Hello, we ran LXD n OpenNebula and downloaded some appliances from the marketplace. Compute nodes use Ubuntu 18.04.2 and ubuntu xenial container is working good. Problem is with:

- centos 7 - no VNC, no ping
- centos6 - no VNC, can ping, can ssh into it

How to debug these problems?

Thank you for the advice!

Could you clarify if the centos images are from the LXD or regular OpenNebula marketplaces ?

Regarding VNC

[http://docs.opennebula.org/5.8/deployment/open\_cloud\_host\_setup/lxd\_driver.html#guest-issues](http://docs.opennebula.org/5.8/deployment/open_cloud_host_setup/lxd_driver.html#guest-issues)

You can update the default VNC command action (login) to have a plain shell

[http://docs.opennebula.org/5.8/deployment/open\_cloud\_host\_setup/lxd\_driver.html#configuration](http://docs.opennebula.org/5.8/deployment/open_cloud_host_setup/lxd_driver.html#configuration)

The image is imported from the Sunstone App menu. It is an LXD image from Linux containers.

VNC is working now, I look on the network config, and looks like there is a problem with contextualization. There is interface eth0@if20 and context script counts with eth0, eth1…

EDIT: On centos 6 is interface named eth0@if22 and contextualization is working…

The `eth0@number` isn’t a problem, context was patched for that when LXD support was implemented.

I’m not able to reproduce the issue. I instantiated the VM template generated by `root@ubuntu1804-lxd-marketplace-abb11-0:~# onemarketapp export 47 'centos7' -d 1`.

Then added 2 NICs

Hello, thank you for the reply. I have still a problem with network contextualization on centos7 and also on ubuntu bionic. Ubuntu xenial and centos6 are working fine.

When I log in via VNC and bash, I can see that the network is not configured at all. Also in /etc/ there is no one-context.d dir, why? I can set up IP and default route manually, and it is working. I also can not edit `/etc/resolv.conf` because of permissions (I am root, the file is owned by uid/gid 65534)

If the images are imported from the marketplace you need to make sure the VM template has LXD\_SECURIRY\_PRIVILEGED set to true.

What version are you using ? I think in 5.8.1 the option wasn’t set by default, not sure.

hi, @feldsam:

Open the Chrome Developer Console (Ctrl+Shift+J) select the tab “Console” and modify the template again. Can you give me a screenshot of what appears is the same?
