Hi Samuel,<br>
<br>
I am not sure if this is related to the issue you are facing, but<br>
sometimes, I face issues with qemu when it conflicts with kvm kernel<br>
module. I tend to remove kvm modules from kernel to get qemu properly<br>
working with Barrelfish.<br>
<br>
On intel machines<br>
sudo rmmod kvm_intel<br>
<br>
And on ADM machines<br>
sudo rmmod kvm_amd<br>
<br>
You might want to try this and see if it helps.<br>
