從一個虛擬機到另一個虛擬機的JBoss DataGrid udp複製

Question

在Windows 10主機上有兩個運行openSUSE的VirtualBox，每個運行着一個JBoss DataGrid。 iptables規則在兩個VM上都在系統範圍內禁用。 VM的網絡適配器都配置爲Bridged Adapters。

當第二個實例啓動時，首先觀察它併成爲主人。第二個成爲奴隸。

有如下每個數據網格配置分佈式緩存：

<cache-container name="clustered" default-cache="oaas-properties-cache" statistics="true"> 
       <transport stack="udp" cluster="oaas-cluster" lock-timeout="60000"/> 
       <distributed-cache name="code-error-message-cache" mode="ASYNC" batching="false"> 
        <eviction strategy="LIRS" max-entries="10000"/> 
        <expiration max-idle="${oaas.maxidle.lifespan:87400000}" lifespan="${oaas.properties.lifespan:86400000}"/> 
       </distributed-cache> 
</cache-container> 

套接字綁定還配置：

<socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:5}"> 
     <socket-binding name="management-native" interface="management" port="${jboss.management.native.port:9999}"/> 
     <socket-binding name="management-http" interface="management" port="${jboss.management.http.port:9990}"/> 
     <socket-binding name="management-https" interface="management" port="${jboss.management.https.port:9443}"/> 
     <socket-binding name="ajp" port="8009"/> 
     <socket-binding name="hotrod" interface="management" port="11222"/> 
     <socket-binding name="http" port="8080"/> 
     <socket-binding name="https" port="8443"/> 
     <socket-binding name="jgroups-mping" port="0" multicast-address="${jboss.default.multicast.address:234.99.54.14}" multicast-port="45700"/> 
     <socket-binding name="jgroups-tcp" port="7600"/> 
     <socket-binding name="jgroups-tcp-fd" port="57600"/> 
     <socket-binding name="jgroups-udp" port="55200" multicast-address="${jboss.default.multicast.address:234.99.54.14}" multicast-port="45688"/> 
     <socket-binding name="jgroups-udp-fd" port="54200"/> 
     <socket-binding name="memcached" interface="management" port="11211"/> 
     <socket-binding name="modcluster" port="0" multicast-address="<A_REAL_IP_HOES_HERE>" multicast-port="23364"/> 
     <socket-binding name="remoting" port="4447"/> 
     <socket-binding name="txn-recovery-environment" port="4712"/> 
     <socket-binding name="txn-status-manager" port="4713"/> 
    </socket-binding-group> 

據對兩個VM UDP包從一個去Wireshark的一邊到另一邊，反之亦然。但我看不到這些軟件包在wireshark中通過主機（奇怪，是不是？）。

最後，檢查DataGrid的其餘接口我注意到緩存複製實際上並不工作。把價值主宰，我不能從奴隸獲得它。

最後，因爲從正在運行，主定期記錄此：

10:26:03,839 WARN [org.jgroups.protocols.TP$ProtocolAdapter] (INT-1,shared=udp) JGRP000031: linux-bb91/oaas-cluster: dropping unicast message to wrong destination linux-bb91/oaas-cluster 

和從日誌，這些日誌：

10:26:03,903 WARN [org.jgroups.protocols.UDP] (TransferQueueBundler,shared=udp) JGRP000032: null: no physical address for 4d05dc4d-66ac-1943-4e97-92c6e2b471c0, dropping message 

想不通究竟是什麼錯。這裏有的iperf實用程序（由從到主，反之亦然）的結果：

#iperf -s -u -B $MASTER_IP -i 1

------------------------------------------------------------

[ 3] WARNING: did not receive ack of last datagram after 5 tries. 

但是，當我從主機器Wireshark的發送nc $SLAVE_HOST 45688顯示傳入的包和ACK。

需要幫助。甚至不知道我可以在哪裏挖掘。謝謝。

UPD

UDP封裝現在似乎要兩側。當我在服務器模式下運行iperf3從另一個虛擬機作爲客戶端結果檢查是：

和服務器接收包：

Answer 1

我最後一次看到消息「沒有物理地址因爲「是多年前的事情，而且它變成了網絡接口驅動程序中的一個錯誤，並且與實際有缺陷的硬件相結合。

我從來沒有嘗試在VirtualBox上運行Infinispan：這可能沒有與VirtualBox的驅動程序結合使用進行測試;特別是UDP協議棧非常敏感，通常預計會被高級用戶使用，他們會進入並調整堆棧（更改JGroups配置）。

例如對於UDP協議，ip_ttl對於VirtualBox意味着「橋接」的含義可能不夠高？

您可以嘗試不同的虛擬化或容器策略嗎？
