I had most of the packags, I ran "apt-get build-dep xen" from:
http://wiki.xen.org/wiki/Compiling_Xen_From_Source
But it still errors on the virtio file. I had also read that these
errors had to different with different library/gcc versions. Maybe
wheezy just has newer/different versions of those binaries/libs?

WELL, actually NO need to install Wheezy. I am very sure you can get it
working just as easily with Ubuntu.
The other thing i forgot to mention is you have to have all of the
required packages installed before you can compile Xen. I think you are
just missing a bunch of dependent packages. The packages i use and have
installed are as follows:
sudo apt-get install wget tar bzip2 build-essential libncurses5-dev
kernel-package fakeroot bcc gcc ssh bridge-utils python-dev uuid-dev
libglib2.0-dev libyajl-dev libaio-dev gcc-multilib iasl libpci-dev flex
bison qt4-dev-tools patch ocaml-findlib libsdl1.2-dev
Granted some of the above packages are more important for compiling the
kernel.
SO, as long as you have all required packages and follow the
instructions before about getting and compiling Xen 4.2 revision 25392,
it should be fine, no matter if you are using Debian or Ubuntu. Ubuntu
however "might" need more packages, not sure, i have not compiled Xen
under Ubuntu yet.

With revision 25392. Thank you so much for your clear instructions! I
will install wheezy tonight and try the build again.

Well than you probably already have the latest revision. You can also
check what revision your locally cloned repository is at by going to
the
folder and running:
*cd ../xen-unstable.hg
hg summary
*
And that will show you a summary of the local mercurial clone and show
the latest revisions that was cloned.
SO, anyhow, compiling the Xen 4.2-unstable from the mercurial has not
been working very well for a few weeks now. I have asked the Xen-devel
about that a several times and there are issues and problems with
different GCC compilers AND the Xen-devel team knows all that and are
working on fixing that.
For now, the LAST revision i was able to compile and get running was
*"revision 25392*", but even that was possibly ONLY if you remove one
patch. You can try to download and compile THAT version by running the
following commands:
_*Cloning Xen:*_
*- cd /some/directory/in/home
- rev=25392&& hg clone -r $rev
http://xenbits.xen.org/hg/xen-unstable.hg/ xen-unstable.hg-rev-${rev}
- cd xen-unstable.hg-rev-25392
- hg backout -r 25364*
This will clone the xen-unstable.hg mercurial and download Xen
4.2-unstable revision 25392 into the folder
"*xen-unstable.hg-rev-25392*". Running the command "*hg backour -r
25364*" removes or backs out that particular patch. It seems that
without that, even that revision wont compile.
_*Compiling Xen:*_
Than just simply run these commands to compile Xen.
*- cd xen-unstable.hg-rev-25392*
*- ./configure
- sudo make -j5 xen&& sudo make The compile command above just
strings together the 4 compiling commands
to run and will execute one after the other SO you don't have to
manually run each and every one. Also, In the above "*make*" commands,
using the "*-j5*" option after each make tells the compile to use more
than one core to compile with. It speeds up the compili> have a multi-core
CPU. SO in my case, i have a Quad Core CPU, so that
command option is "*-j1 + number of CPU cores*". You can modify or
remove that as you wish.
The above will also create for you a nice DEB package after all the
compiling is done, if you do not want to create a DEB package at the
end
of it all, than just remove the last "*&& sudo make -j5 deb*"
command.
Granted, i am running and doing all of this on Debian Wheezy BUT i
there
aren't any differences in compiling it on Ubuntu 12.04.

I am running ubuntu 12.04, kernel ver: 3.2.0-24-generic
Any ideas? I have googled furiously and found some people talking
about
qemu-kvm having the same issue:
https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/930181
But I was not able to find the patch
Thanks in advance!
