[Users] VM wont restart after some NFS snapshot restore.

[Federico Simoncelli]

Hi Usman,
 can you paste somewhere the content of the meta files?

 $ cat 039a8482-c267-4051-b1e6-1c1dee49b3d7.meta 8d48505d-846d-49a7-8b50-d972ee051145.meta

could you also provide the absolute path to those files? (in the vdsm host)

Thanks,
-- 
Federico
