Updated xcp-ng-pv-tools on my one XCP 8.2 server. (We have mostly (citrix)7.1 and (xcp)7.6 because of hardware RAID limitations)
Found the ISO located at /opt/xensource/packages/iso. (verison 8.2.0-9)
Moved this to my local workstation, and then to my ISO-repo file server.
Went to my XCP 7.6 server, and then to the Rocky Linux 8.4 VM i just set up.
Removed the EPEL xe-guest-utilities-latest package. (7.21.0-1)
Mounted the XCP ISO from the ISO-repo and installed the guest tools from that. (7.20.0-9)
Agent detected! and the service seems to run without error.
