 Disk-only File-based Storage Instance Snapshot on KVM

+Pause During Live Instance Snapshots on KVM
+-------------------------------------------
+
+When creating **Instance Snapshots with Memory**, CloudStack uses Libvirt’s
+*domain snapshot* API to create an Internal Snapshot that includes Memory.
+The guest’s memory state is written directly into the root volume’s QCOW2 file.
+This causes the instance to pause for the duration of the memory dump. The pause
+time is typically much longer than with VMware snapshots, but this is a limitation
+with Internal Snapshots in Libvirt.
+
+**Instance Snapshots without Memory** has seen significant improvements since Cloudstack 4.21 with the
+:ref:`Disk-only-File-based-Storage-Instance-Snapshots-on-KVM` feature for NFS and local storage.
+Pre 4.21, the Instance would be frozen for the entire duration of the snapshot create operation.
+Since 4.21, the Instance is only frozen during the checkpointing operation, which is significantly less.
+
+Users looking for the Instance Snapshot feature in KVM are recommended to use the
+:ref:`Disk-only-File-based-Storage-Instance-Snapshots-on-KVM` feature, if the pause duration is a concern.
+App consistent snapshots can be created by using the ``quiescevm`` parameter with pre and post-freeze hooks.
+The Instance should have Qemu Guest Agent installed for this to work.
