I was hoping that it works, but the conversion hanged at the 7th /9 disk 57,03% since 1.30 AM...
[19351,0] Copying disk 7/9 to /tmp/v2v.UgUPSx/0a6404e0-2857-45e4-9322-c1ada5ae13fb/images/0123ddcd-f88d-43d0-b836-2cabe57beac3/d0fe6d79-b846-41ca-ac94-835b97488685 (raw)

The qemu-img idles :
23338 root 20 0 227300 7332 3868 S 0,0 0,1 0:48.29 qemu-img
I have no errors in dmesg, but NFSD state is D :
11263 root 20 0 0 0 0 S 0,0 0,0 0:00.00 lockd
11266 root 20 0 0 0 0 D 0,0 0,0 1:52.51 nfsd

11273 root 20 0 0 0 0 D 0,0 0,0 1:53.72 nfsd
I think the problem is there, I have to say you that my NFS EXPORT_DOMAIN for Ovirt is on the same machine (because of need of large volume space "4Tb" to convert big vmdk images) so the NFS volume /data/big_import/IMPORT is used to convert images and to send (in fact on the same HD via NFS) it to oVirt Manager.
I've tried before to convert locally images but they didn't appeared in "Import VM" on the oVirt Manager.
Maybe it was a bug from older version of libguestfs and works today ?
If you have a better proposition to make this conversion not using the -o rhev -os "nfs share", I'll friendly accept !!!!

I run again a conversion to try to catch a core dump...

That's qemu, not qemu-img.

These are a problem, if they are coincident with qemu-img hanging.
Use 'dmesg -w' to check.

You can ignore this warning. It is meaningless for the end user and doesn't matter.
