Libguestfs - Nov 2013 - Re: Virtio: 32bit CentOS 6.4 on VirtualBox to oVirt on Fedora 19 64bit via virt-v2v

Hello,
  I've trying to move a 32bit CentOS 6.4 on VirtualBox to oVirt on
Fedora 19 64bit via virt-v2v.  The command I'm currently using is:

virt-v2v -i libvirtxml -of qcow2 -oa sparse -o rhev -osd
xxx.xxx.xxx.xxx:/usr/local/ovirt/exports --network
ovirtmgmt
/usr1/home/williams/Downloads/OpenAthens/VMs/OpenAthensLARuntime2.2.xml

The exciting bit of the XML is:

  <devices>
    <emulator>/usr/bin/qemu-kvm</emulator>
    <disk type='file' device='disk' snapshot='no'>
      <source
file='/usr1/home/williams/Downloads/OpenAthens/VMs/OpenAthens_LA_Runtime_2.2.img'/>
      <target dev='vda' bus='virtio'/>
      <alias name='virtio-disk0'/>
    </disk>
  </devices>

The image is a RAW (taken from the working VirtualBox install) but I
have tried the original image with the same result:

virtio configured, but no virtio kernel found
at /usr/share/perl5/vendor_perl/Sys/VirtConvert/Converter/RedHat.pm

I have looked at the code:

/usr/share/perl5/vendor_perl/Sys/VirtConvert/Converter/RedHat.pm:~490

creating this and dumped the contents of the grub look up:

Sys::VirtConvert::GuestfsHandle=HASH(0x433da98)<
>/dev/VolGroup/lv_root<
$VAR1 = bless( {
                 'onclose' => [
                                sub { "DUMMY" }
                              ],
                 'g' => bless( {
                                 '_g' => 70645888,
                                 '_flags' => 0
                               }, 'Sys::Guestfs' )
               }, 'Sys::VirtConvert::GuestfsHandle' );

If I tell the code to skip the section that calls 'die' the result
becomes:

virt-v2v: Failed to find a kernel_pkg.i686 package to install

Any ideas on how to solve this or what the solution might, please?

Best regards,

Owen.

Hi, Owen,

Could you please pastebin the output of the conversion run with the
environment variable LIBGUESTFS_TRACE=1.

Thanks,

Matt

Done but with LIBGUESTFS_DEBUG=1 (I already had it) :

http://pastebin.com/ZUQ9BMzP

Anyway, I have a working VM now.  I added:

  <capability os='linux' name='kernel'
distro='centos' major='6'
minor='4' arch='i686'>
    <dep name='kernel' minversion='2.6.18-128.el5'/>
    <dep name='lvm2' minversion='2.02.40-6.el5'/>
    <dep name='selinux-policy-targeted'
minversion='2.4.6-203.el5'
         ifinstalled='yes'/>
  </capability>

to /var/lib/virt-v2v/virt-v2v.db

I hope this is useful.

Best regards,

Owen.
