I'd give it a fail, tell it to go back and repeat the training course.

Re: Windows 11 VMs

2021-07-18 Thread Tom Horsley
In other Windows 11 VM news: I experimented with the mbr2gpt tool
in Windows 10 to see if it could really switch my KVM to UEFI.

The /validate option works fine. It says my disk is good to
convert, then the /convert option says:

Cannot perform layout conversion. Error: 0x0001

The %errorlevel% is 10 which means "I can't do it, waah!"
(or specifically "Conversion failed due to error while applying GPT layout.")

So I'll probably just give Windows 11 a pass :-).

Used the instructions here:

https://www.maketecheasier.com/convert-legacy-bios-uefi-windows10/

Also found I had to run

net user administrator /active:yes

before I could follow those instructions.

None of your hardware is automatically available. The virtual CPU may
not even be the same as the real one.


That's for sure.  My VM's think they have Intel i7 CPU's while my 
host system is actually

i5.
If I look at /proc/cpuinfo and it lists the 4 cpu's I've given to the 
vm as being the same name as the physical cpu and that it is an 8 
core cpu in the modelname section and in the vendorid section is says 
it is an AuthenticAMD, isn't that telling me the vm is seeing the 
physical cpu?


Not really.  It depends on the VM system, but at least for some, the 
default is to pass the real CPU's cpuid into the VM's "CPU". The 
virtual OS is running on the physical CPU (emulation is *SLOW*), but 
the bits that identify the CPU are special instructions.  These are 
intercepted by the VM and adjusted to give the answers you want.  I 
suspect that the actual extended instructions (like AVX, SSEx, or 
whatever) would still be usable even if the cpuid was adjusted to 
exclude them.
Found an interesting issue with virtualbox on a Windows 10 host. As the 
Windows 11 installer I have requires Windows 10 to already be installed, 
I installed Windows 10 in a virtualbox vm, and with the vm running in 
the default window mode Windows 11 complained it wasn't an environment 
where Windows 11 could be installed, but if I switched the vm into 
fullscreen mode Windows 11 installed quite happily.

Steve

There are different implementations of the TPM spec.  Both Intel and AMD
have CPU-based versions in more recent models; for AMD, this is called
fTPM.  It's also possible to have a discrete TPM module, which a bunch
of motherboards include a header for.

The rush to buy modules is uninformed; probably a lot of those systems
could just enable the CPU-based TPM in their BIOS.  I don't remember
when Intel added it (5 years ago?) and don't know if they added it for
all CPU models or just some.  I think AMD added their fTPM when they
introduced socket AM4 (almost 5 years ago).

I think the advantage of a discrete and socketed module would be that
you can take it with you; either literally (unplug it when you leave the
house for example) or just when you replace the motherboard.

Unless it's changed recently, the TPM isn't part of the CPU.  It's a 
separate chip on the motherboard or apparently you can get one on an 
add-on card for computers that don't have one.  Although I've heard 
that because of Windows 11, those cards have become expensive and hard 
to get.
I thought the TPM was in the cpu, because someone I work with was 
indicating it was in the cpu, and in my motherboard's bios the 
activation/deactivation of the fTPM is in the cpu configuration section.

I doubt that that will last long.  Once the early adopters have theirs, 
the demand will drop, and so will the price.

Unless it's changed recently, the TPM isn't part of the CPU.  It's a 
separate chip on the motherboard or apparently you can get one on an 
add-on card for computers that don't have one.  Although I've heard that 
because of Windows 11, those cards have become expensive and hard to get.

None of your hardware is automatically available. The virtual CPU may

That's for sure.  My VM's think they have Intel i7 CPU's while my host system 
is actually
i5.

I should apologize! I was thinking of this machine, which is almost new, and 
probably has the TPM in hardware. It's the laptop that's old, and has Windows

Smartcard readers are tricky beasts.
The type-2 and type-3 (pinpad-readers) are the worst.
I know Vasco distributes them through the banking-channels.

As stated earlier, my system doesn´t have a hardware TPM, but adding a

but it occurs to me that you might not be permitted to install the software

Quite probably it *is* a fault, nine times out of ten (which makes you
ignore the time it's really a problem).

With badly engineered hardware, software, and stupidly worded error
messages, the blame is really not on the user.

"Pragmatically speaking ..." ;-)  Seriously, I think TPM mostly makes
sense with VMs.  People who write programs are generally going to be
very unhappy with the amount of kissing up to the TPM they have to
do.
Like, on Mac every time LLVM releases a new version of the debugger I
have to go through the self-signing dance.  So far I have been
satisfied with the results every time (there really are new features
or performance improvements), but it's infrequent enough that I have
no memory of the procedure, let alone muscle memory.

Indeed. I have no particular interest in TPM as such. My original
question was aimed at anticipating possible issues with VMs and Windows
11 if I ever get round to installing it, but that seems to be resolved.



Yes, I installed Windows 11 in a VM just fine with an emulated TPM. I don't 
actually use
Windows all that much.  But, for what I use it Windows 11 does seem to do it 
better.
I only use it mainly for the WebATM of the Taiwan Post Office Bank. In Windows 
10 I had to get the
sequence just right for plugging in the USB smart card reader and inserting my 
bank
card.

Still sucks that the Post Office doesn't support Linux.  :-(

Sorry, I thought the "TPM Manufacturer Section" of the TPM output was 
indicating there was a TPM when it indicated the version.

Maybe I don't actually have the hardware.

Oh, I'd never noticed.  It is in virt-manager "add hardware"
section.

You're right. Even better.

Just tried it using the default settings and it worked. After
booting
Windows 10, type 'tpm' into a Windows Shell (admin) instance and it
confirms the module exists.

Interesting, the windows command you have listed indicates that I
have
an AMD V2.0 tpm, which I assume is in the ryzen cpu, but Fedora via
journalctl | grep -i tpm tells me a tpm doesn't exist.

Is this directly on the hardware or in a VM? If the former, it would
appear to be a bug. If the latter, presumably the VM is emulating the
TPM.
Windows is Windows 10 and it is native, I boot the machine into Windows 
10. Fedora is running inside a Vmware Player Vm hosted on the Windows 10 
machine the screenshot is from.
From the screenshot in the attachment I assume it is telling me that 
under Windows 10 it is finding a tpm, is that correct?

Indeed.  Pragmatically speaking, I don't think they're wrong, do you?

"Pragmatically speaking ..." ;-)  Seriously, I think TPM mostly makes
sense with VMs.  People who write programs are generally going to be
very unhappy with the amount of kissing up to the TPM they have to do.
Like, on Mac every time LLVM releases a new version of the debugger I
have to go through the self-signing dance.  So far I have been
satisfied with the results every time (there really are new features
or performance improvements), but it's infrequent enough that I have
no memory of the procedure, let alone muscle memory.

Yeah, there was a *lot* of angst about potential DRM applications at
the time.  I'm willing to bet it's possible to distinguish a hardware
TPM from a software TPM for that application, though.  I didn't look
hard enough to see if the Xen folk had proposed a protocol to get a
token from the hardware TPM to vouch for a VM in that case.

I think much depends on what the TPM is used for. Certainly if the user
takes care not to subvert the intention, it can reasonably be used to
ensure that only trusted software is run. OTOH, I think one application
of TPM (at least when originally proposed) was to prevent the user from
bypassing DRM, in which case the trust goes in the other direction and
the situation is different.

My only Win10 VM was BIOS.

So, I had to create a new VM using UEFI.

resolution.
I subsequently found out that I needed to download the Latest virtio-win ISO

https://github.com/virtio-win/virtio-win-pkg-scripts/blob/master/README.md
and run the script contained within.

Other than that, it is all working as it should.



And I just installed a Windows 11 system in the same way.  All's good.

I reckon the default thought of most people who're suddenly faced with
a computer failing a security test is not going to be that something
has changed on them without authority, but that something has gone
wrong.  They're going to try and reset something, rather than work out
if they've been compromised.

That depends on the implementation of the virtual TPM.  Although from
what I'm reading it shouldn't transparently virtualize the hardware
TPM (if present), the hardware TPM can be used to provide a trust root
for the virtual TPM, which can then attest to the VM.  I would assume
that to really trust any system, you'd need to have out-of-band
knowledge of the TPM's identity, whether hardware or software.  It's
true that there's more room for malware to wedge itself in in this

As for "false sense of security", that has been a Microsoft business
model at least since they trumpeted "Orange Book Level C" security
(the highest you can get without physically securing the device) for
Windows NT in the 1990s -- which certification was invalid if you

Software TPMs are software emulators of TPMs that run with no more

depend entirely on the environment that they run in, so they provide no

In the case of Windows 11 under a VM, as you say the software TPM can do

what it likes. In effect, there is no more guarantee than with a system
without a TPM and the message that Windows 11 can only be used where a TPM
provides a trust base might give a false sense of security.

Why?  If you're running it in a VM, you've made a conscious choice to 
use the emulated TPM.  What is ridiculous about that?  No matter what

Hi Poc,

Fedora 34
qemu-kvm-5.2.0-8.fc34.x86_64

I have Windows 11 Version Dev (OS Build 22000.1) running
under qemu-kvm.   I installed it from ISO on a blank VM.



may I ask where you got this ISO from?


CERTAINLY !

https://uupdump.net/


It downloads a zip file with a script inside. You
run the script for your OS.  The script will go
out to M$'s update site and creates an ISO for you.

If the script crashes (mine did three times), rerun
it and it will continue where it left off

It is a piece of hardware that either comes with your motherboard

Anything made in the last few years should have one.  If you're running 
Linux, you can check with "ls /dev/tpm*" or "journalctl | grep -i tpm".

Windows 11 VMs and TPM - an interesting side effect

2021-07-03 Thread Tom Horsley
Out of curiosity, I thought I'd see if a physical TPM module is
available for my motherboard. Looking in the manual I see there
is a header for one, and gigabyte has a specific model number
for the one that is compatible.

None are in stock anywhere save a couple of entries on ebay where
the normally $15 module is now listed at $170 :-).

A KVM emulated one is clearly the way to go.

Same here.

I've not installed a Windows machine in several years.  I wonder if things have 
changed since my
last install as I would have thought TPM hardware would have been added by 
default to the
hardware.

qemu has support for a TPM 2.0 either as a passthrough or an 
emulation.   I haven't tested it yet, but I assume it works.


I tested it and Windows 10 let me enable bitlocker, so it definitely 
accepts it. 



Are you sure, because enabling bitlocker is also possible without a TPM 
in Win10;


There's an option to use a flash drive instead, but that's not what I 
used.  I tried without the TPM added and it said no, then I added the 
TPM and it did it.

qemu has support for a TPM 2.0 either as a passthrough or an

I tested it and Windows 10 let me enable bitlocker, so it definitely
accepts it.


I have zero experience with TPM.  To utilize this do you need to make
use of

swtpm - TPM Emulator for TPM 1.2 and 2.0

no the qemu host?

Apparently not: https://en.opensuse.org/Software_TPM_Emulator_For_QEMU
(that's just the first one that popped up).


OK, so just following the instructions for libvirt and it will start it for you.

Just have to add the tpm device to your vm using virsh.

I'll have to give that a try.  My Win10 VM doesn't have that device.




Oh, I'd never noticed.  It is in virt-manager "add hardware" section.

Are you sure, because enabling bitlocker is also possible without a TPM

Nice. That would seem to make the whole underlying concept of a TPM
absurd, given that you can emulate it (unless that means it has
actually been signed by some authority of course).

haven't tested it yet, but I assume it works.


Now, if qemu could also emulate the more recent CPUs (that Win11 is rumored  
as being restricted to) on the older CPUs that Win11 won't support, then I  
can't decide whether that's going to be awesome, or funny. Or both, since  
I'm pretty sure that qemu can emulate it (so the awesome part is guaranteed,  
and the funny part is the only one that's in question).

I was hoping for something along the lines of a new OVMF release with
included TPM support. I'll give it time.
