12.04 LTS supports nested virtualization. If I use a 12.04 LTS kernel with kvm_intel nested=1 and boot a 12.04 LTS guest, I am able to load the kvm_intel kernel module in the guest. If I use the same host and boot a 12.10 guest, the kvm_intel module does not load:

$ sudo modprobe kvm_intel
FATAL: Error inserting kvm_intel (/lib/modules/3.5.0-6-generic/kernel/arch/x86/kvm/kvm-intel.ko): Input/output error

The kvm module loads fine in the guest. The guest is up to date 12.10 amd64. The host is up to date 12.04 LTS amd64.
