[Users] virt-v2v fail - GuestfsHandle.pm error + Redhat.pm error
Hi, After having successfully migrated Debian, XP, 2003, 2008 VMs, I'm stuck with a migration I was expecting to be easy : RHAS3. Here is the error log I get :

I don't mind the warnings and I also had such errors I was able to correct manually. But here, the last two lines are lethal. It seems oVirt tries to guess which OS is imported, and tries to do specific actions, and do them bad. Either there's a way o prevent oVirt from guessing, either there's a way to correct the actions oVirt is failing to do... Googling was not that helpful about this issue. Regards. -- Nicolas Ecarnot

I think you had better to tell which version of virt-v2v and on which platform. eg: virt-v2v-0.8.7-7.el6_3.x86_64 on CentOS 6.3 otherwise the lines referred could not be the same as yours... Gianluca

Hi Gianluca, Thank you for your answer. You are right, I have to precise the versions implied. - Fedora 17 64 bits - virt-v2v.x86_64 version 0.8.8-1.fc17 - every ovirt component is of the family 3.1.0-4.fc17 I installed nothing exotic nor special. Just following the oVirt website doc. Do I have to debug the perl script, or is there an option I can tweak in the virt-v2v command? -- Nicolas Ecarnot

I'm not totally clear what "RHAS 3" is, but you're correct that virt-v2v has to detect[1] the type of operating system in the guest in order to determine what operations it has to perform on that guest. It uses the configuration file /etc/virt-v2v.conf to map the guest type into drivers that have to be installed, but some of this is also hard-coded inside the program. Matt (CC'd) might have some more suggestions. Rich.

RHAS stands for redhat advanced server. In our case, this is just an old "Red Hat Enterprise Linux AS release 3 (Taroon)".
It uses the configuration file /etc/virt-v2v.conf to map the guest type into drivers that have to be installed, but some of this is also hard-coded inside the program.

I'll be glad to hear from him.

I had to install libguestfs-tools.x86_64 to get virt-inspector, and it correctly find it is a RH 3. Am I missing some more packages for the perl scripts to work correctly? -- Nicolas Ecarnot

virt-v2v should depend on everything it needs, and there was no error message indicating that anything was missing. AFAIK RHEL 3 should work (for v2v), but we'll see what Matt says.

I forgot to write that after the installation of the package mentionned above, I still have the exact same perl error messages. -- Nicolas Ecarnot

I'm so sorry to debug that issue in a so crappy manner, but I have to keep going. I just commented out "_configure_boot($kernel, $virtio, $g, $root, $desc);" in Redhat.pm and it ran with no error. I'd be very glad to hear from Matt... -- Nicolas Ecarnot

I'd need to know exactly which version of virt-v2v you're running in order to diagnose the above. I think the unknown fd0 was fixed a while back, though. Are you running the latest available version? Matt

FWIW, I've wasted hours on this one too, and just commented out the line above. I'm running a completely clean install on a Fedora 19 server, and the client is running Fedora 20 that I'm trying to v2v from KVM to oVirt. As a side note, It'd be nice, especially in the case that there might be some ignored, and other fatal errors, that errors that live on a "die" line also state "DIE" or "FATAL ERROR" in the output they give to the console.
