我尝试创build虚拟机时出现以下错误：

检查kvm模块是否正确加载（可能不是）：
# lsmod | grep kvm
它应该打印像这样的东西：
kvm_intel 121968 0 kvm 287708 1 kvm_intel
如果没有，请检查您是否正确安装了qemu-kvm。 在Ubuntu / Debian上：
# sudo apt-get install qemu-kvm
您也可以尝试手动加载该模块：
# sudo modprobe kvm
另一个常见的问题是，您正试图在没有虚拟化支持的CPU上使用kvm，或者在BIOS中禁用了虚拟化支持（查看您的主板/ CPU文档）。 在Linux上，使用这个命令很容易find它：
# egrep '^flags.*(vmx|svm)' /proc/cpuinfo
最后，我看到你正在使用名为“ttylinux – VMware”的映像，但你正在尝试使用KVM，所以你应该试试这个 。
