Hi everyone,

I have a question about **`goa run`**. When I run `goa run`, does it start a QEMU instance under the hood? If so, how can I adjust the QEMU parameters?

For example, I’d like to configure QEMU in a similar way to using the `QEMU_OPT` option in `genode/build/x86_64/etc/build.conf`. Is there a way to explicitly set the QEMU options used by `goa`?

Thanks in advance for your help!

`goa run` does not feature a QEMU run backend yet, only base-linux and Sculpt OS as a remote test target are supported (see _share/goa/lib/run/_). I think adding a QEMU backend down the road would be a welcoming addition.

That being said, if testing in QEMU is essential for your test-case, you could try to combine running Sculpt executing the _goa\_testbed_ preset within in QEMU and using goa’s Sculpt remote test target backend.

OK, thanks for your answer. I’ll try.
