Quickly deploy multiple systems using Hyper-V differential Disks

Traditional deployment of multiple virtual systems, or one installation, is a waste of time to directly copy the virtual hard disk to reset ISD, a virtual machine 10 Gb, four 40 Gb so it is a waste of time and space! Www.2cto.com
Use the differential disks provided by HV to save space and time. The most important thing is to facilitate the installation and deployment of the system multiple times in the future!
1. Install windows Server 2003 in a normal program, open the run dialog box, and enter syspre (this function must be vista or above, so it does not include the traditional XP and)
Click sysprep, select "New System Experience", select "general purpose" and "shutdown", and the system will automatically clean up relevant information. When the system is disabled, the master disk of the differential disk is created successfully! Cause of direct security. We recommend that you copy a VM disk to another location for future use.
Set this virtual disk to read-only, because any changes to the master disk may lead to decommission of the different disk !!! After the system is disabled, right-click the HV button and choose create hard disk, and select the name and parent hard disk of the differential disk, that is, the win2012 virtual hard disk we just created, click Finish and then create a virtual machine in the normal order. However, in the virtual hard disk option, select the new differential disk and click Finish to start the virtual machine. The system is installed as usual, after the restart, you can set the interface, which is much faster than the new installation.
In the same way, we can quickly deploy multiple virtual systems. In some experiments similar to Lync, we can run the whoami/all command. the SID of the created virtual machine is different from that of the created virtual machine, prevents unpredictable errors. Applications with different disks do not waste too much time and space, which is quite useful for testing environments.
