Hi Samuel,

We use it all the time. To see if there had been an upstream regression I
just tried latest qemu (v3.0.0-1763-gb2f7a038bb4c) with a latest kernel
(v4.20-rc1) in my guest. It worked just fine, and there was no need for
any kernel command line parameters.

What guest kernel version did you try?

Thanks,
