Citrix Systems 5.6 manual Restoring a VM to its previous state, Deleting a snapshot

For example, specifying power-state=haltedwill select all VMs whose power-state field is equal to 'halted'. Where multiple VMs are matching, the option --multiplemust be specified to perform the operation. The full list of fields that can be matched can be obtained by the command xe vm-list params=all.

Locate the required VM and then enter the following:

xe snapshot-list snapshot-of=<vm uuid>

For example:

xe snapshot-list snapshot-of=2d1d9a08-e479-2f0a-69e7-24a0e062dd35

This lists the snapshots currently on that VM:

uuid ( RO): d7eefb03-39bc-80f8-8d73-2ca1bab7dcff

name-label ( RW): Regular name-description ( RW):

snapshot_of ( RO): 2d1d9a08-e479-2f0a-69e7-24a0e062dd35

Restoring a VM to its previous state

Ensure that you have the uuid of the snapshot that you want to revert to, and then run the snapshot-revertcommand:

To do this:

1.Run the snapshot-listcommand to find the UUID of the snapshot or checkpoint that you want to revert to:

xe snapshot-list

2.Note the uuid of the snapshot, and then run the following command to revert:

xe snapshot-revert snapshot-uuid=<snapshot uuid>

For example:

xe snapshot-revert snapshot-uuid=b3c0f369-59a1-dd16-ecd4-a1211df29886

After reverting to a checkpoint, the VM will be suspended.

Note:

It is possible to revert to any snapshot in time,forwards or backwards. Existing snapshots and checkpoints are not deleted during revert.
