* gnu/packages/bootloaders.scm (qemu-minimal-2.10): Remove variable.
* gnu/packages/virtualization.scm (qemu)[inputs]: Use sdl2 instead of sdl.
[native-inputs]: Use python-wrapper instead of python@2.
* gnu/packages/virtualization.scm (qemu-minimal)[inputs]: Remove sdl2 instead of
sdl from inherited packages.
* gnu/packages/virtualization.scm (qemu-minimal-2.10): Add variable.
[native-inputs]: Remove python-wrapper from inherited packages and use python@2
instead.
