[Starlingx-discuss] <Openstack-StarlingX> Unable to run ssh/iperf on StarlingX Vm

[Anirudh Gupta]

Hi Chris

Yes, I ran the command

ethtool --offload eth0 rx off tx off

After that the SSH/Iperf ran successfully.

So, is it a bug that needs to be resolved from StarlingX side?

Because everytime it needs to be run inside the guest VM, which is not practical.

Also I have another query :

I  was trying to create IPV6 network on StarlingX.
When I spawn a VM on that, the IP is visible in Horizon, but I am not getting the IP inside the VM.
I have tried using Centos/Ubuntu VM's.
Even manually enabling the dhcp inside the VM, IP is not being allocated to the interface.

On Ubuntu 16.04, in /etc/network/interfaces file

auto eth0
Iface eth0 inet6 dhcp

But still IPV6 is not automatically allocated to the interface. I need to manually add the IP in it using the command

ip -6 addr add eff0:eff0:eff0::a/128 dev eth0.

Can you please help me in resolving both my issues.

Regards
Anirudh

Anirudh:

Have you tried the workaround mentioned in comment #7 in the bug report ?
Are you able to ssh to localhost (ssh to VM itself from within the VM)

Hi Chris,

I am pinging from one VM to another over graphical console, which is successful. But when I try to run ssh or iperf, then there is no success.
I am using Ubuntu 16.04 Image, which is ssh enabled and yes the service sshd is running.
I have created a flat network as well as vlan network and tried doing ssh/iperf on both, but with no success.
There is no virtual router.

I am suspecting the issue mentioned in the below bug

https://bugs.launchpad.net/starlingx/+bug/1790514<https://ind01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbugs.launchpad.net%2Fstarlingx%2F%2Bbug%2F1790514&data=02%7C01%7C%7Caedb352fcabc43c891e408d6eb50eda6%7Ca65543b9ae9349b580f00b85821adc50%7C1%7C0%7C636955130182595558&sdata=tv%2FD95%2Bvaj4oFWtyGbVDDsL%2BPO%2BaCptl5%2BQVxz5KTB8%3D&reserved=0>

But I have no understanding as why it is happening.

Anirudh, can you provide some details with respect to:

1) How are you pinging from one VM to the other (is it over the graphical console ? or namespace ?)
2) What VM image are you using? - Is the VM image enabled for SSH with password ? (assuming sshd is running)
3) Network topology
4) Are you trying to ssh from one VM to the other or from a different network segment?  Is there a virtual router in the picture, etc..

Hi Team,

I have created All in one simplex setup using release 2018.10.

I have spawned 2 VM’s on it.
The ping is successful between the VM’s, but I am unable to ssh or run iperf on it.

Can you please help me in resolving the issue.
