Command line interface Parameter Name Description You can tune a VCPU's pinning with Type xe vm-param-set uuid= VCPUs-params:mask=1,2,3 A VM created from this template will then run on physical CPUs 1, 2, and 3 only. You can also tune the VCPU priority (xen scheduling) with the cap and weight parameters; for example xe vm-param-set uuid= VCPUs-params:weight=512 xe vm-param-set uuid= VCPUs-params:cap=100 VCPUs-max VCPUs-at-startup actions-after-crash console-uuids platform allowed-operations current-operations allowed-VBD-devices A VM based on this template with a weight of 512 will get twice as much CPU as a domain with a weight of 256 on a contended XenServer Host. Legal weights range from 1 to 65535 and the default is 256. The cap optionally fixes the maximum amount of CPU a VM based on this template will be able to consume, even if the XenServer Host has idle CPU cycles. The cap is expressed in percentage of one physical CPU: 100 is 1 physical CPU, 50 is half a CPU, 400 is 4 CPUs, etc. The default, 0, means there is no upper cap.
