【问题描述】：
我正在尝试在 Redhat 7 VM（在 ESXi 主机上）上运行 virt-install。
我收到错误：
[root@localhost ~]# virt-install
ERROR Host does not support any virtualization options
我知道我需要额外的参数，但同样会失败。
我已经检查了 VM cpu 的“硬件虚拟化”并将“CPU/MMU 虚拟化”设置为硬件和软件都没有帮助。
virt-host-validate 看起来不错：

CPU 有正确的标签 (vmx)：
[root@localhost ~]# grep --color -E "vmx|svm" /proc/cpuinfo

kvm 已加载：
root@localhost ~]# lsmod | grep kvm
kvm_intel 188688 0
kvm 636969 1 kvm_intel
irqbypass 13503 1 kvm
还缺少什么？ （我需要 virt 函数来通过 Lorax livemedia-creator 创建 live-cd，我真的不想为此使用单独的物理机......）
是的，我已经尝试重新安装每个 virt 包。
