xe vm-param-get uuid=

<uuid>

 param-name=memory-static-{min,max}

For example, the following displays the static maximum memory properties for the VM with the uuid beginning
ec77:

xe vm-param-get uuid= \ 

  ec77a893-bff2-aa5c-7ef2-9c3acf0f83c0 \ 

  param-name=memory-static-max;

  268435456

This shows that the static maximum memory for this VM is 268435456 bytes (256MB).

To  display  the  dynamic  memory  properties,  follow  the  procedure  as  above  but  use  the  command  param-
name=memory-dynamic:

1. Find the uuid of the required VM:

xe vm-list

2. Note the uuid, and then run the command param-name=memory-dynamic:

xe vm-param-get uuid=

<uuid>

 param-name=memory-dynamic-{min,max}

For example, the following displays the dynamic maximum memory properties for the VM with uuid beginning
ec77

xe vm-param-get uuid= \

  ec77a893-bff2-aa5c-7ef2-9c3acf0f83c0 \

  param-name=memory-dynamic-max;

  134217728

This shows that the dynamic maximum memory for this VM is 134217728 bytes (128MB).

It is essential that you use the correct ordering when setting the static/dynamic minimum/
maximum parameters. In addition you must not invalidate the following constraint:

0 

≤

 memory-static-min 

≤

 memory-dynamic-min 

≤

 memory-dynamic-max

≤

 memory-static-max

Update the static memory range of a virtual machine:

xe vm-memory-static-range-set uuid=

<uuid>

 min=

<value>

max=

<value>

Update the dynamic memory range of a virtual machine:

xe vm-memory-dynamic-range-set \

  uuid=

<uuid>

 min=

<value>

 \

  max=

<value>

Specifying a target is particularly useful in virtual server environments, and in any situation where you know
exactly how much memory you want a guest to use. XenServer will adjust the guest's memory allocation to meet
the target you specify. For example:

xe vm-target-set target=

<value>

 vm=

<vm-name>

 

Update all memory limits (static and dynamic) of a virtual machine:
