=============================================

Iv. installation of KVM virtual machines

Create an ISO image and a virtual machine installation directory

Mkdir-p/root/iso

Mkdir-p/DATA/KVM

Upload the ISO image file to the/root/iso directory and use the Centos-6.6-x86_64-bin-dvd1.iso

This adoption is pushed from other servers (the 100m/s,4.5g image file in the cluster intranet is passed about 40 seconds):

Scp-p30124/home/ywliyq/iso/centos-6.6-x86_64-bin-dvd1.iso [email protected]: ~

Method One: Installation of the KVM virtual machine (Xshell under the Virt-manager GUI)

Xshell cannot open Virt-manager's graphical interface,

First, installing Xshell is not possible, you need to install Xmanager

Second, after installing the Xmanager, open the Xshell, in the connection properties of tunneing, check the Forwarding X11 connection to option, you can open the Virt-manager graphical interface normally.

Note: After entering the installation interface, there will be a confusion of keyboard layout, the following is the workaround:

The keyboard confusion solution when KVM remotely manages guest machines via Virt-manager

First, Virt-manager Way (recommended)

If you want to avoid this, add a field to the keyboard layout when you use the Virt-install installation

--keymap=en-us

In the state of the virtual machine shutdown, select the appropriate virtual machine via the Virt-manager interface:

Open-->details-->display vnc-->keymap-->en-us

Save and then start the virtual machine.

Second, the command line mode

Close the virtual machine that you want to adjust, edit the virtual machine configuration file

#virsh edit ' your VM name '

Locate the following fields in the configuration file:

<graphics type= ' vnc ' port= '-1 '/>

After adding the language layout of the keyboard as follows:

<graphics type= ' vnc ' port= '-1 ' keymap= ' en-us '/>

After saving exits, reload the virtual machine configuration file

#virsh create/etc/libvirt/qemu/' your VM name '. xml

Configuration modifications finish starting the virtual machine

Start the installation and automatically enter the installation interface

650) this.width=650; "src=" Http://s1.51cto.com/wyfs02/M00/7F/3B/wKioL1cXRQTQ87xdAAeZITjoDUo159.png "title=" 3de237d7-32ab-4c0d-9a8c-266e4ec49358.png "alt=" Wkiol1cxrqtq87xdaaezitjoduo159.png "/>

And then the usual way of installation.

After the system is completed, the corresponding basic optimization needs to be done
