KVM: selftests: Add option to run dirty_log_perf_test vCPUs in L2
Add an option to dirty_log_perf_test that configures the vCPUs to run in
L2 instead of L1. This makes it possible to benchmark the dirty logging
performance of nested virtualization, which is particularly interesting
because KVM must shadow L1's EPT/NPT tables.
For now this support only works on x86_64 CPUs with VMX. Otherwise
passing -n results in the test being skipped.
