Categorize the issue, e.g. API, VR, VPN, UI, etc.
-->
~~~
CKS
~~~
##### CLOUDSTACK VERSION
<!--
New line separated list of affected versions, commit ID for issues on master branch.

Advanced networking
##### OS / ENVIRONMENT
<!--
Information about the environment if relevant, N/A otherwise
-->
CentOS7 on MS, XCP-NG 8.2 on hypervisors
##### SUMMARY
<!-- Explain the problem/feature briefly -->
Cannot create kubernetes cluster from classic/primate UIs. It fails on master VM creation. Other Linux/Winsows VMs are created by MS without issues on the same hypervisor.
##### STEPS TO REPRODUCE
<!--
For bugs, show exactly how to reproduce the problem, using a minimal test-case. Use Screenshots if accurate.
For new features, show how the feature would be used.
-->
<!-- Paste example playbooks or commands between quotes below -->
~~~
1. Enable the kubernetes service
2. Register new kubernetes version:
add kubernetessupportedversion name=v1.16.3 semanticversion=1.16.3 url=http://packages.shapeblue.com.s3-eu-west-1.amazonaws.com/cks/setup-1.16.3.iso mincpunumber=2 minmemory=2048
3. Add CoreOS template from http://dl.openvm.eu/cloudstack/coreos/x86_64/coreos_production_cloudstack_image-xen.vhd.bz2
4. Wait till its ready
5. Now create a kubernetes cluster from UI with 2 nodes
~~~
<!-- You can also paste gist.github.com links for larger files -->
##### EXPECTED RESULTS
<!-- What did you expect to happen when running the steps above? -->
~~~
Expected kubernetes cluster to be created successfully
~~~
##### ACTUAL RESULTS

It seems that correct template is used. This is nfs mount from MS host:

@sm97 Couple of things,
- Have you tried it with a different hypervisor? XCP-NG 8.2 support is not present in 4.14 and not even in master. Did you add all OS mappings? Though at this point I'm not sure if that's all we will need for XCP-ng 8.2.
- Does the deployment of VMs outside CKS plugin work fine with CoreOS template?

Hypervisor must be coming as null here. Will check code for more. Till then, ca you please check/answer,
- While adding XCP-ng 8.2 hosts did you add guest OS mappings for XCP-ng 8.2.0 version?
- Please share cloudmonkey response for your CoreOS template
- To reproduce this, MS is CentOS 7, hosts XCP-ng 8.2, advance networking zone?

@shwstppr Thanks for prompt reply,
* No, I have no extra server to test different hypervisor. Test stand is in my plans, but not nearest one :( I know that XCP-NG 8.2 is not listed in supported ACS configurations, but it does works well for me for regular usage.
* I have tested CoreOS template outside of CKS plugin and it runs well. But CKS just fails to create new VMs. That's the root cause of my issue.
What else I can gather for you?

@sm97 can you please try deploying k8s cluster after setting `vm.instancename.flag` to false.
Issue here doesn't seem to be with CKS itself, the code in UserVmManagerImpl.java seems to be checking the wrong variable for hypervisor type at line 3764
https://github.com/apache/cloudstack/blob/6f96b3b2b391a9b7d085f76bcafa3989d9832b4e/server/src/main/java/com/cloud/vm/UserVmManagerImpl.java#L3764
I'll add a fix for this.

@sm97 4.14 didn't have XCP-ng 8.1+ support officially. I couldn't see 8.2 released on XCP-ng site. With guest os mappings I meant something like, https://github.com/apache/cloudstack/pull/4068/commits/b9edc955ed0a83fbb3bbc5a060cffe87d448dab0#diff-1ce878cd8ce12c2ca2fbe9c3639af33eR28-R32
I've tried to reproduce this locally but couldn't see NPE, will try to dig further.
Template seems okay. Can you please verify cluster was using same template for deployment (by checking cluster VMs).
