Issue is similar to 'https://bugs.launchpad.net/cinder/+bug/1301943' .

 '1301943' - is related to 'vmware_disktype=sparse' image type but this bug is related to 'vmware_disktype=preallocated'

However as per comment 2 of respective bug : for all Non-StreamOptimized images cinder driver logic should not select destination as vsan datastore. once bug 1301943 get fixed we should not see this issue.
