You'd have to read ISR to check that the > interrupt was intended for your device. The virtio 0.9.5 spec says that ISR is "unused" when in MSI-X mode. I don't think that you can depend on the device to set the configuration changed bit. The virtio 1.0 spec seems to have fixed that. _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
