If that works fine, and guest apps/libraries are using that as a fallback anyway, what benefit do they get from switching to virtio-serial when they detect that instead, given they still have code for the -net method? Is the plan to remove -net user based support from libguestfs? Is virtio-serial significantly simpler to use? -- Jamie -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
