Richard, Matthew et al,

I'm extremely glad to announce that last night, _we_ (you and I) were 
finally able to complete a conversion of this tricky windows 2003 server.

When completed, the import into oVirt went fine, but booting lead to a 
BSOD, which I corrected by merging mergeide.reg into the source machine 
and starting the whole process again. Then I fine tuned it by installing 
the dedicated virt drivers (virtio, net, scsi) and it eventually worked.

I guess the success key was that very last release of the packages 
coming from the libguestfs-RHEL-7.1-preview.repo repo :

[root@serv-p2v-adm1 etc]# tail -8 /var/log/yum.log

For me, it has been more than a month of struggle, doc reading, testing, 
and way too many failures; but thanks to the libguestfs team, I succeeded.
So I'd like to express my sincere thanks to Richard and Matthew for your 
support and professionalism.

As I explained it this long thread, I will have many more machines to 
convert, so they may be parts I may wish to see unsharpened (iptables 
concerns, sshd_config, livecd via pxeboot), but I know now that the code 
is correct and the pieces are fitting.

Once again, thank you gentlemen.

Hang on there ...  Using 'mergeide.reg' should *not* be necessary ...

What was the BSOD?

I tried many reboots, and F8 > choose different debug/recovery options.
They all lead to windows beginning to boot then BSOD 0x0000007B.

If you want the precise sub figures between parenthesis, I must admit I 
haven't them anymore. Sorry.

Google is full of answers leading towards the use of mergeide.reg, and 
my former experience with its use was good, so I did not hesitate and 
was right.

Does your answer above implies that amongst the tons of things 
libguestfs is doing to the FS, it also manipulate the registry in order 
to do the same changes that mergeide.reg does?
