Hi,

i have same issue when adding XCP-ng 8.3 host to CloudStack 4.19.1.3 (pool with single host):

cloudstack log:

2024-11-28 15:24:31,812 INFO  [c.c.r.ResourceManagerImpl] (qtp660017404-16:ctx-2963461b ctx-f5077d60) (logid:c31fbed3) Trying to add a new host at http://10.1.253.118 in data

i've API call packet capture an i found that 'pool.get_record' section 'restrictions' has only one ocurence of 'restrict_vtpm'
but 'host.get_all_records' section 'license_params' has 'restrict_vtpm' twice, same as 'xe host-license-view' output.
