https://www.youtube.com/watch?v=B6mr-eh04ZQ 10분쯤에 KVM for regular VMs 에 보면 NS에서 실행되는 기존 VM 과 Realm world에서 실행될 VM의 차이점 설명합니다.
guest private memory용과 NS와 share할 메모리를 구분한다는 것과 이 2가지 용도들의 메모리 영역들이 하나의 memslot에서 표현 된다고 하는데요.
이 guest private memory 지원을 위해 qemu hva space에서 메모리를 할당받아 vm memory space에 매핑하지 않고, 별도의 memory-backed file을 만들어서 진행하려나 봅니다.

관련된 패치인데 머지되기전 주고 받은 의견들로 realm vm image 로딩에 관련된 부분도 엿볼 수 있습니다.
