Well, anyway, on the source, I forced a fsck, then tried again, with no

I am using libguestfs through oVirt 3.4 (RHEV), and whoever knows this 
project knows how intricated the packages are.
As this is a production environment, I can not play with trying to 
change libguestfs on the oVirt manager.
But I would be enthusiastic to install a dedicated P2V server, on RH7, 
with the very last libguestfs, if that helps me to insure our future P2V 
will succeed.
But according to what I understood so far, I'm not sure one can install 
such a P2V server, independent of any oVirt setup.

As a matter of fact, I'll be glad to test the last libguestfs version, 
but I don't know where I could use it?

Just install a RHEL 7.0 VM, and upgrade it with the packages by
following the instructions here:

https://www.redhat.com/archives/libguestfs/2014-May/msg00090.html

The other minimum requirements are covered here:

Richard, Matthew et al,

In a VM, I installed a RHEL 7.0 and tried to install libguestfs-tools 
but I saw there were many errors related to missing repositories and 
other errors.

I wasn't able to cope with these issues.
So I tried to install another VM with CentOS 7.0, and I tried to install 
libguestfs-tools.

Another problem came from the too old version of glusterfs-api, so I 
added the lastest glusterfs repo definition, upgraded, and succeed in 
installing libguestfs-tools and virt-v2v.

Then I PXE-boot my source physical machine (well, at present, at test 
time, another VM but whatever), when getting the graphical prompt to 
connect to the conversion server, I get
"Failed to start virt-v2v-server on remote server".
though I witness the SSH connection is OK on the conversion server.

On this conversion server, I find no trace of any 
/usr/bin/virt-p2v-server binary.

See :

[root@serv-p2v-adm1 log]# rpm -qa virt-v2v
virt-v2v-1.28.1-1.11.el7.x86_64

[root@serv-p2v-adm1 log]# rpm -qa virt-v2v
virt-v2v-1.28.1-1.11.el7.x86_64
[root@serv-p2v-adm1 log]# rpm -ql virt-v2v

/usr/share/virt-p2v/p2v.service
/usr/share/virt-tools
/usr/share/virt-tools/rhev-apt.exe
/usr/share/virt-tools/rhsrvany.exe

Is this virt-p2v-server really missing, or is it done another way now 
we're on 7.x ?
I ask that because when comparing with the same rpm on a 6.6, it 
contains much more things, amongst them the binary server and the 
numerous perl scripts.
