eWEEK is reporting that the next stable release of the Linux kernel, version 2.6.21, will include a new feature submitted by VMware Inc. called VMI, or Virtual Machine Interface.
The initial promise of Virtual Machine Interface was that it would provide a common protocol across which multiple hypervisors could communicate with the Linux kernel instances they paravirtualize, as opposed to having different sets of hooks built into Linux for different hypervisors.
The idea is similar to the Linux Security Module framework, on which both the SELinux (Security-Enhanced Linux) and AppArmor rights-hardening technologies are built.
This is the second bit of virtualization-related kernel news in as many months. In February, Linux Torvalds made a splash after the Super Bowl when he announced that Kernel-based Virtual Machine (KVM) would be included in stable release 2.6.20.
