[Libguestfs] Unable to convert vm

[Georg Troxler]

I am unable to convert a vm using virt-v2v. From the trace and debug 
logs I am unable to understand  the cause of the problem. I assume it is 
a permission or configuration issue but I don't know where to start looking.

The following command was issued:

LIBGUESTFS_TRACE=1 LIBGUESTFS_DEBUG=1 virt-v2v -ic 
qemu+ssh://xxx@192.168.xxx.xxx/system -o rhev -os 
192.168.xxx.xxx:/mnt/exports -of qcow2 -oa sparse -n ovirtmgmt testvm

virt-v2v version is 0.9.0.

This is the output produced by the command:
