Hi,
We (kernel validation team) at Linaro running KVM unit tests [1] on arm64 and x86_64 architectures. Please share the Kernel configs fragments required for better testing coverage. Thank you.

For arm64 if you're testing on a host with a latest kernel installed, which of course has KVM enabled, and all the kvm-unit-tests test are passing (except for the GIC tests that are not appropriate for your host, which will be skipped), then you're getting all the coverage those tests provide.
I'm not sure about x86_64, but I imagine a similar statement to what I said for arm64 applies. If you don't get all passes, then you can check your host's config to see if there are KVM* symbols disabled that look relevant.

For x86 there's just CONFIG_KVM_INTEL and CONFIG_KVM_AMD.

As per your suggestions I have to enabled KVM configs. Which auto enabled below list of configs. With these config changes the number of test pass increased from 23 to 45.
PASS 45 FAIL 1 SKIP 10 Total 56
FAILED: -------------- vmware_backdoors
SKIPPED: -------------- pku svm taskswitch taskswitch2 ept vmx_eoi_bitmap_ioapic_scan vmx_hlt_with_rvi_test vmx_apicv_test hyperv_connections pmu

Thanks for great help.

For this to pass, please add module parameter kvm.enable_vmware_backdoor=1.
You should also add kvm.force_emulation_prefix=1.
Without the options you have now chosen, you were probably testing QEMU's x86 emulation rather than KVM.
