Fabiano Fidêncio f21c54a985 kata-deploy: QEMU, for 2.x, already includes virtiofs 
There's no reason to ship qemu & qemu-virtiofs when the former already
includes vitiofs support (and that's the default for 2.x deployments).

In case we will enable experimental qemu DAX support, we should add a
new target, a "qemu-experimental" target, as Carlos has been working on.

Fixes: #1424

Kata Containers with virtio-fs

Introduction

Container deployments utilize explicit or implicit file sharing between host filesystem and containers. From a trust perspective, avoiding a shared file-system between the trusted host and untrusted container is recommended. This is not always feasible. In Kata Containers, block-based volumes are preferred as they allow usage of either device pass through or virtio-blk for access within the virtual machine.

As of the 2.0 release of Kata Containers, virtio-fs is the default filesystem sharing mechanism.

virtio-fs support works out of the box for cloud-hypervisor and qemu, when Kata Containers is deployed using kata-deploy. Learn more about kata-deploy and how to use kata-deploy in Kubernetes here.
