Description of problem:
Trying to import a specific VM using VMware fails, though in the log I can only seem to find the following error (see [1])
The question is how can I use virt-v2v with debugging enabled through oVirt, and is there a way for oVirt to reflect the message got from virt-v2v

  virt-v2v -v -x [...]

(In reply to Maor from comment #0)
There is no need to enable debugging in virt-v2v for that, we get errors that happen in the middle of the conversion without debugging mode.

Note that we parse the output of virt-v2v. So we get the description of errors from virt-v2v as text, therefore we decide not to show it in the audit log. So  audit log only shows that the conversion failed and to see why you should look for it in the engine/vdsm log.

I believe that if we ever change the API with virt-v2v to be based on codes for errors instead of getting it as text, then we will be able to map codes to presentable messages in audit logs.

According to c#2 there seems to be a reasonable way for getting these errors.
