[[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!"

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

RHEL and Fedora Virtualization Feature Parity

Robert Day wondered how the virtualization features[1] of Red Hat Enterprise Linux 5.4 compared to Fedora 12.

Daniel Berrange explained[2] "The KVM based virtualization in RHEL-5.4 is not nearly so far behind Fedora as you might think. The Package-x-generic-16.pnglibvirt mgmt stack in RHEL-5.4 was rebased to be near parity with 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."
