runtime Changes
Highlight changes:
- 9pfs in the guest is now mounted with
cache=mmapoption that provides better mmap related POSIX compliance. - Guest entropy source can be configured via the
entropy_sourceoption and it defaults to the/dev/urandomhost device. - Guest max memory slot number can be configured via the
memory_slotsoption. - GPU device is now supported
- A new
kata-netmonprogram is added and it is invoked bykata-runtimeto monitor container netns on the host and relay any network changes to the guest. kata-runtime updatesubcommand now supports adding extra memory to a running container.vhost-netis now optional and can be disabled via thedisable_vhost_netoption.

Release 1.3.0-rc1
Welcome to Kata 1.3.0-rc1.
Now the containers get entropy via virtio-rng. This helps to get a good quality of random number generation.
The agent has optional seccomp support, this will enable seccomp in the future in Kata. The ksm-throttler fixed install paths to do not have file conflicts with Clear Containers installations.
