Description of problem: Currently it is possible to perform a p2v/v2v operation at a regular data domain. After doing this, the guest "disappears". We should avoid this user error by checking that the type of the domain is an export storage domain (apparently CLASS=Backup in the domain metadata according to AiC)
The way to do this is to look for the <UUID>/dom_md/metadata file and look for the CLASS= field. It is CLASS=Backup for export storage domains and CLASS=Data for data domains: $ find v2v-rhevm-export v2v-rhevm-data -name metadata | xargs grep CLASS v2v-rhevm-export/39b6af0e-1d64-40c2-97e4-4f094f1919c7/dom_md/metadata:CLASS=Backup v2v-rhevm-data/b592eac5-7c12-4843-ae51-7b0f90a9dfb4/dom_md/metadata:CLASS=Data However if we are going to support exporting directly to data domains then we may in fact *not* want to do this check.
