+VTd device hotplug:
+-------------------
+
+2 virtual PCI slots (6~7) are reserved in HVM guest to support VTd hotplug. If
you have more VTd devices, only 2 of them can support hotplug. Usage is simple:
+
+ 1. List the VTd device by dom. You can see a VTd device 0:2:0.0 is inserted
in the HVM domain's PCI slot 6. '''lspci''' inside the guest should see the
same.
+
+ [root@vt-vtd ~]# xm pci-list HVMDomainVtd
+ VSlt domain bus slot func
+ 0x6 0x0 0x02 0x00 0x0
+
+ 2. Detach the device from the guest by the physical BDF. Then HVM guest will
receive a virtual PCI hot removal event to detach the physical device
+
+ [root@vt-vtd ~]# xm pci-detach HVMDomainVtd 0:2:0.0
+
+ 3. Attach a PCI device to the guest by the physical BDF and desired virtual
slot(optional). Following command would insert the physical device into guest's
virtual slot 7
+
+ [root@vt-vtd ~]# xm pci-attach HVMDomainVtd 0:2:0.0 7
+
+VTd hotplug usage model:
+------------------------
+
+ * For live migration: As you know, VTd device would break the live migration
as physical device can't be save/restored like virtual device. With hotplug,
live migration is back again. Just hot remove all the VTd devices before live
migration and hot add new VTd devices on target machine after live migration.
+
+ * VTd hotplug for device switch: VTd hotplug can be used to dynamically
switch physical device between different HVM guest without shutdown.
