Litton Peng commented on CLOUDSTACK-5070:
-----------------------------------------
I investigated the source code and found this cause by when the agent process
the GetVmDiskStatsCommand, doesn't consider the case whether the VM attache an
iso file. if it's a iso disk, the path cann't be queried in volumes table.
> The disk statistics cann't be updated during the migration if VM attach an
> iso file.
