   @GabrielBrascher need your advice since you guys worked on the local migration with KVM.
   
   I saw a case (didn't reproduce it myself, but while working with the customer, on **4.13**) that when KVM is using local storage, and you try to put a host into maintenance, the following seems to happen:
   - User VMs - not sure if they are migrated away - can't say for sure - but I assume they are.
   - CPVM and SSVM are NOT live migrated (with storage), fails as before
   - VRs are live migrated with their storage/volume to a new host - BUT the volume format in DB seems to be set to RAW (again, this is based other-users data, not my own testing - from the cloud.volumes table)
   
   My question is - what is expected to be happening and what is not, and why is the VR's volume in RAW, vs QCOW2 format? Can you lay down the expected behaviour based on the code you've done so far (in 4.13)
   
   Thanks
