Description
Nested Virtualization Technology Performance Tuning
The performance of nested virtualization, a feature first introduced as a
preview in the v2.5 release, was improved. CPU and I/O performance of level 2
virtual machines (for example, a VM running on a KVM/QEMU VM that itself is a
VM on ACRN hypervisor) is now on par with a VM running on KVM on bare metal.

Format). This adds flexibility to OSs such as Zephyr running in pre-launched
VMs.
