仅无法 ping 通 Windows 客户机。可以 ping 通其他客户机。
主机操作系统 Ubuntu 18.4.2
我目前所做的-尝试将设备更改为 virtio、rtl8329、e1000
互联网正在为访客提供服务。
Windows 7 客户防火墙已禁用。
从以下位置安装了适用于 Windows 的 virtio 驱动程序 -https://launchpad.net/kvm-guest-drivers-windows/+download
https://ubuntuforums.org/showthread.php?t=2308987
从能够 ping 到同一网络和主机中的 centos 客户机的主机。
这是主机的网络配置。

谢谢你们，这个问题我已经解决了。
Windows 7 阻止了 ICMP 流量，奇怪的是我禁用了防火墙和服务但没有运气。;)
在我启用防火墙规则以允许 icmp 数据包后，它就起作用了。
