What is a snapshot Snapshots can record the full state of a point-in-time virtual machine operating system and crawl the current system state through the Microsoft Volume Shadow Copy Service (Volume Shadow Copy Services) technology, and you can put all the states of a virtual machine at some point (memory, disk, network, files, etc.) crawled as a mirrored file, and at any later time, the actual state could be restored by
restrictions on the CPU support of the system itself.The operating system supports both Socket and Core CPUs, hyper-Threading is basically invisible to the operating system (in fact, you can know that Hyper-Threading is enabled through CPU parameters and other mechanisms). Therefore, HT can be simply understood as a core.The physical CPU (socket) and multi-Core CPU (multi-Core) supported by windows 2003 and other server operating systems are limited by the product version (standard, enterprise,

After installing the XenServer, we need to install our virtual machine on it, which requires an ISO image file, and under Xencenter, it is not possible to mount the ISO file in our computer directly like the VMware VSphere client, but we need to use our shared folder.
