VIRTUALIZATION --
The libvirt virtualization API saw a major 3.0 release this week to succeed its earlier v2.5 milestone.

Libvirt 3.0 was released rather quietly but does come with a number of additions and improvements. Among the libvirt 3.0 changes I found worth mentioning include:

- Support for QEMU group I/O throttling.

- A new libvirt_guest NSS module for translating libvirt guest names into IP addresses.

- Event notifications for the secret object.

- Various new APIs around storage and vCPUs.

- Support for guest CPU configuration on s390(x).

- More perf statistics are supported.

- Virtio-PCI is now enabled by default for AArch64 Mach-Virt guests.

- Various bug-fixes and other minor improvements.

Those using libvirt as part of their Linux virtualization stack can learn more about libvirt 3.0 via Libvirt.org.
