Virtualization

In this section, we cover discussion on the @et-mgmnt-tools-list, @fedora-xen-list, @libvirt-list and @ovirt-devel-list of Fedora virtualization technologies.

Fedora Virtualization List

This section contains the discussion happening on the fedora-virt list.

Fedora Virtualization Status Report

Mark McLoughlin's status report[1] this week reminds us that the final development freeze[2] for Fedora 11 is coming up on April 14, 2009, and "there's a huge pile of bug-fixing and polish work to do".

"If you're looking to help out, there's no better place to start than the F11VirtBlocker[3] and F11VirtTarget[4] tracker bugs."

Read on for more coverage of virtualization developments in the past week.

Using kvm-autotest to test Fedora KVM

Mark McLoughlin explained[1] "upstream KVM developers are working hard on a suite of regression tests for KVM. It would be hugely helpful if people could run kvm-autotest[2] on their own machines to try and catch as many KVM issues as possible." Mark also provided a howto[3].

Fedora Xen List

This section contains the discussion happening on the fedora-xen list.

Experimental Dom0 Kernel Update

Michael Young announced[1] his repository[2] "is up to kernel 2.6.29-1.2.18.fc11. This one is based on push2/xen/dom0/master[3] rather than xen/dom0/hackery which should be closer to what is proposed for the 2.6.30 merge. It also has CONFIG_HIGHPTE=n (for x86), but my attempts to add squashfs 3 in addition to squashfs 4 didn't work as it seems you can't build both."

Libvirt List

This section contains the discussion happening on the libvir-list.

New Release libvirt 0.6.2

Daniel Veillard announced[1] a new libvirt release, version 0.6.2.

"This is mostly a bug fix release, though it also includes a few new features and some improvements:"

New features:

  • support SASL auth for VNC server (Daniel Berrange)
  • memory ballooning in QEMU (Daniel Berrange)
  • SCSI HBA storage pool support (Dave Allan)
  • PCI passthrough in Xen driver (Daniel Berrange)

Improvements:

  • get CPU usage info for LXC (Ryota Ozaki)
  • fix domain RNG to add ac97 and tests (Pritesh Kothari)
  • OpenVZ support for non-template filesystem root (Florian Vichot)
  • improve arch capabilities generation (Daniel Berrange)
  • modularization of spec file (Ryota Ozaki)
  • better error reports in SEXPR generation (Daniel Berrange)
  • support for vifname parameter in VIF config (Daniel Berrange)
  • localtime handling for new xen (Daniel Berrange)
  • error reporting/ verification of security labels (Dan Walsh)
  • add --console arg for create and start virsh commands (Daniel Berrange)
  • refresh volume alloc/capacity when dumping XML (Cole Robinson)

This release comes one month after the release of 0.6.1[2].

Daniel Veillard referred[3] to the scheduling conversation last week (FWN#169[4]) when reitterating the plan for a feature freeze around April 17th and a release of 0.6.3 around April 24th.

"Plannned so far for 0.6.3 are:

  • API for physical host interface
  • the VirtualBox driver if in shape and in time

but that's not an exhaustive list and there is a couple of drivers submitted I need to look at (OpenNebula for example)."

First Release netcf 0.0.1

Less that 3 months since compsing the RFC(FWN#159[1]) David Lutterkort announced[2], the release of netcf[3] 0.0.1. This is "the initial release of a library for managing network configuration in a platform agnostic manner. If I were into code names, this would be the 'what have you been waiting for' release."

"Netcf does its work by directly modifying the 'native' configuration files of the host it is running on; this avoids a whole class of problems caused by similar approaches that do network configuration behind the back of the native mechanisms. The API allows listing of configured interfaces, defining the configuration of an interface, retrieving the same (regardless of whether the interface was initially configured with netcf or not), and bringing interfaces up and down. This functionality is needed both by libvirt and NetworkManager, so it seemed only logical to move their common needs into a separate library."

Read the announcement for more info such as the new mailing list for netcf development discussion and where to find test builds for Fedora 10.
