It is important to note there is a correlation between all the parameters Memory limits must satisfy: static_min ≤ dynamic_min = dynamic_max = static_max To modify the memory configuration for a Virtual machine in XEN through the cli commands you will have to stop the server # xe vm-shutdown name-label="machine name" Review the current memory configuration with # xe vm-list params=all name-label="machine name" | grep memory you have to find the uuid of the machine, that can be showed Read more...
