A company runs a mix of VMs on KVM hosts. Some VMs require near-native performance for CPU-intensive workloads, while others run legacy operating systems that do not support hardware virtualization extensions. The admin needs to ensure all VMs can run. Which approach should the admin take?

Use KVM for legacy VMs and QEMU for modern VMs.

Use QEMU in software emulation for all VMs to ensure compatibility.

Use KVM for VMs that support hardware virtualization and QEMU in software emulation mode for legacy VMs.

Use KVM for all VMs, as it can emulate CPUs without hardware extensions.
