Hi, all
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 provide 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.
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.
