So happy for what happened at github

@xcp-ng-justgreat can you make a guide? what have you done and it is working? Will save time and will be really appreciated

@stormi we should inform cloudstack team about the upgrade.....

@kurushi9000 you have added this into database cloud i suppose?
will report to cloudstack team.

@olivierlambert
https://github.com/cert-ee/cuckoo3

you are right.
Seems that they are preparing next version. I don't know what hypervisors will work with this.

Edit: qemu and kvm.

@fohdeesha wow!
thanks for your help! really happy that you belong to xcp-ng pro support team!

@xcp-ng-justgreat Title changed.

Can you help me with the AND and what exactly have you done? Give me an example to understand.

I want to try cuckoo sandbox.
At the documentation of cuckoo it is written that you can use xenserver as the vm platform.
Has anone tried it with xcp-ng?

@stormi said in XCP-ng 8.3 updates announcements and testing:

Indeed, we forgot to tell you about this temporary regression. They're coming back in the next batch of updates, as soon as CI is green!

what is CI ?

came across this topic..
i have exported a vm and trying to import it to another xcp.
I had issues with the migration so i tried export and import
and i have this error

HTTP handler of vm.import

@AlexanderK said in Mirror failed:

"OLD_447ff17a-82bc-4d49-a177-02f9086e9a04

That's the missing bit reported by XAPI/SM, indeed.

Does this mean it is a bug?

i started searching logs.
and i have found at xensource.log something about a uuid that is missing from a db something.

can anyone help me pinpointing the issue and fixing it?
Thanks in advance

@stormi said in XCP-ng 8.3 betas and RCs feedback :

@AlexanderK We don't test it, but they use XAPI and the API doesn't change that much, so it should. We contacted them last april and they said any necessary changes on CloudStack side should be done after the release.

https://github.com/apache/cloudstack/discussions/8964

when there was the update of 8.2.1 there have been many issues...
anyway...i think 8.3 is not an lts... so i will wait and check at a lab enviroments
Thanks for the reply!
