A physical host includes a memory, a first buffer, a second buffer, a third buffer and a processor. The first buffer stores a log regarding dirty pages. The second buffer stores a dirty bitmap, where the dirty bitmap is written into the second buffer according to the log read from the first buffer. The third buffer stores the dirty bitmap. The processor obtains the current memory address to be migrated and a destination memory address, and marks a page table corresponding to the memory address to be migrated as dirty pages and writes the log marked as the dirty pages into the first buffer when the memory address to be migrated is written. The processor includes a memory copy engine for reading the dirty bitmap from the third buffer, and copying the content corresponding to the dirty pages to the destination memory according to the dirty bitmap.

Physical host optimizing memory migration, operation method of physical host, and computer-readable storage medium thereof

Described herein is a method for optimizing a scalable GPU virtualization, comprising: providing each vGPU with a private shadow graphics translation table (GTT); copying vGPU's private shadow GTT to physical GTT along with the context switch, wherein the private shadow GTT allows vGPUs to share an overlapped range of a global graphics memory space.
