Hotplug is user-controllable, so if the user refrains from adding pci devices after assigning a device to the guest, it should work. I think that USB interrupts are assigned to the controller, not the device, so USB hotplug can be ruled out. I admit this is fairly weak. >> implement it.

And msi makes sense technically as well. -- Do not meddle in the internals of kernels, for they are subtle and quick to panic. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
