module is installed successfully, enter the command:/sbin/lsmod | grep kvm
Second, Configure the bridge
1. Enter the command:
vi /etc/sysconfig/network-scripts/ifcfg- br0
a、
DEVICE=br0
TYPE=Bridge
BOOTPROTO=static
BROADCAST=192.168.xxx< /span>.255
IPADDR=192.168.xxx .1
NETMASK=255.255.255.0
NETWORK=192.168.< span style="color: #ff0000;">xxx.0
ONBOOT=yes< /p>
< span style="font-size: 16px;">b,
vi /etc/sysconfig/network-scripts/ifcfg- eth0
DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes
BRIDGE=br0
< /p>
2. restart the network service to take effect
service network restart
3. Enter the command:echo 1> /proc/sys/net/ipv4/ip_forward #Internet access on the virtual machine span>
4. Check the bridged network
[[email protected] ~]# brctl show
bridge name bridge id STP enabled interfaces
br0 8000.842b2b74e1b6 8000.842b2b74e1b6 No eth0
virbr0 pan style=”font-size: 16px;”> 8000.000000> 8000. -size: 16px;”>br0is the bridged network card we configured,virbr0 is automatically configured by the system scriptNATNetwork Card
(1). input command:
yum install tiggervnc-server

rpm -q vnc tigervnc-server
Display successful installation

(2). input command:
vi /etc/sysconfig/vncservers
#Add one line

Four. CreateKVMVirtual Machine
#virsh-install
1, enter the virtual machine name span>
2, how much memory is allocated
3, the number of processors
4, this step can be entered directlyiso The location orurl
5, virtual machine typeKVM< /span>
6, define the location of the virtual machine disk image< br>
6, which bridge to specify or multiple bridges can be specified
7, additional console andKSFile
8, connect to the system Parameter
Parameter description Note that each line must have a space
-n Virtual machine name
< span style="font-size: 16px;">-r Allocation of virtual machine memory size
–vcpus Assign virtualcpuNumber
-c Mirror file location< /span>
–vnc –vncport=5901 –vnclisten=0.0.0.0 Launch the graphical installation interface
–virt-type Virtual machine mode
-f Virtual machine system file storage directory< /span>
-s allocate disk size (GB)
-w Networking (birdge bridge:br0/nat bridge:virbr0)
–os-type=’windows’ –os-variant=win2k3 InstallationwindowsThe most If you add this, it will report an error
virt -installAfter the tool installs the virtual machine, in the directory/etc/libvirt/qemu/Generate belowxmlConfiguration file
-s Used to specify the size unit of the virtual disk ForGB
-m Specify the hardware address of the virtual network card by defaultvirt-installAutomatically generate
-p Create virtual Machine
-l specify installation source
-x EXTRA, –extra-args=EXTRAWhen executing from“–location”The option to specify the location of the client installation, attach Add kernel command line parameters to the installer.
-v, –hvm Set up full virtualization
virt-install –name=centos6.3 –ram 1024 –vcpus=2 –disk path=/data0/centos- 6.3.x86_64.img.img,size=20–accelerate –cdrom /data0/CentOS-6.3-x86_64-bin-DVD1.iso–graphics vnc,listen=0.0.0.0,port=5920,–network bridge =br0 –force –autostart
After execution,netstat- nulpt | grep 5920 See if the port is enabled
Five ,KVMVirtual machine configuration
1. Created with the default wizardKVMVirtual machine, the disk file location cannot be modified. You can use the following command to create a disk file first
qemu-img create -f qcow2 win7.img 700G
inhome/vpsdirectory, create a virtual machine disk file
2. UseVirtual Machine ManagerCreate a virtual machine system< /span>
Find the system disk to be installed from the hard disk Mirror, for examplewin7.iso
p>
Here, be sure to select Customeize configuration before install < span style="font-family: 宋体;">, do the final customization before installation
Note: Need to modify< /span>2A place
a.add aInputdevice (EvTouch USB Graphics Tablet) (Many articles on the Internet are for introductionvi To modify the configuration file, I don’t recommend you to do that. It’s very troublesome. And the effect of my experiment is not so good! ),If you don’t add this device, you are inVNCIn the environment, you will find that the mouse is very awkward and will run around!
< /p>
b.Add one
span>Graphics device, and set the defaultDisplay VNC Delete (because the defaultVNC< /span>Monitor only127.0.0.1)
So far, the key parts are all configured. Start the virtual machine and check VNC Port number
The default port is 5900
OK That’s it! OurKVMvirtual machine has been successfully installed and is inKVM< span style="font-family: 宋体;">Uploaded successfullyWIN7 GHOST.
