qemu-system-x86 binary package in Ubuntu Oracular riscv64

 QEMU is a fast processor emulator: currently the package supports
 i386 and x86-64 emulation. By using dynamic translation it achieves
 reasonable speed while being easy to port on new host CPUs.
 .
 This package provides the full system emulation binaries to emulate
 the following x86 hardware: i386 x86_64 (amd64).
 .
 In system emulation mode QEMU emulates a full system, including a processor
 and various peripherals. It enables easier testing and debugging of system
 code. It can also be used to provide virtual hosting of several virtual
 machines on a single server.
 .
 On x86 host hardware this package also enables KVM kernel virtual machine
 usage on systems which supports it.
