Table 28 Dynamic Memory Characteristics
DescriptionSettingCharacteristic
No dynamic memory supportnoneType
Dynamic memory is configured on the host, but the dynamic
memory subsystem on the guest has not started and reported
the implementation type.
any
Dynamic memory is implemented in a driver and does not use
Guest OS Online Add/Delete features.
driver
Dynamic memory is implemented using Guest OS Online
Add/Delete features.
OLAD
The lower bounds for ram_target and
ram_dyn_target_start.
valueM (for
megabytes) or
valueG (for
gigabytes)
Minimum memory
The target memory size of the guest, set using ram_target or
ram_dyn_target_start.
valueM (for
megabytes) or
valueG (for
gigabytes)
Target memory
The upper bounds for ram_target and
ram_dyn_target_start.
valueM (for
megabytes) or
valueG (for
gigabytes)
Maximum memory
The current memory size of the guest (normally equal to target
memory).
valueM (for
megabytes) or
valueG (for
gigabytes)
Current memory
A value for ram_target which can be used to reduce the
guest memory but allow it sufficient memory resources to
continue running a minimal workload.
valueM (for
megabytes) or
valueG (for
gigabytes)
Comfortable minimum
Size of physical memory in the virtual machine presented to the
guest OS.
valueM (for
megabytes) or
valueG (for
gigabytes)
Boot memory
Amount of free memory in the guest.valueM (for
megabytes) or
valueG (for
gigabytes)
Free memory
Amount of memory in the guest allocated by user processes but
not locked. This memory is available for paging.
valueM (for
megabytes) or
valueG (for
gigabytes)
Available memory
A value between 0 and 100 used as an indicator of memory
deficit and paging. The higher the number the longer the system
has been in a memory deficit. A memory pressure value
approaching 100 usually means the system is hung.
valueMemory pressure
The allocation chunk size used by dynamic memory when
increasing and descreasing guest memory (as described in
Section 11.9.3.4 (page 186).
