Problem create host in opennebula

i have a probleme to create host in open nebula

Hello!

Do you have access to that hostname?

hostname=vcenter.vcenter3??
no i don’t have access in this name i would create a new host

https://docs.opennebula.org/5.4/deployment/node_installation/vcenter_node_installation.html

“Step 1: Check connectivity
The OpenNebula Front-end needs network connectivity to all the vCenters that it is supposed to manage.”

Try ip address instead of hostname

I do but that’s the same problem
