A brief description of Xen 3.4.1 and Libvirt 0.7.1-15 deployment to Fedora 12 follows bellow...

Install Libvirt 0.7.0 along with KVM creates environment with default Hypervisor QEMU . Two steps in procedure bellow makes Xen default Hypervisor on Ubuntu 9.10 . First is commenting out (xend-http-server yes) in /etc/xen/xend-config.sxp , second export variable VIRSH_DEFAULT_CONNECT_URI=”xen:///”.

Install Xen 4.0 and Libvirt like on F12 ([1]). Via my experience xend will hang for 5-7 min at startup and xen managed bridging will fail as well .At the same time PV guests won’t be able to obtain IP via interface virbr0. Workaround for the issue follows bellow.

Adam Williamson reports that the Fedora project is now producing automated nightly live builds of Rawhide, its development branch - now you can test the freshest Rawhide without having to install it at all.

Systemd, an alternative to Upstart or System V init, has made big strides since it was announced at the end of April. It has been packaged for Fedora and openSUSE, and for users of Fedora Rawhide, it gets installed as the default. There are still bugs to be shaken out, of course, and that work is proceeding, especially in the context of Rawhide.

Fedora 16 is more than two months away from final, stable release, but pre-Alpha installation ISO images have been floating around. News from the Fedora camp have already indicated that btrfs will be the default file system on Fedora 16, joining the ranks of MeeGo, the first (Linux) distribution to use btrfs as the default file system.
