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

1 User Initiates an export of a running VM

2Hyper-V performs a live, point-in-time export of the VM, which remains running, creating the new files in the target location

3 Admin imports new, powered-off VM on the target host, finalizes configuration and starts VM

4 With Virtual Machine Manager, Admin can select host as part of the clone wizard
