I have continued on with my attempts to get p2v working will little success.
I have changed my server to Fedora 16 and finally got an XP with a
single SATA disk (sda) to work. I think that this means that the
current virt-p2v.iso just doesn't work with the packages that are
available on Centos 6 at the moment.
However, the machines that I currently need to actually migrate all
have cciss controllers of some sort in them. For testing I have two
very different servers with different controllers in them that both
use the cciss driver that fail to complete the transfer of the image.
Debug output is listed below, but doesn't give me any clues as to what
to look at next.

Mar 1 11:33:14 c2cl00 virt-v2v[6721]: Automatically cleaning up
volume win2008-cciss_c0d0 from pool {pool}.
The file /var/log/virt-p2v-server.1330551856.log contains
-----Start
virt-v2v: Error receiving data:
-----End
This failure is repeatable for each server in that each will fail at
the same point if I try the transfer again. The amount of data
transferred before failure for each server is different.
I have tried different array configurations and the transfer fails
with differing, but repeatable for that particular configuration,
amounts of data transferred.
The destination storage pool is an LVM volume group and the volume is
not "Automatically cleaning up" as the log says and is not called
"pool" as I think that the log is indicating.
The virt-p2v.iso being used was created on a Fedora 16 32 bit machine
and has virt-v2v 0.8.5 installed, as does the server that I am now
using.
At this point I am leaning towards there being an issue with the cciss
drivers on the virt-p2v.iso, but am not sure what to try next.
Any help would be appreciated.
Thanks
Mike

There appears to be some kind of race in the code which sends disk data. I'm currently working on trying to track it down.

Let me now if there is something I can do to help with tracking this down. I have a couple of machines here that reliably fail that I can test on. Thanks Mike
