Bug 1280501

Suggest going to:

https://vCenterServer/folder/

and comparing the URLs against the ones that virt-v2v is
trying to download from.  As the error message suggests,
the --dcpath parameter may be useful.

Actually I think it's *without* the slash, so:

https://vCenterServer/folder

I did try that but I am honestly not sure with folder what you mean. The URL I have on the VMware Web UI is not even close to looking like the one virt-v2v is
trying to download from.

This is the URL if I navigate to the datastore folder containing the VM:
https://vCenterServerName:9443/vsphere-client/#extensionId=vsphere.core.datastore.manage.filesView;context=com.vmware.core.model%3A%3AServerObjectRef~21F3B6D6-26FB-430E-BA4A-BAF302EBA2F8%3ADatastore%3Adatastore-23633~core.

Plus, as I mentioned before. The exact same command on the exact same VM works with the older version of Virt-v2v.

Should I upgrade my Libvirt version maybe?

If I run a yum update though I do not get anything higher than libvirt-client-1.2.17-1.el7.x86_64.

Do I need a specific repo?

Put https:// + the name of your vCenter server + /folder into the
URL field of your web browser.  It will show a list of data stores.
Navigate through these to your VM.  Find the final URL of the VM's
disk image, and add that as a comment to this bug.

https://vCenterServerName/folder/conversion-test-vm%20%2843f00f9c-276b-4bc7-9c2f-66c41824960e%29?dcPath=Eagan%2520Developer%2520Cloud&dsName=virtual%255fpcf0221%255fsnap07

There there is the list of files, VMDK-flat included.

That's a VM called "conversion-test-vm (....)" whereas the one
you selected in the original description was called
"conversion-test-vm2 (...)".

Assuming that was not a mistake, you might want to try adding
one of the following parameters:

  --dcpath 'Eagan Developer Cloud'
  --dcpath 'Eagan%20Developer%20Cloud'
  --dcpath 'Eagan%2520Developer%2520Cloud'

(Or just rename all your VMs and stuff so you don't have spaces
and other non-alphanumeric characters in them, which could be
the path of least resistance).

https://vCenterServername/folder/conversion-test-vm2%20%28f97c63bc-e711-4281-bb57-627c86e06b18%29?dcPath=Data%2520Center%2520Name&dsName=virtual%255fccf0444%255ft1%255fsnap07%255f01

The above is the path to the vm2.

What I still do not understand is why all these vms can be converted fine by the older version of virt-v2v and not from the latest.

Try --dcpath 'Data%2520Center%2520Name'

This may actually be a quoting bug, but it's hard to tell because there
are so many layers of quoting going on here.

By "older version" what *precise* version worked before and what
precise version doesn't work now?

I have specified the older version in the first comment:

Additional info:
The same command works using the following tools versions:
Libvirt version:
libvirt-client-1.2.17-1.el7.x86_64

Virt-v2v version:
virt-v2v-1.28.1-1.48.el7.x86_64

However, I tried --dcpath 'Data%2520Center%2520Name' and doesn't work:

virt-v2v: error: vcenter: URL not found: 
https://c111aqz.mgmt.tlrg.com/folder/conversion-test-vm2%20%28f97c63bc-e711-4281-bb57-627c86e06b18%29/conversion-test-vm2%20%28f97c63bc-e711-4281-bb57-627c86e06b18%29-flat.vmdk?dcPath=Eagan%252520Developer%252520Cloud&dsName=virtual%5fccf0444%5ft1%5fsnap07%5f01

The '--dcpath' parameter may be useful.  See the explanation in the 
virt-v2v(1) man page OPTIONS section.

If reporting bugs, run virt-v2v with debugging enabled and include the 
complete output:

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


Tried this instead, --dcpath 'Data%20Center%20Name' and it fixed the issue, now the tool connects fine and can start the conversion:

[   0.0] Opening the source -i libvirt -ic vpx://TLR%5cm0035016.tlrg.com/Eagan%20Developer%20Cloud/F%20Module/C915PYA/c475zfc.int.thomsonreuters.com/?no_verify=1 conversion-test-vm2 (f97c63bc-e711-4281-bb57-627c86e06b18)
[   2.6] Creating an overlay to protect the source from being modified
[   8.2] Opening the overlay
ecc..

I still would like to understand if I can upgrade Libvirt to another more recent version to avoid adding this parameter.

Regards

It's almost certainly more fallout from the fix for bug 1256823.

There's no good solution here, but the possible solutions are:

 - Try different --dcpath parameters until something works.  I
   suggest removing layers of quoting, so:

      --dcpath 'Data%20Center%20Name'
      --dcpath 'Data Center Name'

 - Rename your data center so it doesn't contain spaces or other
   special characters.

 - Upgrade to the libvirt version which supports <vmware:datacenterpath>
   https://www.redhat.com/archives/libvir-list/2015-September/thread.html#00201
   However you'll also have to switch to upstream virt-v2v since
   the one in RHEL 7 doesn't have the commits to read this info
   from libvirt.

*** This bug has been marked as a duplicate of bug 1256823 ***

Richard,
What do you mean with switch to the virt-v2v upstream? I do not really have the steps clear to do so.
 
Thanks

My suggestion is that you use Fedora 23 as your virt-v2v conversion
server (instead of whatever you are using now - RHEL 7.1 I think).

This version of Fedora includes a version of libvirt (>= 1.2.20) which
has the <vmware:datacenterpath> feature.

You will still need to use libguestfs >= 1.31.16.  That is not
available in Fedora 23, but there are two options for that:

 - (Easier) Add the Rawhide repo to your Fedora 23 guest and
   install the version of virt-v2v from Rawhide.  The following
   commands should be sufficient:

   # dnf upgrade dnf
   # dnf install dnf-plugins-core fedora-repos-rawhide
   # dnf --enablerepo=rawhide install --best virt-v2v

 - (Harder) Compile libguestfs from source and use virt-v2v like this:

   ./run virt-v2v [...]

   If compiling libguestfs from source, read the README file carefully
   before starting.

Thank you Richard,
so if I understand well my only option is to rebuild my environment on a Fedora23 OS instead of using CentOS or keep using the current one with the --dcpath option. Correct?

My last question is, will I be able to run the last version of virt-v2v that will support windows 2012 on my CentOS once it will be released?
If I can, I'd prefer not to rebuild everything from scratch unless I must use libvirt 1.20 for the last virt-v2v release.

Thanks for you help as always!
