fedora opensuse 都不能正常安装 ubuntu就没问题，而mandriva可以用源里的。
今日在fedora15又尝试了一番，最后终于成功。理论上来说，只需要安装kernel-devel, dkms, gcc，但发现内核是RC，并不匹配，所以需要升级内核，而内核是PAE（PAE即物理地址扩展，允许在32位系统使用最大64GB内存），所以还需要的是kernel-PAE-devel，而dkms不装试过也可以启动。
我先做个总结：
1、升级内核：yum update kernel
2、安装必要支持：yum install dkms kernel-PAE-devel qt qt-x11 gcc
3、最后安装：rpm -ivh VirtualBox-4.0-4.0.8_71778_fedora15-1.i686.rpm
有人指出要添加用户到组，我试过没有必要，或者因每个人机器不同而有所差别。
以下是折腾过程，如若发现有哪一步是不需要的，欢迎指出。
首先下载好官方的RPM包。
http://dlc.sun.com.edgesuite.net/virtualbox/4.0.8/VirtualBox-4.0-4.0.8_71778_fedora15-1.i686.rpm
升级内核：fedora15正式版的内核为：kernel-PAE-2.6.38.6-26.rc1.fc15.i686? 当初我还以为我下错版，不过我们可以升级。
yum update kernel 升级到kernel-PAE-2.6.38.6-27.fc15.i686
升级完成后重启电脑
[linuxsight@linuxsight ~]$?uname -r
2.6.38.6-27.fc15.i686.PAE
发现内核已经更新了，但我们还留下一个旧的内核，把它删除。
