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

On December 9th 9am EST to 6pm EST, Red Hat will be holding an online "event focused on Red Hat Enterprise Linux solutions, including virtualization and cloud computing." Titled "Red Hat Virtual Experience 2009" Attendees can participate in keynote sessions and "chats with business leaders, executives, key developers, customers, and strategic partners", and "learn what's on the horizon from Red Hat and industry partners—innovations in Red Hat Enterprise Linux, tools, security, and deployment in the cloud."
Fedora Virtualization List
This section contains the discussion happening on the fedora-virt list.
KSM Tuning Daemon and the Kernel Thread Process
added the follwing explaination to the KSM feature page
"Fedora's kvm comes with 2 services controlling the behavior of
ksm, is just a nice means to start and stop ksm's kernel thread.
The other, called
ksmtuned, controls the first service and tunes its
parameters according to the memory stress that is generated by KVM virtual
ksmtuned may stop
ksm service alltogether, if memory is not in need.
ksmtuned senses that memory stress has risen, it will fire up
Soon after the explaination, Dan posted a patch
which will cause
ksmtuned to log any
ksm state changes. This patch will soon be available in an update.
KSM was also recently covered in FWN 200.
New Release virt-manager 0.8.1
Virtual Machine Manager provides a graphical tool for administering virtual machines, using
as the backend management API.
Virtinst is a python module that helps build and install
libvirt based virtual
machines. Currently supports KVM, QEmu and Xen virtual machines. Package
includes several command line utilities, including
and install new VMs) and
virt-clone (clone an existing virtual machine).
New virt-manager Features:
- VM Migration wizard, exposing various migration options
- Enumerate CDROM and bridge devices on remote connections
- Can once again list multiple graphs in the manager window (Jon Nordby)
- Support disabling dhcp (Michal Novotny), and specifying 'routed' type for new virtual networks
- Support storage pool source enumeration for LVM, NFS, and SCSI
- Allow changing VM ACPI, APIC, clock offset, individual vcpu pinning, and video model (vga, cirrus, etc.)
- Many improvements and bugfixes
New virtinst Features:
- virt-install now attempts --os-variant detection by default. This can be disabled with '--os-variant none' (distro detection currently only works for URL installs)
- New --disk option 'format', for creating image disks formats such as qcow2 or vmdk
- Many improvements and bugfixes
