Having just installed Qubes 4.0.1 I am not able to get my 10Gb Intel X540-AT2
network card to work. It worked out of the box in Qubes 3.2.
This is what I get in the net-vm:

Thanks a lot. Upgraded to Fedora-28 now, hopefully problem solved :)
I'v been running Qubes 3.2 for a long time and never had problems with crashing
Suddenly one of my appvms based on Fedora 2.6 has begun to randomly shut down
on me. It seems to be related to me using the gnome file manager (related to
file activity on mounted samba shares?).

Having Qubes automatically give the titlebar of the windows the same coulour as
defined for the VM is a nice thing.

Just a quick note to see if anybody have experienced similar problem:
Connecting an old Samsung Galaxy S3 phone to my app-vm using "qvm-usb -a" works
just fine. I can connect to the phone via adb in the appvm.
Trying to connect a new Samsung Galaxy S7 Edge the same way, the "qvm-usb -a"

Is it possible to get the VMs to use 10Gb network? (or is the link

Yes, I know about Qubes-network-server, but I was hoping to get this working

I have now found the very slow GUI described in my previous thread
https://groups.google.com/d/msg/qubes-users/gzS8Zc9StxQ/gSwEC-fdFAAJ to be a
direct result of installing the qubes-windows-tools into the VM.
That's why I'm starting a new thread focusing on this problem here.

Thank you for your detailed answer. I realise that number of vcpus to choose is
a hot topic.
In my 32 core system,if I give a vm 3 vcpus, does this mean that this vm will
never be able to exceed 1/10th of the system's total cpu power?

Currently my Windows 7 StandaloneVM feels a bit sluggish.
Moving windows (no phun intended) is a pain.
Is it possible to have a Windows VM without any lag, or is this just a part of
the deal with Qubes OS?
What tweaks should I do to get my Windows VM as responsive as possible?
I have no

I am unable to install SEH UTN Manager

I have tried both with/without QWT installed.
The problem seems to be related to signing of the driver, see attached
