[Qemu-devel] [PATCH 28/35] kvm: Consider EXIT_DEBUG unknown without CAP_SET_GUEST_DEBUG

[Marcelo Tosatti]

From: Jan Kiszka <address@hidden>

Without KVM_CAP_SET_GUEST_DEBUG, we neither motivate the kernel to
report KVM_EXIT_DEBUG nor do we expect such exits. So fall through to
the arch code which will simply report an unknown exit reason.
