Re: [Libguestfs] p2v with cciss failure

I have continued on with my attempts to get p2v working will little

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.

The file /var/log/virt-p2v-server.1330551856.log contains

I don't think this error has anything to do with the cciss controller, as I've had it from a number of sources now. 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.

Apologies, but some how I managed to miss your original reply.

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
