好象提示说Cannot execute 32-bit applications! Either enable 32-bit support in the
  kernel configuration or use --disable-vmmraw to disable 32-bit guests.  不支持32位的软件要配置内核，请问要如何配置啊

RichardGv

您既然使用的是multilib的profile，内核中怎会没有开启IA32 Emulation... 还是请您看看您的内核配置中"Executable file formats / Emulations" -> "IA32 Emulation"有没有开启。另外请您贴出emerge --info virtualbox的输出和 /var/tmp/portage/app-emulation/virtualbox-4.1.8/work/VirtualBox-4.1.8_OSE/configure.log 的内容。

另外，请注意如果您没有开virtualbox的qt4 USE flag，它就没有图形界面。

楼主这个问题很好解决啊，只要选上

1. Executable file formats / Emulations  --->
   
2.    [*] IA32 Emulation

复制代码

重新编译内核，再次安装virtualbox就OK了。


我这边问题有点杯具了。
我初装系统的时候选择了non-multilib的profile，纯64位，系统里根本没有32位的头文件和库，vbox没法安装了。

1. [b]build.log:[/b]
   
2. Checking for 32-bit support:
   
3.   Cannot compile 32-bit applications (missing headers and/or libraries)!

复制代码

1. [b]configure.log:[/b]
   
2. ***** Checking 32-bit support *****
   
3. compiling the following source file:
   
4. ....
   
5. ....
   
6. /usr/include/gnu/stubs.h:7:27: fatal error: gnu/stubs-32.h: No such file or directory
   
7. compilation terminated.

复制代码

我的CPU也不支持VT虚拟化，没办法使用KVM，直接就杯具了


Debian里面好像是可以直接安装mulitlib的
apt-get install g++-multilib
apt-get install gcc-multilib

Gentoo中有没有类似的解决办法啊？
难道只能重装系统？？？ 搞一趟太累了。

darrenlee

楼上，用linux32 chroot 个stage3 是否可以?

可以从no-multilib转到multilib，只是需要重新emerge几个包，主要是toolchain包。这里有两份教程：
http://jkroon.blogs.uls.co.za/it ... ultilib-to-multilib
http://www.gentoo-wiki.info/HOWTO_AMD_64#Howto_switch_to_multilib
注意gentoo-wiki.info上的教程老了些，对现在的Gentoo系统可能某些细节要变通一下。

@RichardGv.

his cpu not support vt feature. Is that a disaster?

CPU是T3000，不支持VT，所以无法使用KVM，但是Vbox是可以的，以前在Debian下装过vbox，没有问题，只是虚拟的客户机只能使用单核。

感谢回复，为了稳妥起见和避免以后不可预知的麻烦，还是决定重装系统、选择multilib了。
