      - Flex = Flex
      - .* = LCL

What is the problem?

This is the vCenter infrastructure:

Datacenters:

• Flex
• LCL

Flex DC has:

• int-esx025 (host)
• int-esx026 (host)

LCL DC contains:

• int-lcl-esx001 (host)
• int_lcl_r17_intvc006_clus002 (cluster)

add hypothetical cluster: failed to add vmware hypothetical cluster Cluster{Name: int-esx026, Type: ClusterType{Name: VMware ESXi}}: unexpected status code: 400: {"scope":["1 devices are assigned as hosts for this cluster but are not in site LCL"]}

Steps to reproduce

/

What did you expect to happen?

It uses the mapping from the configuration to map the host and hypothetical cluster to the "Flex" site, instead of LCL

What actually happened?

It wants to map the hypothetical cluster to site LCL
