[olug] Announcing Fedora 13 (fwd)

[Dan Linder]

Concerning the BTRFS and Virtualization enhancements mentioned...

Is BTRFS stable enough to start playing with on a day-to-day basis, or is it
still too experimental?  (FWIW, I use VMWare workstation heavily on my
workstation so loosing a 2GB slice of my drive means I'm restoring all 24
2GB slices.)  I've been really jealous of the Solaris guys with their ZFS
snapshots, so this may be my best option under Linux.

I've used VMWare Workstation and VirtualBox to host my Linux and Win2K3
systems.  Is KVM a candidate to host a Windows 2003/2008 (preferrably 64bit)
system, or is this version of KVM not happy playing host to these guests?

* Btrfs snapshots integration. Btrfs is capable of creating
>  lightweight, copy-on-write filesystem snapshots that can be mounted
>  (and booted into) selectively. Automated snapshots allow system
>  owners to easily revert to a filesystem from the previous day, or
>  from before a yum update using the yum-plugin-fs-snapshot
>  plugin. Btrfs is still an experimental filesystem in this release
>  and requires a "btrfs" installation option to enable support for
>  it. (This option is only available for non-live images.) Upcoming
>  releases will integrate the snapshot functionality into the desktop
>  while working on stabilization of the filesystem in parallel. Thanks
>  to Josef Bacik, Btrfs filesystem developer at Red Hat, for
>  filesystem work and the new yum plugin and Chris Ball from OLPC team
>  for leading this effort.

> * Virtualization enhancements. Fedora continues its leadership in
>  virtualization technologies with improvements to KVM such as Stable
>  PCI Addresses and Virt Shared Network Interface technologies. Having
>  stable PCI addresses will enable virtual guests to retain PCI
>  addresses' space on a host machine. The shared network interface
>  technology enables virtual machines to use the same physical network
>  interface cards (NICs) as the host operating system. Fedora 13 also
>  enhances performance of virtualization via VHostNet acceleration of
>  KVM networking, Virtx2apic for enhanced guest performance on large
>  multi-processor systems, and Virtio-Serial for simple IO between the
>  guest and host user spaces. Thanks to the Red Hat virtualization
>  team for their ongoing contributions.
