Binary package “qemu-system-gui” in ubuntu oracular

QEMU full system emulation binaries (graphical display and audio modules)

 This package provides optional graphical guest display modules (currently GTK
 and SDL) and audio backend modules for full system emulation (qemu-system-*)
 packages.
 .
 This package is not a management/control/GUI interface for qemu, use something
 else (like virt-manager) for that.
