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?

i also have slow speeds. Checked network connections works perfect. Checked disk performance is really good. But on migration speed is around 25mb/s.

@AtaxyaNetwork
thanks! i suppose this was the issue...

I am trying to migrate from one host to another a vm with a big disk (1.4tb).
Both host on latest version of 8.3.
Transfer is on 1g network with takes many hours.
After many hours there is no task on going and when i searched on logs i found this

tried second time and again the same error.
task has been destroyed before completion.
What can i check to pinpoint the issue?
Thanks in advance

@AtaxyaNetwork

thank you.!
you 've just saved my day!

@amosgiture
xcp-ng 8.2 and 8.2.1 is working without any issue.
Have you checked the logs?
it is recognized as xenserver 8.2.1

@amosgiture
check the cloudstack logs
tail -f /var/log/cloudstack/management/management-server.log
there will be there more info about the issue.

always checking logs help pinpoint the issue.

i have many deployments with cs and 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
