Re: [Xen-devel] Xen 4.3 PCI passthrough possible bug

[Mike Neiderhauser <mikeneiderhauser@xxxxxxxxx>]

I followed this site (http://wiki.xenproject.org/wiki/Xen_4.4_RC3_test_instructions).

and then followed (http://wiki.xen.org/wiki/Compiling_Xen_From_Source)

git clone -b 4.4.0-rc3 git://xenbits.xen.org/xen.git

Had to take some additional steps here to get all of the libs
# apt-get install build-essential 
# apt-get install bcc bin86 gawk bridge-utils iproute libcurl3 libcurl4-openssl-dev bzip2 module-init-tools transfig tgif 
# apt-get install texinfo texlive-latex-base texlive-latex-recommended texlive-fonts-extra texlive-fonts-recommended pciutils-dev mercurial
# apt-get install make gcc libc6-dev zlib1g-dev python python-dev python-twisted libncurses5-dev patch libvncserver-dev libsdl-dev libjpeg62-dev
# apt-get install iasl libbz2-dev e2fslibs-dev git-core uuid-dev ocaml ocaml-findlib libx11-dev bison flex xz-utils libyajl-dev
# apt-get install gettext
apt-get install libaio-dev
apt-get install libpixman-1-dev

./configure
make dist
make install

It is for QEMU, but you are right - it should have been part
of QEMU if you got the latest version of Xen-unstable.

You didn't use some specific tag but just 'staging' ?
