While it is possible to run the examples in this chapter on an older system, we recommend using a more modern system that has hardware support for virtualization. This will ensure higher performance during the exercises, as full emulation can severely hamper the progress, especially on older systems.

To verify whether your system has hardware support for virtualization (and can therefore use the Linux KVM-based virtualization), the following command should have output:

# grep -E 'svm|vmx' /proc/cpuinfo
flags   : fpu vme de ... vmx ...

If no output is shown, then the system does not support hardware-assisted virtualization.
