-Note that currently VFIO migration is supported only for a single device. This
-is due to VFIO migration's lack of P2P support. However, P2P support is planned
-to be added later on.
+To support migration of multiple devices that might do P2P transactions between
+themselves, VFIO migration uAPI defines an intermediate P2P quiescent state.
+While in the P2P quiescent state, P2P DMA transactions cannot be initiated by
+the device, but the device can respond to incoming ones. Additionally, all
+outstanding P2P transactions are guaranteed to have been completed by the time
+the device enters this state.
+
+All the devices that support P2P migration are first transitioned to the P2P
+quiescent state and only then are they stopped or started. This makes migration
+safe P2P-wise, since starting and stopping the devices is not done atomically
+for all the devices together.
+
+Thus, multiple VFIO devices migration is allowed only if all the devices
+support P2P migration. Single VFIO device migration is allowed regardless of
+P2P migration support.
 
 A detailed description of the UAPI for VFIO device migration can be found in

 Flow of state changes during Live migration
 ===========================================
 
-Below is the flow of state change during live migration.
+Below is the state change flow during live migration for a VFIO device that
+supports both precopy and P2P migration. The flow for devices that don't
+support it is similar, except that the relevant states for precopy and P2P are
+skipped.
 The values in the parentheses represent the VM state, the migration state, and
 the VFIO device state, respectively.
-The text in the square brackets represents the flow if the VFIO device supports
