虚拟机 CentOS 不能访问 HTTPS 地址

防火墙和 iptables 都已经停了

[[email protected] ~]# systemctl status firewalld.service 
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:firewalld(1)
[[email protected] ~]# systemctl status iptables.service 
● iptables.service - IPv4 firewall with iptables
   Loaded: loaded (/usr/lib/systemd/system/iptables.service; disabled; vendor preset: disabled)
   Active: inactive (dead)

总感觉是网络策略的问题, 但是对 Linux 不精通, 不知道真正问题出在哪里

由于我是通过 WindowsHyper-v 虚拟机装的 CentOS8, 使用的是默认虚拟交换机(Default Switch), 不能访问 HTTPS, 具体原因我也不清楚....

(临时)解决办法

就是创建一个新的虚拟交换机(内部), 并共享网络给他, 虚拟机使用这个网络.
