# BUILDING vhd-util on Linux
# The xen repository has a tool called vhd-util that compiles and runs on any linux system 
# (http://xenbits.xensource.com/xen-4.0-testing.hg?file/8e8dd38374e9/tools/blktap2/vhd/ or full Xen source at http://www.xen.org/products/xen_source.html).
# Apply this patch: http://lists.xensource.com/archives/cgi-bin/mesg.cgi?a=xen-devel&i=006101cb22f6%242004dd40%24600e97c0%24%40zhuo%40cloudex.cn.
# Build the vhd-util tool:
#    cd tools/blktap2
#    make
#    sudo make install
