https://bugzilla.kernel.org/show_bug.cgi?id=77271 Alex Williamson <alex.williamson@xxxxxxxxxx> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |alex.williamson@xxxxxxxxxx --- Comment #1 from Alex Williamson <alex.williamson@xxxxxxxxxx> --- Further up in cpuid.txt is the statement: "This is not always guaranteed to work, since userspace can mask-out some, or even all KVM-related cpuid features before launching a guest." Which is exactly what is happening here. QEMU sets eax = 0 for this leaf: target-i386/kvm.c memcpy(signature, "KVMKVMKVM\0\0\0", 12); c = &cpuid_data.entries[cpuid_i++]; c->function = KVM_CPUID_SIGNATURE | kvm_base; c->eax = 0; c->ebx = signature[0]; c->ecx = signature[1]; c->edx = signature[2]; So I don't think there's a bug here. -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
