我安装了两个内核，3.5.0 和 3.6.0。由于多种原因，我必须运行内核 3.5.0。 VirtualBox 在 3.6.0 上完美运行，但在 3.5.0 上不行。
启动内核 3.5.0 后，我触发了 with 的模块重建apt-get --reinstall install virtualbox-dkms。这样就成功地重新编译了 VirtualBox 模块。但是，它无法加载。
# modprobe vboxdrv
ERROR: could not insert 'vboxdrv': Exec format error
/var/log/messages:
warning: `VirtualBox' uses 32-bit capabilities (legacy support in use)
vboxdrv: disagrees about version of symbol module_layout
该模块似乎已正确安装：
$ ls /lib/modules/3.5.0/updates/dkms/
vboxdrv.ko vboxnetadp.ko vboxnetflt.ko vboxpci.ko
系统信息：Debian不稳定，软件包virtualbox-dkms已安装
$ uname -r
3.5.0
$ apt-cache show virtualbox | grep Version
Version: 4.1.18-dfsg-1.1
$ apt-cache show dkms | grep Version
Version: 2.2.0.3-1.2
这是模块构建的输出：

如何让 VirtualBox 在 3.5.0 上运行？
答案1
感谢术士的链接，我认为存在一些版本不匹配。我认为这是由于我没有创建kernel-source包造成的。相反，我使用了 git 存储库，该存储库也用于编译其他几个版本。
首先，我删除了软件包linux-image和linux-headers
（当前正在运行的内核）。
下一步是完全干净的签出（目录中不保留构建）。然后我构建了内核并创建了 packges
linux-image和linux-headers包linux-source并安装了它们。此后，VirtualBox 模块已构建并且加载成功。
我不知道之前哪些版本不匹配，但是遵循这些步骤可以保证不会出现版本不匹配的情况。
答案2
你安装了这个包吗virtualbox-dkms？
我通常必须在每次内核升级后重新安装它，我认为这表明它的 dkms 部分已损坏，但重新安装它对我有用。除了新内核之外，我从未尝试过将其重新安装到任何其他内核上，但我认为它应该针对当前正在运行的任何内核进行构建。
