Chapter 2. KVM compatibility

The KVM hypervisor requires a processor with the Intel-VT or AMD-V virtualization extensions.
Note that this list is not complete. Help us expand it by sending in a bug with anything you get working.
To verify whether your processor supports the virtualization extensions and for information on enabling the virtualization extensions if they are disabled, refer to Section 25.4, “Verifying virtualization extensions”.
The Fedora kvm package is limited to 256 processor cores.
