Bug 1828289

As mentioned in the other bug, please provide all the details about the conversion:
- the version of virt-v2v
- the version of virt-p2v
- the hardware of the machine being converted
- the OS on the machine being converted
- the complete logs of the conversion

You can find more details in the documentation of virt-p2v:
http://libguestfs.org/virt-p2v.1.html
see the "HOW VIRT-P2V WORKS" section about which files to fetch from the conversion server after a failed conversion.

I have shared it on mail as I couldn't attach all the details here.

I don't think I received the email; however if you cannot attach it,
then you can send (not huge) messages to libguestfs, referencing
this bug so we know what it refers to.  Note this is a public mailing list
and anything you send there will be seen by the whole world.

I forward it to libguestfs with the bug id mentioned.

This is only the virt-v2v conversion logs, and it shows:

+ lvm pvscan --cache --activate ay
  Couldn't find device with uuid qYh5Q0-zM9p-LLqV-tfqL-YN5a-z7Nt-BLzI7a.

Which explains why later the mount fails:

libguestfs: trace: v2v: mountpoints
guestfsd: <= mountpoints (0x93) request length 40 bytes
command: lvm 'lvs' '-o' 'vg_name,lv_name' '-S' 'lv_role=public && lv_skip_activation!=yes' '--noheadings' '--separator' '/'

guestfsd: error: stat: /dev/centos/home: No such file or directory

A possible explanation is that not all the disks are passed to virt-v2v. Sadly, we need the complete set of virt-p2v logs.
Please check http://libguestfs.org/virt-p2v.1.html#how-virt-p2v-works out and create a tarball with *all* the files in the directory on the conversion host after a failed migration.

Created attachment 1687148 [details]
attached the zip files of all the logs.

attached the zip files of all the logs.

OK, the additional data give more details now, although I still cannot figure out why one of the PV devices is not found.

Can you please boot the OS that you are try to convert, and paste the result of the following commands as root:
- vgs -v
- pvs -v
- lvs -v
- mdadm --examine
- ls -lh /dev
- ls -lh /dev/centos

Also, did you create the virt-p2v disk image on your own? It looks like you installed virt-p2v-maker on CentOS, then ran virt-p2v-make-disk -- is it correct?

Thanks again for the additional information.

Pino, 

I just sent it in a mail, Let me know if not received.
