| ==== KSM Tuning Daemon and the KSM Kernel Thread Process ==== | | ==== Virt Status Report ==== |

| | posted<ref>http://www.redhat.com/archives/fedora-virt/2009-December/msg00056.html</ref> a Fedora virtualization status report. |

| enabled with chkconfig. After starting more guests, <code>ksm</code> was found to be
| |
| running.
| |
| | |
| [[DanKenigsberg|Dan Kenigsberg]]
| |
| added the follwing explaination to the KSM feature page<ref>http://fedoraproject.org/wiki/Features/KSM</ref>
| |
| "Fedora's kvm comes with 2 services controlling the behavior of <code>ksm</code>. One,
| |
| simply called <code>ksm</code>, is just a nice means to start and stop ksm's kernel thread.
| |
| The other, called <code>ksmtuned</code>, controls the first service and tunes its
| |
| parameters according to the memory stress that is generated by KVM virtual
| |
| machines. <code>ksmtuned</code> may stop <code>ksm</code> service alltogether, if memory is not in need.
| |
| Later, if <code>ksmtuned</code> senses that memory stress has risen, it will fire up <code>ksm</code> again."
| |
| | |
| Soon after the explaination, Dan posted a patch<ref>http://www.redhat.com/archives/fedora-virt/2009-November/msg00068.html</ref>
| |
| which will cause <code>ksmtuned</code> to log any <code>ksm</code> state changes. This patch will soon be available in an update.
| |
| | |
| KSM was also recently covered in FWN 200<ref>http://fedoraproject.org/wiki/FWN/Issue200#KSM_Tuning_in_Fedora_12</ref>.

| ==== New Release virt-manager 0.8.1 ====
| |
| [[ColeRobinson|Cole Robinson]]
| |
| announced<ref>http://www.redhat.com/archives/fedora-virt/2009-December/msg00003.html</ref> new releases of {{package|virt-manager}} 0.8.1 and {{package|python-virtinst|virtinst}} 0.500.1.
| |
| | |
| Virtual Machine Manager<ref>http://www.virt-manager.org/</ref> provides a graphical tool for administering virtual machines, using {{package|libvirt}} as the backend management API.
| |
| | |
| <code>Virtinst</code> is a python module that helps build and install <code>libvirt</code> based virtual
| |
| machines. Currently supports KVM, QEmu and Xen virtual machines. Package
| |
| includes several command line utilities, including {{command|virt-install}} (build
| |
| and install new VMs) and {{command|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
| |
| | |
| "Thanks to everyone who has contributed to this release through testing,
| |
| bug reporting, submitting patches, and otherwise sending in feedback!"
| |
| | |
| Also see coverage of the release on linux-kvm.com<ref>http://www.linux-kvm.com/content/virt-manager-081-released</ref>.
| |
| Version 0.8.0 of <code>virt-manager</code> was announced<ref>http://fedoraproject.org/wiki/FWN/Issue187#New_Release_virt-manager_0.8.0</ref> on July 28th, 2009.

| | ==== RHEL and Fedora Virtualization Feature Parity ==== |
| | Robert Day wondered how the virtualization features<ref>http://www.redhat.com/virtualization/rhev/</ref> of Red Hat Enterprise Linux 5.4 |
| | compared to Fedora 12. |
|
| |
|
| | [[DanielBerrange|Daniel Berrange]] |
| | explained<ref>http://www.redhat.com/archives/fedora-virt/2009-December/msg00040.html</ref> |
| | "The KVM based virtualization in RHEL-5.4 is not nearly so far behind |
| | Fedora as you might think. The {{package|libvirt}} mgmt stack in RHEL-5.4 was |
| | rebased to be near parity with [[Releases/11|Fedora 11]], and KVM in RHEL-5.4 is |
| | also pretty close to that using what's best described as a hybrid of |
| | kvm-83 and kvm-84." |
