+ This listen type doesn't have any other attribute. Libvirt supports + passing a file descriptor through our APIs virDomainOpenGraphics() and + virDomainOpenGraphicsFD(). No other listen types are allowed if this + one is used and the graphics device doesn't listen anywhere. You need + to use one of the two APIs to pass a FD to QEMU in order to connect to + this graphics device. Supported by graphics type spice. +
