Installing KVM on centos6.7, creating VMS in bulk

Lab environment: Dell r710 Linux system uses centos6.7

Memory 32G, HDD 800G

Server Host: 172.18.204.1

Kickstart file Host: 172.18.11.115

]# modprobe KVM

]# lsmod |grep KVM

You can continue as shown below:

Verify that the following files exist

]# ls /DEV/KVM

To turn off SELinux:

]# vim /etc/sysconfig/selinux

Selinux=dsabled

]# Service NetworkManager Stop

]# Chkconfig NetworkManager off

]# yum-y Install libvirt install QEMU-KVM virt-manager virt-viewer virt-insatll qemu-kvm-tools KVM PYT Hon-virtinst

]# Service LIBVIRTD Start

]# Chkconfig LIBVIRTD on

To create a physical bridge:

]# Virsh Iface-bridge em1 br0

]# mkdir-pv/data/vms/images/test/

]# virt-install--name=centos6--os-type=linux--os-variant=rhel6--ram 1024x768--vcpus=2--disk path=/data/vms/images /test/test.img,format=qcow2,size=80,bus=virtio--accelerate--location http://172.18.0.1/ cobbler/ks_mirror/centos-6.7-x86_64/ --vnc--vnclisten=0.0.0.0--network bridge=br0,model=virtio-- Noautoconsole

]# Virt-manager

The graphics window appears:

The above one virtual machine is created, in this case, the premise is that the network has Pxe+cobbler automatic installation system http://172.18.0.1/cobbler/ks_mirror/CentOS-6.7-x86_64/

On the basis of the above, you can also use the script to create the virtual machine in bulk, and provide a local kickstart installed partition file, according to the secondary file for the virtual machine automatically partition:

On 172.18.11.115:

A Web server is provided and the kickstart file can be accessed;

]# yum-y Install httpd

]# VIM/VAR/WWW/HTML/CENTOS6

]# chmod +x createvm.sh

]# Bash-n createvm.sh

The example above is to create 8 virtual machines with the name centos6-24 to centos6-30, the number specified for the parameter 1 for the memory set to the number specified for the 1024,CPU number of parameters 2 to 2 cores, The kickstart file points to the file provided in the 172.18.11.115;

]# createvm.sh 1024 2

At this point, 8 virtual machines are created automatically.
