Lists CDs attached to the specified VMs.

The VM or VMs on which this operation should be performed are selected via the standard selection mech-

anism (see VM selectors). Optional arguments can be any number of the VM parameters listed at the be-

ginning of this section.

You can also select which VBD and VDI parameters to list.

vm-cd-remove cd-name=name of cd [ vm-selector=vm selector value...]

Remove a virtual CD from the specified VMs.

The VM or VMs on which this operation should be performed are selected via the standard selection mech-

anism (see VM selectors). Optional arguments can be any number of the VM parameters listed at the be-

ginning of this section.

5.4.22.6. vm-clone

vm-clone new-name-label=name for clone [new-name-description=description for clone ] [

vm-selector=vm selector value...]

Clone an existing VM, using storage-level fast disk clone operation where available. Specify the name

and the optional description for the resulting cloned VM using the new-name-label and new-name-

The VM or VMs on which this operation should be performed are selected via the standard selection mech-

anism (see VM selectors). Optional arguments can be any number of the VM parameters listed at the be-

ginning of this section.

5.4.22.7. vm-compute-maximum-memory

vm-compute-maximum-memory total=amount of available physical RAM in bytes

[approximate=add overhead memory for additional vCPUS? true | false ] [ vm-selector=vm

selector value...]

Calculate the maximum amount of static memory which can be allocated to an existing VM, using the total

amount of physical RAM as an upper bound. The optional parameter approximate reserves sufficient

extra memory in the calculation to account for adding extra vCPUs into the VM at a later date.

For example:

xe vm-compute-maximum-memory vm=testvm total=`xe host-list params=memory-free

--minimal`

uses the value of the memory-free parameter returned by the xe host-list command to set the maximum

memory of the VM named "testvm."

The VM or VMs on which this operation will be performed are selected via the standard selection mechanism

(see VM selectors). Optional arguments can be any number of the VM parameters listed at the beginning

of this section.

5.4.22.8. vm-copy

vm-copy new-name-label=name for copy [new-name-description=description for copy ] [ sr-

uuid=UUID of SR ] [ vm-selector=vm selector value...]
