Guest Memory

The Guest Memory statistics allow to determine how much memory the Hypervisor is managing and using on behalf of a VM.

They indicate in the “1G GPA Pages” and “2M GPA Pages” counters whether or not a VM is using large pages which improves overall VM performance. Large pages are only used on systems that have vTLB hardware support. The “Deposited Pages” counter indicates how much memory the hypervisor is using for managing the VM.

GPA Pages

1G The number of 1G pages present in the GPA space of the partition.
2M The number of 2M pages present in the GPA space of the partition.
4K The number of 4K pages present in the GPA space of the partition.
DP The number of pages deposited into the partition.

Memory used by Hypervisor for managing VM (MBytes)

GPA Figures out most of the memory used for the VM in Megabytes :

Formula: total_vm_memory = “1G GPA Pages” * 1024 + (“2M GPA Pages” * 2) + ((“4K GPA Pages” + “Deposited pages”) / 256).
