Check whether the CPU supports Virtualization
I. Windows platform:
Use the small tool securable.

You need to check the Hardware Virtualization alization option. The first three cases are simple:
NO: CPU does not support
Yes: CPU support. Set the VT switch in BIOS to Enabled.
Locked ON: supported by CPU and enabled by BIOS
Locked OFF: the BIOS currently disables virtualization technology, but is not sure whether the CPU itself supports it. In this case, first check if there is Virtualization Technology in the BIOS and set it to Enabled, and then re-test. If the result does not change, it will still be useless.

Ii. Linux platform:
Run the cat/proc/cpuinfo command on the terminal and find the flags section. If VMX or SVM is output, virtualization technology is supported.
Cat/proc/cpuinfo | grep vmx # (for Intel CPU)
Or
Cat/proc/cpuinfo | grep svm # (for amd cpu)
