KVM virtualization configuration process

The overall idea is that VNC is connected to a physical machine to facilitate graphical Management of KVM.

After the virtual system is installed, you can manage the IP address of the subsystem through SSH.

VNC Installation

Yum install tigervnc-Server

Vim/etc/sysconfig/vncservers modify two rows

Vncservers = "1: Root"

Vncserverargs [1] = "-geometry 1024x768-nolisten TCP"

Run vncpasswd in the root account to set the VNC password for root login.

Cd ~ /. VNC/xstartup

Modify the "TWM" at the end of the document to gnome-session or startkde.

Service vncserver start

After completing the previous step, you can connect to the physical machine in a graphical manner.

KVM Installation

Yum install KVM kmod-KVM-qemu-IMG libvirt Python-kernel inst virt-manager virt-Viewer bridge-utils-y

Chkconfig NetworkManager off

Chkconfig libmongod on

Service NetworkManager stop

Service libmongod start

Vim/etc/sysconfig/network-scripts/ifcfg-br0 (all addresses are the same as eth0)

Device = br0

Bootproto = static

Broadcast = ***

Ipaddr = ***

Netmask = 255.255.255.0

Onboot = Yes

Networking_ipv6 = No

Gateway = ***

Type = Bridge

Dns1 = 202.106.0.20

Dns2 = 114.114.114.114

Vim/etc/sysconfig/network-scripts/ifcfg-eth0

Add a row at any location. Bridge = br0: Save and exit.

Service Network restart

Reboot

-----------------------

The connection address for installing VNC on the client is IP: 1

The basic running level of the physical machine can always be init 3, without affecting the graphical Management of VNC

Verwer graphical management of physical machines. When VNC is not needed, service vncserver stop
