Dynamic Memory | Smart Paging
Hyper-V Smart Paging
• Reliable way to keep a VM running when no physical memory is available
• Performance will be degraded as disk is much slower than memory
Used in the following situations:
• VM restart
• No physical memory is available
• No memory can be reclaimed from other virtual machines on that host
Utilize disk as additional, temporary memory
