The idea was discussed here before, so I'll keep this short.
We've set up a repository for people running Fedora 11 who would like
to test the rawhide/F12 virt packages. To use it, do e.g.
$> cat > /etc/yum.repos.d/fedora-virt-preview.repo << EOF
name=Virtualization Rawhide for Fedora 11
$> yum update
At the moment, it contains the F-12 versions of libvirt and qemu, but
as F-12 development continues, it will contain more. I'll send periodic
mails to the list detailing the latest updates.
Also, this is very much a work-in-progress. The TODO list includes:
- get createrepo installed on fedorapeople.org
- include debuginfo packages in the repo (need more quota)
- find a better location than markmc.fedorapeople.org
- enable package builders to upload directly to the repo
- automatically do preview build/upload for devel/ builds
- allow building against preview packages; e.g. for language bindings
Comments most welcome. Help with the TODO list is even more welcome :-)

Long before I ever tried using virtual machines, I painstakingly
came up with some iptables settings to make my system as closed
as possible to most of the outside world while still being open
to my local 192.168.1.0/24 network.
I'm now playing around with VMs on my system, using bridging
because I want each VM to be a fully fledged member of my
It works great as long as I turn off iptables on the host, so
now I wonder what the heck is preventing the bridge traffic
from operating? (Actually it is just the VMs that can't
get out - I get can into them OK).
Do I have to tell the host to forward everything (rather than
forwarding nothing as I have it now?).
This is on a F11 x86_64 host WITHOUT virt-preview.
This happens with F11 and F9 guests (both 32 bit and 64 bit architectures).
Installing and bootup works fine with the default NIC. But, when I add a
second NIC (such as a privately network), I hang for a long time at Starting
The NICs mostly specify a "virtio" device but this also occurs if you specify
something else. Both NICs use the same device type.
At first I thought I was really hung but waiting a long time (at least a
minute) breaks free and everything proceeds normally.
This does not happen on real hardware ... I have one system with two NICs and
another with three NICs are n\there are no "long pauses".
I have built a new set of kernel packages based on fedora rawhide
kernels and the xen/dom0/hackery branch of Jeremy's git repository
( http://git.kernel.org/?p=linux/kernel/git/jeremy/xen.git;a=summary ).
This batch (kernel-2.6.29-0.114.2.6.rc6.fc11) is available via the koji
build system at
These are really for development and debugging purposes only, as I am
still having problems getting them to boot, but others have reported more
success at getting kernels based on this git repository working, so you
might be lucky.
Note to install these packages on Fedora 10 you will need to have
rpm-4.6.0-1.fc10 installed (currently in updates-testing but it should be
available in updates soon) because of the change to SHA-256 file digest
hashing in recent Fedora 11 builds.
I was able to install and run F12 alpha (just the packages on the DVD) on F11
plus current maintenance qemu-kvm.
I also tried F12 alpha on F11 + virt-preview ... I could install (if I
specified the system was F9) but the guest immediately reset just after the
"udev" message. I copied the .img and .xml files from the other system (where
it ran successfully) and it also died.
Is this a known problem? Any suggestions on data to look at?
I would like to install FE V12 and try out the integrated to the virt
manager changes. There are several download options, however, I do not see
a complete DVD install disk. If I just download the boot.iso and install
does than imply I will then need to go back and add packages one by one to
re-establish where my DVD installed FE V11 is today? Is there any
difference between the the latest Rawhide and FE V12 alpha at this point?
Finally, can I migrate to FE 12 or is this a complete reinstall meaning I
need to preserve my current VMs and other data on my hard drive which only
has one partition? I plan to fix this scenario later but for now OS and
data is on one disk.
