安装RHEL6-64时出现如下提示
Anaconda died after receiving signal 7
1 Anaconda是啥
是RedHat、CentOS、Fedora等Linux的安装管理程序

2 网上找到相关的一篇文章，说是虚拟机的内存设置不够（我设置为1G）

对方的提示：Anaconda died after receiving signal 9.19-54.el6.noarch(2MB)
2.1 尝试将虚拟机内存设置为2G
未能解决
3 查关于died after receiving signal 7
查了半天没查清楚
4 突然想到，以前安装linux虚拟机的时候，要使用custom模式，而不是typical模式，而且要在定制好虚拟机后再加载ISO
使用custom模式，定制好虚拟机后再加载光驱，成功进入安装，但是选择安装后依然提示一样的信息。
（之前的设置是typical模式，而且一开始就加载了ISO镜像）
5 查一下signal 7是什么信号
似乎与signal SIGEMT有关
http://linux.about.com/od/commands/l/blcmdl7_signal.htm
SIGEMT is not specified in POSIX 1003.1-2001, but neverthless appears on most other Unices, where its default action is typically to terminate the process with a core dump.
5.1 继续查有关SIGEMT有关的信息
The SIGEMT signal is sent to a process when an emulator trap occurs.
意思是，当“仿真陷阱”发生时，就向处理器发送这个信号
5.2 那么仿真陷阱是啥
Emulator trap; this results from certain unimplemented instructions which might be emulated in software, or the operating system‘s failure to properly emulate them.
似乎是 由当前未生效的指令引起的，这些指令也许在软件仿真失败，或是操作系统无法成功仿真。
6 另一种说法是总线错误

我猜测是由于之前在BIOS中设置CPU支持虚拟化时没有设置完全，即主机虚拟化没有打开。
重启PC，完善一下
