qcow2, raw, COW
by Gene Czarcinski
I am not sure if this is the correct mailing list so if it is not, point
me to the correct one.
I am a fan of the BTRFS filesystem and even use a subvolume for
/var/lib/libvirt/images. Now, if you don't do anything, the disk image
files are going to be hugely fragmented and get even more fragmented
over time since BTRFS is a copy-on-write filesystem. I thought I knew
how this stuff worked but apparently I do not because it does not
currently work for me on Fedora 20 with current updates (not the preview
although I will likely install that "real soon now").
1. To disable C-O-W I did "chattr +C /var/lib/libvirt/images" but new
files are showing large fragmentation.
2. I want the default disk image format to be raw rather than qcow2. On
one of my systems, new disk images default to raw. On another system,
new disk images default to qcow2. Both are Fedora 20 and I did nothing
to either.
3. I tried: "sudo virsh pool-edit default" and adding "<format
type=raw'/>" to the definition for <target>. The command executed with
no errors when I did ":wq" but the definition was *not* changed.
Are these bugs I need to report or is there something I need to do.

virt-preview enabled for Fedora 21 branch
by Cole Robinson
Hi all,
I've turned on the virt-preview repo for the Fedora 21 branch now. So if you
start running F21 packages/prereleases, virt-preview will continue to work
fine. The builds are tracking rawhide.
Another change is that F20 virt-preview is now tracking F21 package versions.
This doesn't matter in practice yet, since F21 and rawhide will be in sync for
quite a while. But when rawhide eventually diverges (probably after F21 beta),
F20 virt-preview will still be shipping the rebuild F21 packages. The point is
to ensure a bit more testing for packages that will be shipped in the F21
final release.
As usual, F20 virt-preview will no longer receive new builds after the F21
final release.
More info about the virt-preview repo:

Thanks,

qemu 2.1-rc0 in rawhide
by Cole Robinson
I've built qemu 2.1-rc0 for rawhide now, it should show up in virt-preview
tomorrow. New versions of openbios and SLOF were also pushed, to match what
should be shipping with qemu 2.1 GA
There's a issue with some of qemu's output that libvirt depends on for probing
capabilities, so libvirt might refuse to start up some of your VMs, detailed here:
https://lists.gnu.org/archive/html/qemu-devel/2014-07/msg00882.html
Once a fix exists I'll pull it in ASAP
Thanks,

Virtualized desktop
by Jimmy Thrasibule
Hi,
I'm looking to renew my hardware and I'm wondering how Fedora can help
me to virtualize my desktop environment.
My first go was to have 2 Intel NUC (or Gigabit BRIX) and 2 screens,
one computer more stable and one I can play with. I want to use both
screens with both
computers so this implies to also have two KVMs.
Then came the idea to virtualize everything. Make both computers a
hypervisor cluster (using Xen or KVM) and run all systems virtualized.
But at which point can this be done for desktop system?
Here are some points I'm blocking with:
1. I want two screens and be able take make each VM to use one (left
or right) or both screens. Maybe by pressing some keyboard shortcuts.
2. I want mouse a keyboard to be moved to the VM of my choice or
dedicated to one VM and use Synergy [1] for the others.
3. I will have somewhere a Windows VM so good support is needed.
4. What about the graphics? Can I still make use of Blender for
example? How the graphic card shared between each VM?
5. I'd like to make both hypervisor work together. Can I use the local
drive of each computer to ensure migration and folder sharing?
I see many advantages which this setup:
1. I can freely test, new VM and we are done.
2. I can make a snapshot at any time just in case and go back if my
system crashes.
And some drawbacks:
1. I will never have full performance of my hardware.
Is it for you something that can be done or no way?
