Message

Hi,

This series aims to improve user experience by providing
a better error message when the user tries to enable KVM
on machines not supporting it.

Since v1:
- added missing x86 arch (Peter)
- consider all accelerators (Daniel and Peter)
- do not enable KVM on sbsa-ref (Leif)
- updated 'query-machines' (Daniel)
- new patch for XenPV

Supersedes: <[e-mail]>

Philippe Mathieu-Daudé (11):
  accel/kvm: Check MachineClass kvm_type() return value
  hw/boards: Introduce machine_class_valid_for_accelerator()
  hw/core: Restrict 'query-machines' to those supported by current accel
  hw/arm: Restrit KVM to the virt & versal machines
  hw/mips: Restrict KVM to the malta & virt machines
  hw/ppc: Restrict KVM to various PPC machines
  hw/s390x: Explicit the s390-ccw-virtio machines support TCG and KVM
  hw/i386: Explicit x86 machines support all current accelerators
  hw/xenpv: Restrict Xen Para-virtualized machine to Xen accelerator
  hw/board: Only allow TCG accelerator by default
  softmmu/vl: Exit gracefully when accelerator is not supported
