我正在嘗試建立位於同一虛擬機器管理程式上的 2 個虛擬機器的配置，透過編輯每個虛擬機器的 XML 文件，將虛擬機器管理程式中的 virtIO 介面附加到每個虛擬機器。我創建了虛擬機，並在附件後獲得了這些介面：
ens7: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 11.198.133.5 netmask 255.0.0.0 broadcast 11.255.255.255
ether 00:00:11:22:33:40 txqueuelen 1000 (Ethernet)
RX packets 147 bytes 13980 (13.6 KiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 240 bytes 17952 (17.5 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
ens7: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 11.198.133.6 netmask 255.0.0.0 broadcast 11.255.255.255
ether 00:00:11:22:33:41 txqueuelen 1000 (Ethernet)
RX packets 57 bytes 8360 (8.1 KiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 261 bytes 18666 (18.2 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
每個虛擬機器的每個介面當我透過 IP 從一個虛擬機器 ping 到另一個虛擬機器時，我收到訊息：目標主機無法訪問，但在一個虛擬機器中 ping 並運行時tcpdump-nei ens7 另一方面，我收到訊息：
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

為什麼 tcpdump 識別封包時 ping 指令不起作用？我以分配大頁的方式編輯了 XML，並且 ovs 我們在虛擬機器管理程式上進行了正確的處理。
