嘗試安裝 Guest Additions 我看到：
sh ./VBoxLinuxAdditions.run
The headers for the current running kernel were not found. If the following module compilation fails then this could be the reason. The missing package can be probably installed with yum install kernel-devel-2.6.18-194.el5
Building the main Guest Additions module [FAILED]
嘗試安裝 kernel-devel-2.6.18-194.el5 我看到：
yum install kernel-devel-2.6.18-194.el5
Setting up Install Process No package kernel-devel-2.6.18-194.el5 available. Nothing to do
可以用它做什麼呢？
主機作業系統是Windows 7 64位，來賓作業系統是RedHat 5.5 64位。
答案1
嘗試kernel-headers-2.6.18-194.el5。
它在 Debian 上對我有用
通常yum install kernel-headers會自行選擇正確的版本
