In this section, we cover discussion of Fedora virtualization technologies on the @et-mgmnt-tools-list, @fedora-xen-list, and @libvirt-list lists.

Adding a VM to Virtual Machine Manager

Dennis J. asked^[1] "How do I add a custom-built vm to virt-manager?"

This is a two step process with a few ways to accomplish them.

Create an XML representation^[2] of the guest, or domain, configuration.
Import this definition into libvirt. i.e. virsh define guest.xml

The virt-image^[3] tool was suggested and worked for Dennis. There is also a perl script^[4] that can be used to create an XML definition from the set of qemu-kvm command line arguments used to create the guest. There is a public API in libvirt for converting back and forth between the native hypervisor configurations and XML representations.^[5]

Finally, virt-install added an --import option which allows creating a guest from an existing disk image, bypassing any OS install phase.^[6]

libosinfo: Library for Virt OS/distro Metadata

Cole Robinson posted^[1] a request for comments on "the initial work for a new library, libosinfo^[2] (better name recommendations appreciated). This library will provide OS meta data for use in virt applications, replacing the dictionary we currently keep in virtinst." The work was based on a post^[3] by Daniel Berrange.

Libvirt List

VNC Authorization per Guest

Christian Weyermann asked^[1] how to restrict "users to only be able to connect to their own virtual machines via VNC."

Daniel Berrange said "there is no way to specify authorization data on a per-VM basis. So if you authenticate successfully you have access."

Hugh Brock added^[2] "It is on our wish list for Real Soon Now, but we haven't identified anyone to actually do the work yet... patches welcome :)"
