==== New Options for Guest Cloning ====

Cole Robinson posted<ref>http://www.redhat.com/archives/et-mgmt-tools/2009-February/msg00051.html</ref> a patch to enable <code>virt-install</code> to
 
"build a guest around an existing disk image, skipping the OS install step."
 
Cole also
 
posted<ref>http://www.redhat.com/archives/et-mgmt-tools/2009-February/msg00050.html</ref>
 
a patch for <code>virt-clone</code> which allows for cloning from an XML file
 
"rather than require the use of a guest defined on the current connection."

==== Obtaining Guest IP Address from the Host ====
 
Thomas Mackell inquired<ref>http://www.redhat.com/archives/et-mgmt-tools/2009-February/msg00036.html</ref> about a way to obtain the IP address of a guest that was easier than logging into it and running <code>ifconfig</code>. Cole Robinson pointed out {{package|virt-mem}}<ref>http://et.redhat.com/~rjones/virt-mem/</ref> which is a collection of utilities for interrogating <code>KVM</code> guests. Tools included are
 
<code>virt-uname</code>, <code>virt-dmesg</code>, <code>virt-ps</code>, and <code>virt-ifconfig</code>.

"Basically when creating a storage volume, you just need to pass information about the backing storage volume. It'll thus create a volume which is a snapshot of this backing store."

This allows guests to independently appear on the same network as the host machine."

Fedora Virt Status Update

TODO[1]

Improved Guest Mouse Pointer Movement

Daniel P. Berrange announced[1] an improvement to mouse pointer movement in Fedora 10 and 11 KVM guests.

"The default mouse for KVM guests is a PS/2 mouse. This causes pain for users because it only works with relative coordinates, which means we are forced to grab the mouse pointer in the VNC client.

KVM can emulate a USB graphics tablet which works in absolute coordinate mode, and thus gives flawless mouse motion tracking without needing any grab in the client." [2]

USB tablet will now be used by default Package-x-generic-16.pngpython-virtinst in F11.

Approved F11 Virtualization Features

Chris Lalancette relayed[1] the outcome of the FESCO meeting on February 27[2] as it relates to virtualization.

At this time, the list of features approved for inclusion in Fedora 11 are:
