Fedora 11: Virtual(ization) Reality

Filed under
Linux
Interviews

Cutting edge virtualization technology has always been one of Fedora's strong suits and Fedora 11 looks to continue that trend. In an interview with Daniel P. Berrange, Red Hat Virt Team Engineer and Fedora Virtualization guru, we talk about the many key upgrades to virt technology in F11 focusing on areas of usability, performance and security. Fedora 11 will premiere the latest in secure and powerful virtualization technology available to users and developers. With so much to look forward to Fedora 11, it's sure to make your virtualization dreams a reality.

Many people view the work being done on virtualization as a feature set of major importance and significance. Can you give us a brief overview of some of the changes we can expect to see in Fedora 11?

The open source virtualization development effort is so large now, that it is useful to discuss each stream in turn.

At the lowest layer is obviously the Linux kernel and KVM/QEMU. There has been a major acceleration of development in QEMU and push to merge KVM into the official QEMU source repository. There's ever continuing work on performance, stability, scalability and reliability in KVM. PCI device passthrough is one new feature we're highlighting for Fedora 11. The return of Xen Dom0 was not to be, as the Dom0 paravirt_ops merge with the upstream Linux kernel is still an ongoing process.

At the middle layer is libvirt, providing a consistent management API across different virtualization technologies.
