Unable to depoly a vm with the default centos template on xenserver 8.4

Beginne bei CitrixResourceBase.java:1300 und dem Xenserver84Resource-Warnpfad und verfolge dann die Bereitstellung ausgehend von CitrixStartCommandWrapper.java. Reproduziere die Bereitstellung der standardmäßigen CentOS-Vorlage auf XenServer 8.4 und untersuche, wie das Gastbetriebssystem und die Vorlage ausgewählt werden. Die Aufgabe ist erledigt, wenn die unterstützte CentOS-Vorlage erfolgreich bereitgestellt wird, ohne dass der Fehler "Cannot find Template CentOS 7" auftritt.

4. Xenceter 8.4 says Centos 7 is deprecated

What to do about it?

Cloudstack should map the correct guest os in case the host is xenserver 8.4

or go about replacing the templated with a newer version
