Hi Tata,

Basically you can workaround in vm_tempalte table for existing template or 
user_vm_details for provisioned VM. My PR just fix non-“osdefault” 
rootdiskcontroller with Sharedfs, if you want to do so, you can update the 
cloudstack jar file. Eg "jar uf cloudstack-4.20.1.0.jar conf/fsvm-init.yml"


Regards,
Levin
