XenServer can't provisionong instance

Dears,

I have 2 XenServer env, version 7.2 and 8.2 added into Morpheus, then create a new SR (NFS ISO), now I want to create an instance but got failed, the log as below:

2023-06-09_07:49:57.70890 , cloudConfigFile:morpheus_server_514.iso]

but I create a CIFS server on Ubuntu 20.04 and let XenServer 8.2 mounted, it can provision instance and will see the iso upload to the CIFS, but in XenServer 7.2, the CIFS will mount fail.

How can I config the XenServer 7.2 and let it provision instance?
