[libvirt] USB: USB Passthrough Device Autoconnect Feature
Hello, Qemu upstream had achieved USB Passthrough Device Autoconnect Feature for the guest. Such as a USB device is unplugged from the host then plugged back in to the same USB physical port. the patch was: https://lists.gnu.org/archive/html/qemu-devel/2011-05/msg02341.html However, Libvirt has not provided such an interface that identifies a USB device for pass through with physical port, rather than the device number. Do you have any ideas or plans about this problem? Thanks in advance. Best Regards, -WangYufei -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list

Thanks in advance. Automatically connecting host devices as they are plugged into the host is a policy decision, and has security implications too - QEMU will be forbidden to access any plugged devices due to sVirt and also file permissions. As such we delegate this tasks to applications using libvirt, and do not intend to do anything to have this automatic plugging done by libvirt or qemu itself.
