Open Stack

Hi,

I have a multinode openstack juno setup. Iperf does not work between 
VMs( on the same compute node asw ell as different compute nodes)

On iperf server VM

|   iperf-s
     ------------------------------------------------------------
     Server  listening on TCP port5001
     TCP window size:  85.3  KByte  (default)
     ------------------------------------------------------------|

On iperf client VM

|  iperf-c192.168.1.42  -p8042  -i1  -t10|

The mtu of the VM interface is 1400. It does not work even after 
increasing or decreasing this value.

|ifconfig
eth0Link  encap:Ethernet   HWaddr  fa:16:3e:ac:70:99   
           inet addr:192.168.1.41   Bcast:192.168.1.255   Mask:255.255.255.0
           inet6 addr:  fe80::f816:3eff:feac:7099/64  Scope:Link
           UP BROADCAST RUNNING MULTICAST  MTU:1400   Metric:1
           RX packets:5781941  errors:0  dropped:0  overruns:0  frame:0
           TX packets:7096888  errors:0  dropped:0  overruns:0  carrier:0
           collisions:0  txqueuelen:1000  
           RX bytes:3028179379  (3.0  GB)   TX bytes:3594331790  (3.5  GB)|

Please help me solve this issue.

Thanks,

Priyanka
