Trying to enable v2v and difficulty adding nbdinfo on xo 6

edsilber

Hoping that other people are having the same issue
Updated one of my test environments to XO6. I wet to test the V2v process and am stuck at the first step on adding nbdinfo.

I don't remember my exact sequence in Events. But in troubleshooting I worked manually installing libnbd.
That at least gave me results when I used the web interface that my version of nddingo was 1.6.1 when It expected 1.23.4
Web searches recommended adding a backport repo. But I thought that generally speaking XOA environment is supposed to be mostly an appliance and we shouldn't be messing with the underlying operating system.

Is anyone else seeing something similar?
I'm on Current version: 6.2.2 - XOA build: 20240311

This is from a fresh install of XO from sources...

this should have walked you through the process to import from vmware.

@acebmxer Sadly the appliance install attempt fails.

Looking at logs there's a broken dependency somewhere.
I just wanted to know if other people are seeing the same thing in the appliance or if it's something in my environment that needs to be repaired.

Yeah I am not sure. I havent seen heard anyone else having similar issues. I heard of other issues in regards to the actual migration but not the setup.

Now that you have logs posted maybe someone form Vates will chime in.

I just tried with my install and i get stuck on first step... Not sure if because of my script or there is an actual issue...

Edit - Just booted up XOA on home lab. It looks like i had attempted to setup previously so can test there. Work XOA again was already setup prior for actual migration. See what other say.

@acebmxer Here's the broken dependency. I'll give the forums a day or so and submit at ticket. Thank you for testing and responding.

you have held broken packages

Have you tried running yum clean and then retrying the install process?

You are running XO from sources, correct? What OS version?

Edit:

Oh, I see you are running a very old deployment of XOA. Deploy a new instance of the appliance and then the package issues will be resolved.

acebmxer

Found issue in my script all seems to be working now for me just no vmware vm to test import on

CGB

Hi, I have the same problem. Everything is installed but still the error for importing VM from VMware. I've updated my XOv5 to the last version but i'm still blocked.

olivierlambert

Hi,

Can you be more specific on the error you have?

acebmxer

@CGB
Are you using XOA or XO from sources? If from sources, who's script did you use to deploy? Also if from source what commit are you on?

edsilber

@CGB Just refreshing XOA and the console didn't do it. I had to redeploy the XO appliance. Newer debian and binaries. export your config.toml and follow the steps like you are deploying a new xoa

CGB

@olivierlambert It looks like I cant' use the VM from VMware option because it can't see that the dependencies are already installed.

@acebmxer I use XO from sources on Debian 12.

@edsilber I will try something before, and if it doesn't work, I'll do what you say. Thank you

pierrebrunet

@CGB Hi, are you running XO from source with root or another user?
If it is another user, it may be not accessible from it

That is what i was able to determine what is going on with my script. - https://xcp-ng.org/forum/post/105965

when using root user button works just fine. If using non-root user the button will never work as it assumes root will use it. I am not sure how other scripts handle this issue.

CGB

Hi, everyone

Thank you for your help.

I had a flux that was blocked by our firewall. The button worked after that.

But it doesn't explain why I lost this configuration and had to reinstall it.

Thanks again.
