I am trying to create external snapshots of a kvm guest machine and have not been able to
do so. 

In accordance with :

I have used the command line :

snapshot-create-as --diskspec vda,snapshot=external,file=/u4/guest/MaBa-
clone/test.snap.img--domain MaBa-clone --name MaBa-clone_snap --description "Snap
before  9Aug2020"

This command line gives me the error :
error: unsupported configuration: disk 'vda' must use snapshot mode 'internal'

Is it possible to perform an external snapshot of a kvm guest?
