Open Stack

Hi,

Have you defined the port in the security groups associated with the VMs?

Subject: [Openstack] iperf not working between VMs


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 port 5001

    TCP window size: 85.3 KByte (default)

    ------------------------------------------------------------

On iperf client VM

 iperf -c 192.168.1.42 -p 8042 -i 1 -t 10

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

ifconfig

eth0      Link 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
