Brief introduction:

VMware Workstation (Chinese name "Weirui Workstation") is a powerful desktop virtual computer software, which provides users with the best solution to run different operating systems on a single desktop at the same time, and to develop, test and deploy new applications. VMware Workstation can simulate a complete network environment on a physical machine, as well as a portable virtual machine, which has better flexibility and advanced technology than other virtual computer software on the market. For IT developers and system administrators in enterprises, VMware has become an indispensable tool for virtual networks, real-time snapshots, dragging shared folders, supporting PXE and so on.

Features:

VMware Workstation allows the operating system (OS) and applications (Application) to run inside a virtual machine. A virtual machine is a discrete environment that runs the host operating system independently. In VMware Workstation, you can load a virtual machine in a window that can run its own operating system and applications. You can switch between multiple virtual machines running on your desktop, share virtual machines over a network (such as a corporate LAN), suspend and restore virtual machines, and exit virtual machines without affecting your host operations and any operating systems or other running applications.

Cloning reason

We know that it takes a lot of time to install the linux system manually, so, usually, half of our study uses replication and cloning to create virtual machines. The reason is that both replication and cloning can quickly allow us to have a virtual machine without taking too much time.

VM virtual machine cloning (there are three VM virtual machine cloning methods) (1) Manual cloning * * We use test01 and cloned test02 to demonstrate * * test01-- > test02 step 1: enter the xml master configuration text of the test01 virtual machine Copy the xml file under the component directory: cp test01.xml test02.xml step 2: copy the disk file under the raw disk file directory of the test01 virtual machine: cp centos.raw test02.raw step 3: modify the configuration file and re-produce a virtual machine (definition) Vim test02.xml modifies the name Delete uuid, delete mac definition virtual machine complete manual cloning virsh define test02.xml (2) Link cloning step 1: let's turn off test01 and test02 above step 2: link the qcow2 disk format to test01's raw disk file Change the name to test02.qcow2 qemu-img create-f qcow2-b centos.raw test02.qcow2 View qemu-img info test02.qcow2 step 3: modify the disk file of test01 (change back to default) test02 (disk change to link file qcow2) step 4: redefine test01 test02 (3) complete cloning-step 1: virt-clone-- auto-clone-o test02-n test03
