我有一臺RHEL6.4操作系統的主機。在主機下，我有一臺運行RHEL6.4的KVM虛擬機。Openvswitch/KVM訪客無法ping通外部網關
主機被連接到具有VLAN標籤1
我如下配置的主機的網絡接口標記交換機接口：
的ifcfg-eth0的
＃DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
USERCTL=no
BOOTPROTO=none
MASTER=bond0
SLAVE=yes
ifcfg-eth1
＃DEVICE=eth1
TYPE=Ethernet
ONBOOT=yes
USERCTL=no
BOOTPROTO=none
MASTER=bond0
SLAVE=yes
的ifcfg-bond0
＃DEVICE=bond0
TYPE=Bond
BONDING_MASTER=yes
BOOTPROTO=static
NAME=bond0
ONBOOT=yes
USERCTL=no
BONDING_OPTS="mode=active-backup primary=eth0 miimon=100"
和主機的vSwitch如下：
＃ovs-vsctl add-br ovsbr0
ovs-vsctl add-port ovsbr0 bond0
ovs-vsctl add-port ovsbr0 vlan1 tag=1 -- set interface content type=internal
ifconfig vlan1 192.168.1.2/28 up
而且我能ping外部vlan1 GW（192.168.1.1）。
我遇到的問題是我無法從VM ping通外部IPv4網關。 當我從虛擬機ping通時，我得到了第一個數據包的響應，但其他數據似乎失去了VLAN標記並進入錯誤的界面。 如果我和tcpdump bond0.1我看到的第一個ICMP請求和應答，但ICMP回信的其餘部分似乎出現bond0接口（未bond0.1）

的VM的網絡接口被配置爲如下：
的ifcfg-eth0的
＃DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
USERCTL=no
BOOTPROTO=none
MASTER=bond0
SLAVE=yes
的ifcfg-eth1的
＃DEVICE=eth1
TYPE=Ethernet
ONBOOT=yes
USERCTL=no
BOOTPROTO=none
MASTER=bond0
SLAVE=yes
的ifcfg-bond0
＃DEVICE=bond0
TYPE=Bond
BONDING_MASTER=yes
BOOTPROTO=static
NAME=bond1
ONBOOT=yes
USERCTL=no
BONDING_OPTS="mode=active-backup primary=eth0 miimon=100"
的ifcfg-bond0.1
＃VLAN=yes
TYPE=Vlan
DEVICE=bond0.1
NAME=bond0.1
BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.1.3
NETMASK=255.255.255.240
任何想法爲什麼會出現此問題？
