qemu：通过ISO安装ubuntu卡住，显示“ SVM” CPU位警告]] << [

Question

我正在尝试使用以下命令在我创建的qcow2映像之一中安装ubuntu

sudo qemu-system-x86_64 -enable-kvm -nographic -smp 8 -m 8G -cpu qemu64 -cdrom ubuntu-19.10-live-server-amd64.iso -boot d ubuntu-19.10-live-server-amd64.qcow2

首先发出警告，然后挂起

qemu-system-x86_64: warning: host doesn't support requested feature: CPUID.80000001H:ECX.svm [bit 2]
qemu-system-x86_64: warning: host doesn't support requested feature: CPUID.80000001H:ECX.svm [bit 2]

我进行了很多搜索，找到了许多解决方案和可能的问题，但没有一个起作用。

1）也尝试过使用Ubuntu 20，但存在相同的错误。

2）VT-x未启用。

已启用，显示lscpu

Virtualization:                  VT-x
Hypervisor vendor:               KVM
Flags: .. vmx ..

3）尝试-cpu qemu64。没用

4）使用qemu-system-i386代替qemu-system-x86_64。但这失败，并显示另一个错误

This kernel requires an x86-64 CPU, but only detected an i686 CPU.
Unable to boot - please use a kernel appropriate for your CPU.

5）我确实发现“ SVM” CPU位对应于“ AMD Secure Virtual Machine”，这使我感到困惑，因为我的CPU是Haswell。 

帮助！
