Description of problem:

While importing a VM I get this popup error:

win2008_32bit:

    Cannot import VM. VM's Image does not exist.

Jiri, 

I suspect something is wrong with the export path, can you please execute the following commands on the hypervisor:

tree /rhev/data-center/ffec9aa4-692c-11e2-9e91-001a4a013f3a

ls -l /rhev/data-center/ffec9aa4-692c-11e2-9e91-001a4a013f3a/131d564c-52d1-4bba-8d60-39e889a8bc08/images/62787b06-d836-4e14-afc7-023e08aeee96

vdsClient -s 0 getStorageDomainInfo 131d564c-52d1-4bba-8d60-39e889a8bc08
