fuel 6.1自动推送3控高可用centos 6.5 juno环境排错（二）
https://docs.mirantis.com/openstack/fuel/fuel-6.1/
由于在测试高可用时，我是用esxi虚拟机测试，测试过程中遇到了网络问题：虚拟机间网络不通，故从网络上找到了在vSwitch中抓包的方法。
1、首先先打开ESXi主机的ssh。
2、ssh连接ESXi主机，上传脚本a.sh，此脚本是老外编写 ：
---------------------------------------------------------------------------------------
# William Lam
# http://www.virtuallyghetto.com/
if [[ $# -ne 1 ]] && [[ $# -ne 4 ]]; then
echo -e "Usage: $0 -l -v [vSWITCH] -p [PORT]\n"
echo " -l List all ports of vSwitch(s)"
echo " -v vSwitch to query"
echo " -p Port to query on vSwitch"
echo -e "\n\t$0 -l"
echo -e "\t$0 -v vSwitch0 -p 1234\n"
exit 0
fi
if [ ! -e /sbin/vsish ]; then
echo "Script is only supported running on an ESXi host as vsish is not available by default on ESX"
exit 1
fi
VSISH_VSWITCH_PATH=/net/portsets
if [ $# -eq 1 ]; then
for vSwitch in $(vsish -e ls ${VSISH_VSWITCH_PATH});
do
VSWITCH=$(echo ${vSwitch} | sed 's/\///g')
for port in $(vsish -e ls ${VSISH_VSWITCH_PATH}/${vSwitch}ports);
do
PORT=$(echo ${port} | sed 's/\///g')
PORTINFO=$(vsish -e get ${VSISH_VSWITCH_PATH}/${vSwitch}ports/${port}status | sed 's/^[ \t]*//;s/[ \t]*$//');
CLIENT=$(echo ${PORTINFO} | sed 's/ /\n/g' | grep "clientName:" | awk -F ":" '{print $2}')
MACADDRESS=$(echo ${PORTINFO} | sed 's/ /\n/g' | grep "unicastAddr:" | uniq | sed 's/unicastAddr://;s/\(.*\)./\1/')
echo -e "${VSWITCH}\t${PORT}\t${MACADDRESS%%::*}\t${CLIENT}"
done
done
fi
if [ $# -eq 4 ]; then
QUERY_PATH="${VSISH_VSWITCH_PATH}/${2}/ports/${4}/status"
echo "Querying port path: ${QUERY_PATH}"
PNICS=$(vsish -e ls /net/portsets/${2}/uplinks/ | sed '$!N;s/\n/ /;s/\///g')
echo -e "pNICS for vSwitch: ${PNICS}\n"
vsish -e get "${QUERY_PATH}"
fi
---------------------------------------------------------------------------------------
3、使用脚本查看虚拟机网卡连接的虚拟交换机端口：

4、监听指定端口抓包：
/vmfs/volumes/55b08c38-81076980-4852-f80f41f72abc/ISO # pktcap-uw --switchport 67109199 -o ctrl1.pcap
5、下载数据包，用wireshark分析。
其它推荐学习资料：

我的openstack节点的网络规划是：
则“物理网卡”eth1需要在ESXi中使用VGT配置：
此外，基于ns_IPaddr2的实现机制：命名空间桥接虚拟网桥，需要启用端口组的混杂模式，否则VIP无法被其它节点ping通：
最后，端口组所在虚拟交换机也要开启混杂模式。
