The following makes 'x86info -r' dump kvm cpu ids (signature+features) when running in a vm.
On the guest we see the signature and the features: eax in: 0x40000000, eax = 00000000 ebx = 4b4d564b ecx = 564b4d56 edx = 0000004d eax in: 0x40000001, eax = 0100007b ebx = 00000000 ecx = 00000000 edx = 00000000 On the host it just adds a couple of zero lines: eax in: 0x40000000, eax = 00000000 ebx = 00000000 ecx = 00000000 edx = 00000000 eax in: 0x40000001, eax = 00000000 ebx = 00000000 ecx = 00000000 edx = 00000000 Signed-off-by: Michael S.
