xen的最新版是4.2.1版，但是我編譯後xen內核引導到一半就退出，而fedora的yum安裝的就是4.1.4版。不解
安裝依賴項：
$yum groupinstall "DevelopmentLibraries"
$yum groupinstall "DevelopmentTools"
$yum install transfig wget tar lesstexi2html libaio-devel dev86 glibc-devel e2fsprogs-devel gitk mkinitrd iaslxz-devel bzip2-devel
$yum install pciutils-libs pciutils-develSDL-devel libX11-devel gtk2-devel bridge-utils PyXML qemu-common qemu-imgmercurial texinfo
$yum install libidn-devel yajl yajl-develocaml ocaml-findlib ocaml-findlib-devel python-devel uuid-devel libuuid-developenssl-devel
$yum install glibc-devel.i686
然後下載xen-4.1.4，並解壓。查看readme文件，執行make world和make install
接下來，請不要直接修改grub.cfg文件，而是執行命令grub2-mkconfig -o /boot/grub2/grub.cfg
重啓選擇xen，進入後如果你遇到
- ERROR Internal error: Could not obtain handle on privileged command interface (2 = No such file or directory)
- Traceback (most recent call last):
- File "/usr/sbin/xend", line 51, in ?
- from xen.xend.server import SrvDaemon

- xc = xen.lowlevel.xc.xc()
- xen.lowlevel.xc.Error: (1, 'Internal error', 'Could not obtain handle on privileged command interface (2 = No such file or directory)')
你需要換一種方式執行，使用命令/etc/init.d/xend start
