Kata Containers 1.7.0

Release 1.7.0

The 1.7.0 release of Kata Containers includes a few optimization fixes, updated versions support, as well as an early experimental preview of virtio-fs.

We improved the implementation of k8s empty-dir(ephemeral volumes) based on host directories by creating these inside the VM itself. If the VM is using device mapper for container storage, the containers will benefit from the better performance of device mapper for host emptyDir.

virtio-fs is being developed as a replacement for 9pfs, providing better performance and compatibility for workloads which require host to guest filesystem sharing. While there are several limitations with the implementation currently, users can take a first look at the virtio-fs getting started page.

Other highlights include:

• Kata now supports the latest Firecracker, version 0.16.
• Initial persist API changes were added as well, providing an initial baseline for hot upgrade.
