The Xen Project has released version 4.11 of its hypervisor.
As we reported last week, it’s more than a month late, but the projects leaders thinks it is worth the wait because this release delivers on an ambition to “create a cleaner architecture for core technology, less code and a smaller computing base for security and performance.”
A big part of delivering on that is increased use of PVH – a type of virtualization that Xen reckons blends the best of paravirtualization (PV) and Hardware Virtual Machines (HVM).
PV virtualizes hardware so a guest can offer kit not found on its host, but doesn’t use virtualization extensions in silicon.
HVM can use those extensions and therefore offers each VM isolated emulated hardware.
Xen 4.11 comprises contains 1206 commits from 406 patch series.
