Answer 1

检查 kvm 模块是否正确加载（可能不是）：

# lsmod | grep kvm

它应该打印如下内容：

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

您还可以尝试手动加载该模块：

# sudo modprobe kvm

另一个常见问题是，您尝试在 CPU 没有虚拟化支持或 BIOS 禁用虚拟化支持的主机上使用 kvm（检查您的主板/CPU 文档）。在 Linux 上，只需使用以下命令即可轻松查找：

# egrep '^flags.*(vmx|svm)' /proc/cpuinfo

最后，我看到您正在使用名为“ttylinux - VMware”的映像，但您正在尝试使用 KVM，因此您可能应该尝试使用此映像。
