KVM Clone Virtual Machine

KVM Clone Virtual Machine

Introduction to Virt-clone Effect

Virt-clone is primarily used to clone KVM VMs and is available through Options, General Option, Storage configuration, Networking configuration Different options to make some special definitions of the new virtual machine.

1 Viewing KVM virtual machines

[[email protected] ~]# Virsh List--allId    Name                           ' state '    centos6u5_1                          Centos6u5                      Running

2 Turn off the selected virtual machine

[[Email protected] ~is ~]# virsh List--allId    Name                           State     Centos6u5_1                     -     centos6u5                      shut off

This way. If you do not close the KVM virtual machine then the direct cloning will be an error, for example: Error Domain with devices to clone must is paused or shutoff.

3 Cloning a virtual machine

[Email protected] ~]# virt-clone--connect=qemu://system-o centos6u5-n centos6.5_clone-f/opt/qemu-img /centos6u5_clone.img'centos6u5_clone.img'                                               |   -XX:  $'     centos6.5_clone  ' created successfully.

4 View all virtual machines list

[Email protected] ~]# Virsh List--allIDs    Name                           State    centos6u5_1                    -      Centos6.5_clone                 -     centos6u5                      shut off

5 Starting a new cloned KVM virtual machine Centos6.5_clone

[Email protected] qemu]# Virsh start Centos6.5_clone

Note: Virsh edit centos6.5_clone Change the domain name path

Note: There may be a conflict with the MAC address after cloning, delete the configuration of the eth0 in/etc/udev/rules.d/70-persistent-net.rules, then change the eth1 to eth0, and modify the Ifcfg-eth0 Mac, Confirm that the MAC address is the same in the two configuration files.

6 KVM Virtual Machine cloning complete

[[email protected] qemu]# Virsh List--allId    Name                           ' state '    centos6u5_1                      -     centos6.5_clone                -     centos6u5                      shut off
