Linux 和 KVM Qemu VM - 尽管主机和 VM 都桥接且位于同一子网中，但“无法为主机进行 ARP”

我正在 Kali linux 主机中使用 KVM Qemu，并尝试练习 ARP 欺骗。在 Kali Linux（连接到有线以太网）中，我设置了以下配置（来自我遵循的教程），以将/etc/network/interfaces我的 KVM 虚拟机配置为使用桥接网络模式。

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

auto br0
iface br0 inet static
        address 192.168.10.12
        broadcast 192.168.10.255
        netmask 255.255.255.0
        gateway 192.168.10.1
        bridge_ports eth0
        bridge_stp off
        bridge_waitport 0
        bridge fd 0

ip a为了提供更多信息，以下是在我的主机上运行的结果：

现在，在创建 KVM 虚拟机时，我将其设置为使用桥接网络模式，如以下屏幕截图所示。

192.168.10.301然后在虚拟机内部，我通过在文件中执行以下配置为其提供静态 IP /etc/network/interfaces：

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

#The primary network interface
allow-hotplug enp1s0
iface enp1s0 inet static 
    address 192.168.10.30
    netmask 255.255.255.0
    gateway 192.168.10.1

主机和虚拟机都能互相ping通。但是，当我尝试arpspoof通过sudo arpspoof -i eth0 -t 192.168.10.30 192.168.10.1在主机上执行来运行时，我得到了arpspoof: couldn't arp for host 192.168.10.30. 问题是为什么以及我该如何解决它？

我尝试过的：

当然，我在发帖之前尝试搜索它，我发现了大量的结果，包括这个论坛上的结果，但它们是针对 VMWare 或 Virtual Box 的，OP 要么尝试跨不同的子网，要么不会采用桥接模式网络等。我负责所有这些事情。
