== Enabling nested virtualization in KVM
Nested virtualization allows you to run a virtual machine (VM) inside another VM while still using hardware acceleration from the host. == Checking if nested virtualization is supported
=== Checking if nested virtualization is supported
For Intel processors, check the `/sys/module/kvm_intel/parameters/nested` file. For AMD processors, check the `/sys/module/kvm_amd/parameters/nested` file. If you see `1` or `Y`, nested virtualization is supported; if you see `0` or `N`, nested virtualization is not supported. For Intel processors, check the `/sys/module/kvm_intel/parameters/nested` file. For AMD processors, check the `/sys/module/kvm_amd/parameters/nested` file. If you see `1` or `Y`, nested virtualization is supported; if you see `0` or `N`, nested virtualization is not supported.
