From: Marc-André Lureau <marcandre.lur...@redhat.com>Add qemuVhostUserFetchConfigs() to discover vhost-user helpers. qemuVhostUserFillDomainGPU() will find the first matching GPU helper with the required capabilities and set the associated vhost_user_binary.
Looks good, but it seems like something we might want to start caching over time, especially if more than one helper per domain will be needed.

Not sure about the placement in DeviceInfo, looks more fit for 'driver' to me. Jano
