Take A Snapshot<\/strong><\/p>\n

 To list a kvm vm on Linux based server [VM ID]<\/strong>, more info<\/a><\/p>\n

virsh list  <\/code><\/strong><\/p>\n

If your KVM guests are now running with Qcow2 disk images, you can take an internal snapshot of the guest with the following command:<\/p>\n

virsh snapshot-create [VM ID]  <\/code><\/strong><\/p>\n

Alternatively, you can create a file with the following contents<\/p>\n

<domainsnapshot>
    <name>Name for the snapshot<\/name>
    <description>Description for the snapshot<\/description>
<\/domainsnapshot><\/code><\/em><\/p>\n

Then pass it to the snapshotting command.<\/p>\n

virsh snapshot-create [VM ID] [filepath]  <\/code><\/strong><\/p>\n

You can take snapshots of guests whilst they are running. Whilst the snapshot is being taken, the guest will be "paused". The "state" of the guest is also saved.<\/p>\n

List Snapshots<\/strong>
One can list a virtual machine's snapshots with<\/p>\n

sudo virsh snapshot-list [VM ID]  <\/strong><\/code><\/p>\n

Which will output something like:<\/p>\n

 Name                 Creation Time             State

Restore Snapshot<\/strong><\/p>\n

If you want to "revert", "go to", or "restore" a previous snapshot, then execute the following command:<\/p>\n

virsh snapshot-revert [VM ID] [Snapshot Name]  <\/code><\/strong><\/p>\n

Delete Snapshot<\/strong><\/p>\n

virsh snapshot-delete [VM ID] [Snapshot Name]  <\/strong><\/code><\/p>\n
