xen 和kvm
XEN 只安装了部分，后来夭折了，kvm安装成功！# wget http://bits.xensource.com/oss-xen/release/4.1.3/xen-4.1.3.tar.gz
# tar xvf xen-4.1.3.tar.gz
# cd xen-4.1.3
# make xen tools stubdom
Error: zlib check failed
Make sure to have the zlib libs and headers installed.
make: *** Error 1
make: Leaving directory `/root/xen-4.1.3/tools'
