Citrix Systems 5.6 manual Uuid=vmuuid

Parameter Name

Description

Type

VCPUs-params	configuration parameters for	read/write map parameter
	the selected VCPU policy.
	You can tune a VCPU's
	pinning with
	xe vm-param-set \
	uuid=<vm_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=<vm_uuid> \
	VCPUs-params:weight=512
	xe vm-param-set \
	uuid=<vm_uuid> \
	VCPUs-params:cap=100
	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.
VCPUs-max	maximum number of VCPUs	read/write
VCPUs-at-startup	boot number of VCPUs	read/write
