Description of problem: virt-v2v fails to convert an Oracle 5.8 VMware vm Version-Release number of selected component (if applicable): libguestfs-1.28.1-1.17.el7.x86_64 virt-v2v-1.28.1-1.17.el7.x86_64 The following error is thrown: [ 257.0] Converting Oracle Linux Server release 5.8 to run on KVM virt-v2v: error: virt-v2v is unable to convert this guest type (linux/oraclelinux) Isn't Oracle Linux supported by the new virt-v2v?
Created attachment 969059 [details] 0001-v2v-Treat-oraclelinux-as-if-it-was-plain-RHEL-RHBZ-1.patch The attached patch is only compile-tested. It should make the error message go away, and depending on how close OEL is to RHEL, it may even make the conversion work.
How can I integrate that in my CentOS 7 machine where virt-v2v is installed?
Download the libguestfs source RPM from the repo, and rebuild it with the patch. There are various online tutorials for this. These ones seem fairly sensible: http://bradthemad.org/tech/notes/patching_rpms.php http://www.owlriver.com/tips/patching_srpms/ As an extra tip, to save a lot of time by avoiding running the test suite when rebuilding the package, put this into your ~/.rpmmacros file: %libguestfs_runtests 0
The conversion using the patch works and the VM is copied in the oVirt Export Domain. However during the conversion I got the following warning: it-sybmon-01 (6083acd1-78b7-49be-97e5-288bc885a0b3) virt-v2v: warning: cannot write files to the NFS server as 36:36, even though we appear to be running as root. This probably means the NFS client or idmapd is not configured properly. You will have to chown the files that virt-v2v creates after the run, otherwise RHEV-M will not be able to import the VM. I did a chown vdsm.kvm on the export domain recursively but when I tried to import the VM on a data domain it failed. When I tried again I got the following error: cannot import vm. the storage domain already contains the target disk(s).
(In reply to Sokratis from comment #4) > cannot import vm. the storage domain already contains the target disk(s). oVirt errors are often unhelpful. http://libguestfs.org/virt-v2v.1.html#debugging-rhev-m-import-failures Anyway you need to take this issue up with the oVirt folk. Thanks for testing the patch, it is now included upstream (in libguestfs >= 1.29.19), and so I am closing this bug.
Hi, As I'm facing this issue when trying to P2V some OracleLinux servers, and as I'm using the livecd-p2v-201412160442.iso liveCD, I have no obvious way to rebuild the RPM. This liveCD is shipped with libguestfs 1.28.1 and does not contain this patch. Is it planned to release a newer version of the liveCD shipped with a recent version of libguestfs? Regards.
I'd recommend a newer version of the p2v ISO, eg: http://oirase.annexia.org/virt-p2v/RHEL-7.2-preview/ The patch is for virt-v2v (not p2v) and there are no plans to include it in RHEL since it would require us to test conversions of OEL too, which would be a very big task. However feel free to apply it to your virt-v2v sources and see if it works.
Richard, Not being sure of having understood your answer, I just downloaded and tried with the iso you just mentionned and the same error message is appearing (virt-v2v: error: virt-v2v is unable to convert this guest type (linux/oraclelinux)). This iso is still shipped with libguestfs 1.28.1 About your patch, is it to be applied on the conversion server, or on the liveCD? If it is on the conversion server, it seems more easy to try to apply it.

This iso is still shipped with libguestfs 1.28.1 The new ISO is nothing to do with this bug. I just thought you'd like to use an ISO which is more up to date and where we have fixed many other bugs. > About your patch, is it to be applied on the conversion server, or on the > liveCD? > > If it is on the conversion server, it seems more easy to try to apply it. The patch should be applied to virt-v2v, ie. the conversion server. See comment 3.
