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

| − | [[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>.

| − | 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.

| + | "The KVM based virtualization in RHEL-5.4 is not nearly so far behind |

| − | '''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
