t depends.  When is 7.3 due?  If the answer is "next week", then yes, I
can wait.  If the answer is "in a month or four" then no.  ;-)

Thanks, Rich.  I'm honestly not sure what the full log told you that my
snippets didn't, but upgrading to your EL7.3 pre-release packages solved
my problem.

Thanks,

Now back to continuing my setup and testing (and backups).

Yes you're right. That change was not back-ported to the version of
virt-v2v on CentOS 7.2. But if I understand things correctly it should
appear in CentOS 7.3. Is waiting for Centos 7.3 an option for you?

You can't just patch the code localy (it's not Python). You'd need to
recompile the virt-v2v binary.

Re: [ovirt-users] Import of OVA fails in 4.0.4

[Derek Atkins]

Hi again,

After a bit more research I found this message in libguestfs[0] that seems
to imply the issue is related to Fedora 23 in that dracut was moved from
/sbin to /usr/bin.  Apparently this was fixed in libguestfs on January 28,
2016 by a change to convert_linux.ml [1].  But apparently this change
isn't in the centos-7.2/ovirt-4.0.4 packages?

I just looked through my ovirt host and canot find "convert_linux.ml"
anywhere, so I have no idea how to actually apply this patch locally.

Short term I suppose I can fix this by adding a symlink in the VM and
repackage the OVA, but it would be nice to actually get this bugfix
propagated; it's been almost a year?

Thanks,

-derek

[ovirt-users] Import of OVA fails in 4.0.4

[Derek Atkins]

Hi,
I just tried using the OVA import feature in 4.0.4 to import an OVA file
created from VMware-Workstation-12.  I packaged the OVA, got it onto my
ovirt host, and then go the Admin GUI and under the Virtual Machines tab
clicked on Import.  From there I chose Source:  VMware Virtual Appliance
(OVA), and selected the (local-to-the-host) path where I put the OVA
file.  After clicking Load it displayed the vm name in the window.  I
click on that and click the right arrow to and then Next.  Then I select
my storage domain to use and continue.  It loads the VM and starts to
process it internally with virt-v2v, but then it inexplicably fails.
The only message in the GUI is: 
   Failed to import Vm  to Data Center Default, Cluster Default

I tried to look into /var/log/vdsm/vdsm.log looking for any errors.  I
found this:

Thread-88166::ERROR::2016-11-05 16:36:09,219::v2v::674::root::(_run) Job u'cdb1e
eb7-63f3-46e8-abd5-5292dcc8809a' failed
Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/vdsm/v2v.py", line 669, in _run
self._import()
  File "/usr/lib/python2.7/site-packages/vdsm/v2v.py", line 696, in _import
self._proc.stderr.read(1024)))
V2VProcessError: Job u'cdb1eeb7-63f3-46e8-abd5-5292dcc8809a' process failed exit
-code: 1, stderr: virt-v2v: error: unable to rebuild initrd 
(/boot/initramfs-4.2.6-301.fc23.x86_64.img) because mkinitrd or dracut was 
not found in the guest

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

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

I don't understand this error because /usr/bin/dracut certainly exists
in the VM.

Anyone have any suggestions on how to get around this?

Thanks,

-derek
