KVM Guest support (including kvmclock) found in arch/x86/Kconfig

The configuration item CONFIG_KVM_GUEST:

• prompt: KVM Guest support (including kvmclock)
• type: bool
• depends on: CONFIG_PARAVIRT
• defined in arch/x86/Kconfig
• found in Linux kernels: 3.7–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.12

Help text

This option enables various optimizations for running under the KVM hypervisor. It includes a paravirtualized clock, so that instead of relying on a PIT (or probably other) emulation by the underlying device model, the host provides the guest with timing infrastructure such as time of day, and system time

KVM Guest support found in arch/powerpc/platforms/Kconfig
