vm/qemu: audio initialization fails

when I run syz-manager -config=my.cfg, the error comes. How to solve this problem?

Hi, Try to add the following param to vm config: "qemu_args": "-enable-kvm"

I have solved the problem, Thank you! @dvyukov

[dvyukov]

Thanks for testing.

We probably need to make "qemu_args": "-enable-kvm" the default. And then let people who are interested in device testing to add the additional flags manually.
So I am keeping this issue to make the change.

This seems to be fixed.
