The ACRN hypervisor supports a logical partition scenario in which the User

OS (such as Clear Linux) running in a pre-launched VM can bypass the ACRN

OS (such as Ubuntu OS) running in a pre-launched VM can bypass the ACRN

guidelines provide step-by-step instructions on how to set up the ACRN

hypervisor logical partition scenario on Intel NUC while running two
