Disable Virtio-FS Metadata Cache
Disable Virtio-FS Metadata Cache

With metadata cache set to "always" or undefined (should default to
auto) the memory usage of virtiofsd will grow larger than memory
allocated to the Pod. The memory overhead allocated to the Pod over the
guest VM is pretty small, and virtiofsd can easily take up 200Mb itself
with a directory structure that has a lot of files in it.
