i installed several 6.4 server with openvswitch module and openvswitch
utility from following repo:
http://rdo.fedorapeople.org/openstack/openstack-grizzly/epel-6/
all server have same problem:
network input performance ok and very bad output performance. only
tcp, udp is ok.
we test with scp, wget, iperf and some utility, only get less than 10
KB/s output from the server with openvswitch module.
here is our config:
#ovs-vsctl show
9be7b1dc-35d0-47d2-b383-6816c8bffe01
Bridge "br-eth1"
Port "eth1"
Interface "eth1"
Port "br-eth1"
Interface "br-eth1"
type: internal
Bridge br-int
Port br-int
Interface br-int
type: internal
Bridge "br-eth0"
Port "eth0"
Interface "eth0"
Port "br1000"
tag: 1000
Interface "br1000"
type: internal
Port "br-eth0"
Interface "br-eth0"
type: internal
ovs_version: "1.9.0"
# cat ifcfg-eth0
DEVICE=eth0
HWADDR=00:8C:FA:12:D7:80
BOOTPROTO=none
ONBOOT=yes
DEVICETYPE=ovs
TYPE=OVSPort
OVS_BRIDGE=br-eth0
# cat ifcfg-br-eth0
DEVICE=br-eth0
BOOTPROTO=none
ONBOOT=yes
DEVICETYPE=ovs
TYPE=OVSBridge
cat ifcfg-br1000
DEVICE=br1000
ONBOOT=yes
DEVICETYPE=ovs
TYPE=OVSIntPort
IPADDR=172.16.0.9
NETMASK=255.255.255.0
GATEWAY=172.16.0.1
OVS_BRIDGE=br-eth0
OVS_OPTIONS="tag=1000"
we then compile and install a kmod from git source of openvswitch:
rpm -i --force --nodeps kmod-openvswitch-1.9.2-1.el6.x86_64.rpm
all is OK now.
we should install it with a option "--nodeps", otherwise we have the
following problem:
rpm -i kmod-openvswitch-1.9.2-1.el6.x86_64.rpm
error: Failed dependencies:
ksym(nla_put) = 0x37587aff is needed by kmod-openvswitch-1.9.2-1.el6.x86_64
