MemoryRegion *(*get_memory_region)(PCDIMMDevice *dimm); } PCDIMMDeviceClass; 每个PCDIMMDevice对象都与 HostMemoryBackend对象相关联。HostMemoryBackend也是使用QEMU中的面向对象编程模型QOM定义的。HostMemoryBackend定义在include/sysemu/hostmem.h中。HostMemoryBackend对象包含了客户机内存对应的真正的主机内存,这些...

pci_memory:给PCI设备分配的内存 rom_memory:主机在自己的虚拟内存上给虚拟机分配的物理内存,但是这块内存只可读不可写入 lowmem:因为一些有传统设备的虚拟机,其设备必须使用一些地址空间在4GB以下的内存,所以设置了这个变量,源代码中关于lowmem的注释如下
The "pc-dimm" and "memory-backend" objects are the user-visible parts of guest RAM in QEMU. They can be managed using the QEMU command-line and QMP monitor interface. This is just the tip of the iceberg though because there are still several aspects of guest RAM internal to QEMU that ...
