Hi,

With reference to this thread 
http://www.gossamer-threads.com/lists/xen/devel/283347, I tried to 
workaround the above-mentioned problem. The following are steps I have 
taken to compile and install Xen 4.3-unstable changeset 26666.

cd
hg clone -r 26666 http://xenbits.xensource.com/xen-unstable.hg 
xen-unstable.hg-cs26666
cd xen-unstable.hg-cs26666
./configure
make world
cd
git clone git://xenbits.xen.org/qemu-xen-unstable.git
cd qemu-xen-unstable
cp -a * 
/home/teo-en-ming/xen-unstable.hg-cs26666/tools/qemu-xen-traditional-dir-remote
cd ..
cd xen-unstable.hg-cs26666
*sudo -s*
./configure
make world
make install

Xen 4.3-unstable changeset 26666 compiles and installs successfully. 
However...

It appears that my Xen 4.3-unstable changeset 26666 installation is 
broken. How do I fix this issue? Are there any mistakes in the steps I 
have taken?

Thank you very much.
