Citrix Systems 6 manual Vcpu-hotplug command

Parameter Name	Description						Type
VCPUs-number	the number of virtual CPUs						read only
	assigned to the VM
	For	a	paravirtualized		Linux
	VM, this number can differ
	from VCPUS-maxand can
	be changed without rebooting
	the	VM using		the		vm-
	vcpu-hotplug command.					See
	the section called “vm-vcpu-
	hotplug”. Windows VMs always
	run with the number of vCPUs
	set to VCPUs-maxand must be
	rebooted to change this value.
	Note that performance will drop
	sharply if you set VCPUs-
	number to a value greater than
	the number of physical CPUs on
	the XenServer host.
VCPUs-Utilization	a list of virtual CPUs and their						read only map parameter
	weight
os-version	the version of the operating						read only map parameter
	system for the VM
PV-drivers-version	the	versions		of		the	read only map parameter
	paravirtualized drivers				for	the
	VM
PV-drivers-up-to-date	flag for latest version of the						read only
	paravirtualized drivers				for	the
	VM
memory	memory		metrics	reported		by	read only map parameter
	the agent on the VM
disks	disk metrics reported by the						read only map parameter
	agent on the VM
networks	network		metrics	reported		by	read only map parameter
	the agent on the VM
other	other metrics reported by the						read only map parameter
	agent on the VM
guest-metrics-last-updated	timestamp when the last write						read only
	to these fields was performed
	by the in-guest agent, in the
	form	yyyymmddThh:mm:ss
	z, where z is the single-letter
	military timezone indicator, for
	example, Z for UTC (GMT)
