我正在尝试从以下位置构建虚拟交换机的声波构建映像https://github.com/Azure/sonic-buildimage在 ubuntu 16.04/xenial vm 上使用 vagrant，但出现错误：
++ on_error
++ echo '============= kvm_log =============='
============= kvm_log ==============
++ cat /tmp/tmp.3CIfxaYzCK
Could not access KVM kernel module: No such file or directory
qemu-system-x86_64: failed to initialize KVM: No such file or directory
+ on_exit
+ rm -f /tmp/tmp.3CIfxaYzCK

我已完成构建指南中提到的所有先决条件，并且我正在使用 202006 发布分支。
我之前做过一些研究，我认为 kvm 可能存在一些问题。但是当我sudo modprobe kvm-intel在 vm 上尝试时，它显示：modprobe: ERROR: could not insert 'kvm_intel': Operation not supported
结果来自dmesg | grep kvm：
