+Paravirtualized KVM features
+============================
+
+Description
+-----------
+
+In some cases when implementing hardware interfaces in software is slow, ``KVM``
+implements its own paravirtualized interfaces.
+
+Setup
+-----
+
+Paravirtualized ``KVM`` features are represented as CPU flags. The following
+features are enabled by default for any CPU model when ``KVM`` acceleration is
+enabled:
+
+- ``kvmclock``
+- ``kvm-nopiodelay``
+- ``kvm-asyncpf``
+- ``kvm-steal-time``
+- ``kvm-pv-eoi``
+- ``kvmclock-stable-bit``
+
+``kvm-msi-ext-dest-id`` feature is enabled by default in x2apic mode with split
+irqchip (e.g. "-machine ...,kernel-irqchip=split -cpu ...,x2apic").
+
+Note: when CPU model ``host`` is used, QEMU passes through all supported
+paravirtualized ``KVM`` features to the guest.
+
+Existing features
+-----------------
+
+``kvmclock``
+  Expose a ``KVM`` specific paravirtualized clocksource to the guest. Supported
+  since Linux v2.6.26.
+
+``kvm-nopiodelay``
+  The guest doesn't need to perform delays on PIO operations. Supported since
+  Linux v2.6.26.
+
+``kvm-mmu``
+  This feature is deprecated.
+
+``kvm-asyncpf``
+  Enable asynchronous page fault mechanism. Supported since Linux v2.6.38.
+  Note: since Linux v5.10 the feature is deprecated and not enabled by ``KVM``.
+  Use ``kvm-asyncpf-int`` instead.
+
+``kvm-steal-time``
+  Enable stolen (when guest vCPU is not running) time accounting. Supported
+  since Linux v3.1.
+
+``kvm-pv-eoi``
+  Enable paravirtualized end-of-interrupt signaling. Supported since Linux
+  v3.10.
+
+``kvm-pv-unhalt``
+  Enable paravirtualized spinlocks support. Supported since Linux v3.12.
+
+``kvm-pv-tlb-flush``
+  Enable paravirtualized TLB flush mechanism. Supported since Linux v4.16.
+
+``kvm-pv-ipi``
+  Enable paravirtualized IPI mechanism. Supported since Linux v4.19.
+
+``kvm-poll-control``
+  Enable host-side polling on HLT control from the guest. Supported since Linux
+  v5.10.
+
+``kvm-pv-sched-yield``
+  Enable paravirtualized sched yield feature. Supported since Linux v5.10.
+
+``kvm-asyncpf-int``
+  Enable interrupt based asynchronous page fault mechanism. Supported since Linux
+  v5.10.
+
+``kvm-msi-ext-dest-id``
+  Support 'Extended Destination ID' for external interrupts. The feature allows
+  to use up to 32768 CPUs without IRQ remapping (but other limits may apply making
+  the number of supported vCPUs for a given configuration lower). Supported since
+  Linux v5.10.
+
+``kvmclock-stable-bit``
+  Tell the guest that guest visible TSC value can be fully trusted for kvmclock
+  computations and no warps are expected. Supported since Linux v2.6.35.
+
+Supplementary features
+----------------------
+
+``kvm-pv-enforce-cpuid``
+  Limit the supported paravirtualized feature set to the exposed features only.
+  Note, by default, ``KVM`` allows the guest to use all currently supported
+  paravirtualized features even when they were not announced in guest visible
+  CPUIDs. Supported since Linux v5.10.
+
+
+Useful links
+------------
+
+Please refer to Documentation/virt/kvm in Linux for additional details.
