[kvm-unit-tests PATCH] x86: hyperv_synic: Hyper-V SynIC test
Hyper-V SynIC is a Hyper-V synthetic interrupt controller.
The test runs on every vCPU and performs the following steps:
* read from all Hyper-V SynIC MSR's
* setup Hyper-V SynIC evt/msg pages
* setup SINT's routing
* inject SINT's into destination vCPU by 'hyperv-synic-test-device'
* wait for SINT's isr's completion
* clear Hyper-V SynIC evt/msg pages and destroy

[kvm-unit-tests PATCH] x86: hyperv_synic: Hyper-V SynIC test
...The solution is to have userspace enable KVM_CAP_HYPERV_SYNIC through
KVM_ENABLE_CAP, and modify vmx.c to not use apicv on VMs that have it
enabled. This requires some changes to the callbacks that only work if
enable_apicv or !enable_apicv:
if (enable_apicv)
kvm_x86_ops->update_cr8_intercept = NULL;
else {
kvm_x86_ops->hwapic_irr_update = NULL;
kvm_x86_ops->hwapic_isr_update = NULL;
kvm_x86_ops->deliver_posted_interrupt = NULL;
kvm_x86_ops->sync_pir_to_irr = vmx_sync_pir_to_irr_dummy;

[PATCH v9 00/84] VM introspection
The KVM introspection subsystem provides a facility for applications
running on the host or in a separate VM, to control the execution of
other VMs (pause, resume, shutdown), query the state of the vCPUs (GPRs,
MSRs etc.), alter the page access bits in the shadow page tables (only
for the hardware backed ones, eg. Intel's EPT) and receive notifications
when events of interest have taken place
