==== Connecting to VNC Console on Remote System Installs ====
While executing <code>virt-install</code> on a remote system, Stephan found[1]
that the installer created a VNC service listening on 127.0.0.1, and wanted to
know how to connect to this service or move it to a public interface on the
remote system.
 
[[DanielBerrange|Daniel P. Berrange]] answered[2] that
modifying the <code>vnc_listen</code> parameter in <code>/etc/libvirt/qemu.conf</code>
will affect the IP used, but this isn't necessary. The <code>virt-viewer</code> application will automatically tunnel[3] VNC connection over SSH.

==== Specifying Installation Media URLs ====
Contributing Writer: [[User:Dale | Dale Bewley]]
[[EnzoMedici|Enzo Medici]] became[1] frustrated while trying to provision Xen
domUs with <code>virt-manager</code>. "What constitutes a valid install media
URL?" "How do you get a valid install media URL for a particular Linux
distribution?"

"We actually don't have support in the backend for fetching kernels

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."
