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

Inizia da CitrixResourceBase.java:1300 e dal percorso di avviso di Xenserver84Resource, quindi traccia il deployment a partire da CitrixStartCommandWrapper.java. Riproduci il deployment del template CentOS predefinito su XenServer 8.4 e verifica come vengono selezionati il sistema operativo guest e il template. Il lavoro è completato quando il template CentOS supportato viene distribuito correttamente senza l’errore "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
