检查 kvm 模块是否正确加载（可能没有）：
# lsmod | grep kvm
它应该打印类似这样的内容：
kvm_intel 121968 0
kvm 287708 1 kvm_intel
如果没有，请检查您是否已正确安装 qemu-kvm。在 Ubuntu/Debian 上：
# sudo apt-get install qemu-kvm
您还可以尝试使用以下命令手动加载该模块：
# sudo modprobe kvm
另一个常见问题是，您尝试在不支持虚拟化的 CPU 或 BIOS 禁用虚拟化支持的主机上使用 kvm（请检查主板/CPU 文档）。在 Linux 上，只需此命令：
# egrep '^flags.*(vmx|svm)' /proc/cpuinfo
最后，我看到您正在使用一个名为“ttylinux - VMware”的图像，但您正在尝试使用 KVM，因此您应该尝试使用这个。
