Citrix Systems 6 manual GPU Commands, Event-wait

Class name

Description

pbd

The physical block devices through which hosts access SRs

event-wait

event-waitclass=<class_name> [<param-name>=<param_value>][<param-name>=/=<param_value>]

Blocks other commands from executing until an object exists that satisfies the conditions given on the command line. x=y means "wait for field x to take value y", and x=/=y means "wait for field x to take any value other than y".

Example: wait for a specific VM to be running.

xe event-wait class=vm name-label=myvm power-state=running

Blocks other commands until a VM called myvm is in the power-state"running."

Example: wait for a specific VM to reboot:

xe event-wait class=vm uuid=$VM start-time=/=$(xe vm-list uuid=$VM params=start-time --minimal)

Blocks other commands until a VM with UUID $VM reboots (i.e. has a different start-timevalue).

The class name can be any of the event classes listed at the beginning of this section, and the parameters can be any of those listed in the CLI command class-param-list.

GPU Commands

Commands for working with physical GPUs, GPU groups and virtual GPUs.

The GPU objects can be listed with the standard object listing commands (xe pgpu-list, xe gpu-group-list, and xe vgpu-list), and the parameters manipulated with the standard parameter commands. For details, see the section called “Low-level Parameter Commands”.

Physical GPU (pGPU) Parameters pGPUs have the following parameters:

Parameter Name	Description				Type
uuid	The	unique	identifier/object		Read only
	reference for the pGPU
vendor-name	The vendor name of the pGPU				Read only
device-name	The name assigned by the				Read only
	vendor to this pGPU model
gpu-group-uuid	The	unique	identifier/object		Read only
	reference for the GPU group
	that this pGPU has been
	automatically		assigned	to by
	XenServer;		identical	pGPUs
	across hosts in a pool are
	grouped together
