XenServer6.5でxenbrのRX droppedが増え続ける場合の対処方法

Last updated at Posted at 2015-06-30

XenServer6.5のインストール後にifconfigしてみるとRX droppedがカウントされ続けていました。

# ifconfig
xenbr0    Link encap:Ethernet  HWaddr <my macaddress>  
          UP BROADCAST RUNNING  MTU:1500  Metric:1
          RX packets:171 errors:0 dropped:171 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:17121 (16.7 KiB)  TX bytes:0 (0.0 b)

xenbr1    Link encap:Ethernet  HWaddr <macaddress>  
          inet addr:<my inet addr>  Bcast:<my Bcast>  Mask:<my Mask>
          UP BROADCAST RUNNING  MTU:1500  Metric:1
          RX packets:2678 errors:0 dropped:181 overruns:0 frame:0
          TX packets:3807 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:223114 (217.8 KiB)  TX bytes:10707630 (10.2 MiB)

ethtoolでnicのオフロード関係をOFFにしてもダメでしたが、デフォルトのopenvswitchをlinuxbridgeに変更する事でとりあえず解決しました。

# xe-switch-network-backend bridge

変更後は再起動が必要

# reboot

※使ってるスイッチの確認

more /etc/xensource/network.conf

※元のopenvswitchに戻す場合は以下を実行

# xe-switch-network-backend openvswitch

Open vSwitchを使いたいのですが、根本的な解決がされるまではOpenFlowのテストは控えます。
