1: Briefly describe the concept of virtual machines.
It is a set of programs running on a computer that simulates the functions of computer hardware and provides an independent computer environment for other software programs. For these software programs, a virtual machine is a complete set of computer hardware.
2: What are the virtual machine platform products?
(1) vmware workstation (2) VMware vsphere (3) virtualbox (4) hyper-v (5) xendesktop and xenserver
3: Illustrates the difference between the sojourn architecture and the native architecture.
The sojourn architecture requires two operating systems; the native architecture requires only one operating system
4: Under what circumstances will the memory capacity of the virtual machine be modified? When the memory capacity
itself is not enough and additional memory is needed
5: Under what circumstances will the suspend virtual machine function be used?
When resuming a virtual machine, the application that was running before the suspension will resume its running state without changing its content
6: The virtual machine has added a CD image, but the image is not read after booting, why?
The bios of the virtual machine is not set to boot from the CD, or the image is not a bootable version.
7: How to switch between host and virtual machine?
ctrl+alt
8: What is the default path for accessing wmware shared folders?
\vmware-host\shared folders
9: What is the difference between a startup snapshot and a shutdown snapshot?
Snapshots are divided into shutdown snapshots and startup snapshots. The shutdown snapshot only establishes a point-in-time link, so it occupies a relatively small hard disk capacity. The boot snapshot is a copy of the current host state, which takes up a lot of hard disk space.
10: What is the difference between the two cloning methods?
Creating a profile clone will occupy the smallest disk space, but will use the files of the original virtual machine, so the original virtual machine cannot be deleted; creating a complete will create a complete virtual machine file.
