Welcome to Kata Containers release 1.6.0, which includes:
-Add OpenTracing support
This release includes preview changes to support OpenTracing
-As part of the changes to enabled virtio-fs, now the agent can mount virtio-fs shared directories
-The agent allows cpuset request that not match with vcpus in the guest
-Kata Containers project updated to the Linux Kernel 4.19.x as preferred kernel version
-Now Kata supports NVDIMM on arm64
-Now cpu cgroups in sandbox are honored: This includes user defined paths and limit hypervisor vCPU threads

agent Changes

  • Add OpenTracing support
    This release includes changes to support OpenTracing, but note that the feature should be considered a preview as it is not yet integrated into the runtime. See and #1369 for full details.
  • mount: add virtio-fs mount driver
    Now the agent can mount virtio-fs shared directories.
  • Agent allow with cpuset that not match with vcpus in the guest.
