I confirm that. Same dmesg log all over the place trying to use KVM with
a VIA Nano U2250.

[Qemu-devel] [Bug 712416] Re: kvm_intel kernel module crash with via nano vmx

[Serge Hallyn]

Thanks for reporting this bug and helping to make Ubuntu better.

A bit of searching suggests that VIA Nano was until recently very little
tested and supported.   The kernels you are working with are rather old
compared to upstream.  So in order to see whether you should be talking
to us or kvm upstream, could you please test this with the latest daily
kernel build (see http://kernel.ubuntu.com/~kernel-
ppa/mainline/daily/current/) and the latest qemu-kvm build (see
https://launchpad.net/~ubuntu-server-edgers/+archive/server-edgers-qemu-
kvm).

[khetzal]

yes this appears to be a duplication but the original bugreport has been
posted one year ago and there is no evolution. Moreover, it's not posted
on the officiel qemu / kvm bugtracker ;).

I'm waiting that my current installation complete and i test the new
kernel / kvm, but i've tested one week ago with the linux kernel kvm git
branch and the git master version of kvm, and it crashed directly.

Thanks for testing.  Are you able to get in touch with the kvm
(kvm@vger.kernel.org) and linux-kernel (linux-kernel@vger.kernel.org)
mailing list to follow up with upstream?

It will not be duplication.  These are development lists, not support
lists, so you won't be filing a bug report.  Rather, report your
failures and ask whether (a) they are aware of it, (b) it is expected,
(c) anyone is currently working on support for via nano, and
(d) how others can help.

Not really. KVM module bugs should be reported to the kernel's bug
tracker as explained on http://www.linux-kvm.org/page/Bugs .

I can confirm this is still an issue. I have tried myself with this and
it crashes the whole system and has to be rebooted again to even get it
useable again.
