addressable by your operating system. Setting a memory maximum that is greater than the operating system

supported limit, may lead to stability problems within your guest.

xe CLI commands

Display the static memory properties of a VM

1. Find the uuid of the required VM:

xe vm-list

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

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).

Display the dynamic memory properties of a VM

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

name=memory-dynamic:
