Trying to add XCP-NG 8.3 Host to CloudStack 4.20.1.0 - Unable to add the host: Cannot find the server resources at http://xx.xx.xx.xx

Hello, I have upgraded Cloudstack to the latest version, and it is supposedly now supports xcp-ng 8.3, however, either I am doing something wrong or there is some other explanation:

[weizhouapache]

is the hypervisor type of the cluster HyperV or XenServer ?

[fmillah]

Oh silly me, I was too excited, and I selected kvm, what was weird was that even tho kvm was the wrong choice, claoudstack did change the name of the datastores into some weird guid.
I have also experimented with a mix, and it seems like it won't allow me to add a second pool (made of xcp 8.2) to the same cluster.
I was able to add it to a second cluster I created, and it makes sense.
Question about the storage: I did not see an option for fibre channel inside Cloudstack, or does it work like indiorectly, by presenting it to the xcp hosts either from xoa or xcp-ng center?

For everyone trying Cloudstack with XCP-NG 8.3 I can confirm it now works! Hurray!

Thank you!
