KVM image but not Openstack: network config fails

7. Troubleshooting Troubleshooting
1

Hi All,

I trying KVM (not Openstack/KVM) image on Prpoxmox which is KVM + LXC virtual environment.

Image is freesbc_kvm_3.0.107.3_172_233929.qcow2.tar.gz

It runs up to the network device roles and fails on try to apply change on network.

Meanwhile, if I create exactly the same VM and install FreeSBC from “baremetal” ISO (freesbc_centos7_x86_64_3.0.107.3.170_233929.iso) it works!

I did some research to ensure that network config completely identical for the both case. It is!

In fact, there no network config at all. By default only ifcfg-lo config file created.

Tracks are adentical:

  1. Deploy/install
  2. No DHCP, go to the console and run “ip addr add {addr} dev eth0”
  3. Go to http://{addr}:12358/
  4. Go through setup process until network devices roles
  5. Devs are visible, all marked as “SBC compatible”.
  6. Assign roles, no dedicated CPU, check, confirm
  7. Success and reboot for ISO image. Error message for KVM image.

Very strange behaviour!

I can supply some extra/log data if you point me where to find it.

Hi

Would you send us your Proxmox Virtual machine settings for FreeSBC please?

While I was trying to find whi it sticks I come to the situation when it fais on iso omage installiation too.

It looks like is better to go into logfiles. Where they are? Wink

Thanks for sharing the Proxmox details. Would you change network type to e1000 please and try again.

I have changed network adaptor type and reattached image for full cleaness.

The result the same: “Failed to configure network devices roles. Please contact support team.”

Would you contact support@telcobridges.com, please?

Please use tbchangeip command to give management IP address if you don’t have DHCP in your network. Don’t run “ip addr add {addr} dev eth0”.

The trouble was incorrect Proxmox VM setup.

Occasionally, VCPUs=1 was set. Thanks to Serdar from support, we found and reproduces that if VCPUs=1 parameter is set to 1 - installiation fails that place. If it’s default value - everything runs ok for both ISO install and KVM image.

DHCP was finally used, but gues it does not matter.
