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 <vm name> 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.

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?

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

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. ;-)

Rich.
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).
