<p class="MsoNormal"><span style="font-size:11.0pt">The 1.7.0 release of Kata Containers is now available. The
<a href="https://github.com/kata-containers/runtime/releases/tag/1.7.0">1.7.0 release</a> of Kata Containers includes a few optimization fixes, updated Firecracker support, as well as an early experimental preview of virtio-fs.<o:p></o:p></span></p>

<span style="font-size:11.0pt">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.<o:p></o:p></span></li><li class="MsoListParagraph" style="margin-left:-15.75pt;mso-list:l0 level1 lfo1">
<span style="font-size:11.0pt">Experimental virtio-fs support: </span><span style="font-size:11.0pt;color:#24292E">virtio-fs is a shared file system that lets virtual machines access a directory tree on the host. In Kata Containers, virtio-fs can be used to
share container volumes, secrets, config-maps, configuration files (hostname, hosts, resolv.conf) and the container rootfs on the host with the guest. virtio-fs provides significant performance and POSIX compliance improvements compared to 9pfs. Enabling of
virtio-fs requires changes in the guest kernel as well as the VMM. For Kata Containers, experimental virtio-fs support is enabled through the <a href="https://github.com/intel/nemu"><span style="color:#0366D6">NEMU VMM</span></a>. See the
<a href="https://github.com/kata-containers/documentation/blob/master/how-to/how-to-use-virtio-fs-with-kata.md">
Kata Containers with virtio-fs</a> document for details on how to get an initial look at virtio-fs support.</span><span style="font-size:11.0pt"><o:p></o:p></span></li><li class="MsoListParagraph" style="margin-left:-15.75pt;mso-list:l0 level1 lfo1">
