[SOLVED] Configurable vhost netdev option


New Member

In some cases, provisioning KVM instances with -netdev ...vhost=on will prevent the guests from being able to use the network stack. I would be great if this would be a configurable option, likely enabled by default (also to satisfy backwards compatibility).

The issue is referenced towards the bottom of this page: https://www.linux-kvm.org/page/UsingVhost as well as into more detail here: https://www.spinics.net/lists/kvm/msg37660.html

Thank you!

For most current use cases that's definitely a valid argument. For unikernel-like deployments however, it might not always be be the case given the deliberate decision not to bake a full blown kernel into the image. The same argument can be applied for them too :) The suggestion was not in spirit of applying a fix (as that is indeed not the case), rather expanding the range of supported guests.
