Looking a bit more closely, virt-v2v seems to have trouble seeing
anything at all on the source disk.  So something may have gone badly
wrong.  Tell me about what OS you expect the source (physical) machine
to have, and also something about what hardware it is using for its
disks (SCSI? RAID? etc).

Hi Richard,

Thanks for your replay,

We are using Fedora 21 with SAS drive and RAID 0 config on both Physical
and conversion server.


Thanks,
Tejas

Greetings Richard,

To add to the above information, we are following the understated steps:

   1. We have 2 BL460c (Gen8) with Fedora 21 installed. Both the
   machines(BL1 & BL2) have been updated with virt-v2v packages
   2. On BL1, we execute the following commands:
   1. virt-p2v-make-kickstart fedora
      2. livecd-creator p2v.ks
   3. After creating the "livecd-p2v-2xxxxxx.iso" file, we launch the
   'virt-manager', from BL1
   4. Create a new virtual machine using the 'File' option
   5. Click on 'Begin Installation' after step 4
   6. User is shown the 'Conversion Server' GUI login screen
   7. Enter the credentials & click on 'Test Connection with Conversion
   Server'
   8. 'Next' button is enabled
   9. Click on 'Create p2v' and after sometime, the process is exited
with
   status "-1"
   10. The earlier attached log file is generated in BL2 (conversion
   server) under /tmp/virt-XXXX directory

Hope it helps to solve the issue.


Regards,

Ravi Chaudhary

We're going to need a bit more information about the hardware
in the physical server, like what 'RAID 0' means - hardware RAID?
What precise RAID controller hardware?

My other advice would be to log in to the virt-p2v shell (it's
on one of the other consoles, like Alt+Ctrl+F2) and run 'dmesg'
to see what hardware the virt-p2v kernel is seeing.  If possible,
copy 'dmesg' off and post that.

Note I don't care about the conversion server - it is unlikely
to be the problem.

Rich.
