The processor must support Hardware-Assisted Virtual Machine (HVM).
To check if the processor supports HVM use the following command:
For Intel processors:
grep -i vmx /proc/cpuinfo
For AMD processors:
grep -i svm /proc/cpuinfo
If nothing returns, then fully virtualization guests will not run.
In the BIOS verify virtualization is enabled:
To check if the BIOS is enabled, issue the following command:
grep -i hvm /sys/hypervisor/properties/capabilities
If nothing returns; reboot the system and enable the BIOS, look for the setting relating to virtualization, HVM, VT, VMX or SVM.
The BIOS may contains different names for the virtualization setting; check the hardware manual or contact the hardware vendor for more details.
