[PATCH 0/2] avoid assertion failure when trying confidential guests without KVM

Posted by Paolo Bonzini 1 month, 1 week ago

When using confidential guests and forgetting the accelerator, the result
is not very nice:

    $ qemu-system-x86_64 -object sev-guest,id=sev0,policy=0x5,id=sev0,cbitpos=51,reduced-phys-bits=1 -M confidential-guest-support=sev0
    qemu-system-x86_64: ../softmmu/vl.c:2619: qemu_machine_creation_done: Assertion `machine->cgs->ready' failed.

Assume that the lack of initialization is due to missing code in the
accelerator to look at current_machine->cgs, and report a nicer
error error.

Paolo Bonzini (2):
  vl: convert qemu_machine_creation_done() to Error **
  vl: do not assert if sev-guest is used together with TCG
