[ eploy a qcow2 image within the proxmox VM ]
To deploy an existing qcow2 image , create a blank VM.
click “create VM”
on the “CD/DVD” tab , choose “do not use any media “

Where is the path to vm-100-disk-1.raw ?
check the local storage path.
Folder View -> DataCenter -> Storage.
The path to the local storage seems to be /var/lib/vz.
