List the data sources that can be recorded for a VM.
The VM or VMs on which this operation should be performed are selected using the standard selection
mechanism (see VM selectors). Optional arguments can be any number of the VM parameters listed at the
beginning of this section.
vm-data-source-query
vm-data-source-query data-source=<name_description_of_data-source> [<vm-selector>=<vm
selector value>...]
Display the specified data source for a VM.
The VM or VMs on which this operation should be performed are selected using the standard selection
mechanism (see VM selectors). Optional arguments can be any number of the VM parameters listed at the
beginning of this section.
vm-data-source-record
vm-data-source-record data-source=<name_description_of_data-source> [<vm-selector>=<vm
selector value>...]
Record the specified data source for a VM.
This will write the information from the data source to the VM's persistent performance metrics database.
This database is distinct from the normal agent database for performance reasons.
Data sources have the true/false parameters standard and enabled, which can be seen in the output of
the vm-data-source-list command. If enabled=true, the data source metrics are currently being recorded
to the performance database; if enabled=false they are not. Data sources with standard=true have
enabled=true and have their metrics recorded to the performance database by default. Data sources
which have standard=false have enabled=false by default. The vm-data-source-record command
sets enabled=false.
Once enabled, you can stop recording the metrics of the data source by running the vm-data-source-forget
command.
The VM or VMs on which this operation should be performed are selected using the standard selection
mechanism (see VM selectors). Optional arguments can be any number of the VM parameters listed at the
beginning of this section.
vm-destroy
vm-destroy uuid=<uuid_of_vm>
Destroy the specified VM. This leaves the storage associated with the VM intact. To delete storage as well,
use xe vm-uninstall.
vm-disk-add
vm-disk-add disk-size=<size_of_disk_to_add> device=<uuid_of_device>
[<vm-selector>=<vm_selector_value>...]
Add a new disk to the specified VMs. Select the device parameter from the value of the allowed-VBD-
devices parameter of the VMs.
