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

Empieza en CitrixResourceBase.java:1300 y en la ruta de advertencia de Xenserver84Resource; después, sigue el despliegue desde CitrixStartCommandWrapper.java. Reproduce el despliegue de la plantilla CentOS predeterminada en XenServer 8.4 e inspecciona cómo se seleccionan el sistema operativo invitado y la plantilla. Se considera terminado cuando la plantilla CentOS compatible se despliega correctamente sin que se produzca el error "Cannot find Template CentOS 7".

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
