Virtualization support is usually disabled in bios and must be enabled.
For Intel CPU, we can run the following command to check whether virtualization is supported.

386, it is the CPU level.
I586-is a 586-level computer, including the first generation of pentum mmx cpu, AMD K5, and K6 system CPU (socket7 pin.
I686-pentum 2 after the Intel system CPU and K7 after the CPU level belongs to this 686 level.
You can query your CPU level through the/proc/cpuinfo file.
II. View CPU information
We can view CPU information through the/proc/cpuinfo file.
[Root @ qs-wgdb-1 proc] # more/proc/cpuinfo
Processor: 0
Vendor_id: GenuineIntel
Cpu family: 6
Model: 44
Model
Check the memory information, CAT/proc/meminfo. Similarly, check the CPU information. CAT/proc/cpuinfo sometimes has such questions. For example, if the 4-core CPU is a 2-core CPU * dual-core, or 1 CPU * quad core? There is a simple method: the number of processor, the number of cores, and the number of CPUs, depending on the physical ID + 1 of the last Processor
For example:
processor : 0vendor_id : GenuineIntelcpu family : 6model : 23model name : Pentium(R) Dual
course, we will not say that it is perfect in every way, but it is good enough for most users. In addition, there are not many alternative packages that are worth using.Phoronix can use more than 100 different test suites (that is, a set of group individual tests) and more than 450 different test profiles. You can choose to install only the part that you need, so if you only focus on processor and normal hard drive benchmarks, install "processor_tests" and "disk_tests". It also supports system
from a CD, DVD or USB drive, so you can test any machine's hardware when you need to use a "clean" operating system.2, Stress-ngYou might guess from the name that Stress-ng is a real stress test-it's great for testing the limits of a system, but because it's demanding, we don't recommend running it often. If the stress test is repeated, some parts, especially the processor and the ordinary hard drive, can be consumed faster. Install Stress-ng on Debi

Appearance mode is a common software design mode in software engineering. It provides a unified high-level interface for a group of interfaces in the subsystem. Subsystems are easier to use.
It is a State-mode UML diagram.
Structure
Facade
This appearance class provides a common external interface for packages 1, 2, and 3 in the subsystem.
Clients
A customer object reads and writes data resources of each interface in the subsystem through an external interface.
