uname -a显示：

我已经在BIOS上打开了英特尔VT. / proc / cpuinfo文件内容：

当我运行qemu时,输出是：

>./qemu-system-x86_64 -smp 1 -m 1024 -enable-kvm -vnc :1 -usb -usbdevice tablet -hda /opt/nsfocus/sda1/win2008r2.qcow2
Could not access KVM kernel module: No such file or directory
failed to initialize KVM: No such file or directory

我已经尝试将kvm和kvm-intel编译成内核而不是内核模块,结果是一样的.

解决方法:

尝试手动添加：

mknod /dev/kvm c 10 232
