What is the best and less expensive Lenovo think pad for new Qube?
Altough its most likly not an option will all X1 Carbon work?
And this is the latest recomended vertion of qubes? Seams as if many models are out dated now.
A advantage with this modele aside from being portable. Is that a regular big SSD drive fits ib there.

I do have a few questions for anyone experienced with the x230
Q1: Does the ThinkPad x230 have a separate USB controller available for
use as a sys-usb?
I have documented the Layout of the USB controllers here:It shows which USB Controllers connects to which external USB Port and which internal USB Devices like Camera / Bluetooth / LTE-Card belongs to which USB Controller.Depending on which USB Controller you attach to a VM, you pass along all attached internal USB Devices.Therefore I am a using a sys-usb Qube ;-)Regarding the other questions, I'll try to answer this later.
1. That first USB device, which does not state where it can be used is either:a) The USB 2.0 interface "available" via the expresscard interface (some "expresscard" devices are really just USB 2.0 devices).b) The USB 2.0 interface available via the docking connector....some experimentation should lead to clarification.
2. On my W520, I typically only attach the USB 2.0 controller to sys-usb (via PCI). That way, if I have to directly attach a storage device to a VM for IO-intensive uses, I can utilize a disposable HVM and attach the USB 3.0 controller directly to it.
3. Lastly, for those worried about having a flexible USB controller PCI layout (the ability to assign different controllers to different HVMs), there's a secret I'll share: the expresscard port on both the X230 and the W520 is a PCI port! And there are expresscards that provide USB 3.0 ports! Granted expresscard's maximum signaling rate of 2500Mbps is not quite 6000Mbps maximum of USB 3.0...but definitely faster than 480Mbps! The W520 puts PCI devices mounted via the expresscard slot in their own grouping (e.g. a USB 3.0 expresscard)...again, experimentation will show whether the X230 does as well.

You are very likely right, I have always asked myself why there is an USB Controller which has no internal devices attached and doesn't connect to any of the external USB slots. I have a docking station, so I will test this.
2. On my W520, I typically only attach the USB 2.0 controller to sys-usb (via PCI). That way, if I have to directly attach a storage device to a VM for IO-intensive uses, I can utilize a disposable HVM and attach the USB 3.0 controller directly to it.The problem is, that the USB 3 Controller on the X230 has also the internal WWAN Card connected, so of I attach it to an AppVM and not the sys-usb Qube I am not able to pass the WWAN Card to my sys-net VM and use LTE, which I need to rely on.

It's the dock.
I use 3 disposable USBVMs, each allocated 1 controller.
The I proceeded withe installation. And later during setup I got this message:
sys firewall failed....
And then:
Start faild... Could not find capabilites for arch=x86_64
The later is refering to missing hardware i gues.
Can coreboot be installed on T580, have you ever heard of such?
HVM/VT-x/AMD-V...... Interupt Remapping
Do you know what it referes to? Perhaps it can fixt in Bios?
The 2170 is even smaler than the X230.It might lack other fetures tough. If it even works.
By the way I just got some first hand experience concerning why its a good idee to instal coreboot: When trying to enter Bios on the 2170 a pasword verification showsup! I dont think this is there by defult. So I guse some one at some point alterd bios.
After considering it I think every one sould get corboot. Its not that unlickly that some one at some point could have put some kind of program in there. After all its an old computer with many users and also a prime computer for both people that know how to infect bios and peple consernd about there privacy. So watch out!
but then again I gues you would have to trust the people behind corboot. catch 22. Or is it?
Any way its cool how easy an inexpensive it is to get up to 16 Ram on both models! cost close to nothing. my old setup hade 8 ram and couldent handel more than 4 VM or something like that.
