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.

You're using the wrong version of virt-p2v.  You have to use the new
version.

You can build it yourself using the scripts 'virt-p2v-make-disk' or
'virt-p2v-make-kickstart' (read the manual pages first), or try a
recent version that I put here:

Richard,

Thanks for having posted your iso (and the .tar).
I installed the .tar to replace my /tftpboot/p2vboot directory, but when 
booting, I'm hit by the now know bug "Failed to load ldlinux.c32"
(PXELINUX 6.03)

According to what I googled (quite intensively), it may be due to the 
fact that the files contained in /tftpboot/p2vboot are not at the root 
(/tftpboot).

Before going further, I have to say that I still need to succeed in this 
P2V task.
Since long, I'm still very motivated to try and keep progressing.

But today, failures after failures, I must admit I'm getting a little 
tired of all these steps :
- tftpboot install
- pxe setup
- dhcp setup with special options
- p2vboot of the source machine
- failure in the perl script with no explanation
- install of the updated version of virt-p2v.iso, to get debug checkbox
- fsck of the source
- no real help from the debug log (a "cp" command failing, but why?)
- install of a more recent virt-p2v, that can not boot due to 
ldlinux.c32 missing

As the ldlinux.c32 file was missing, I found it somewhere and placed it 
into /tftpboot, then into /tftpboot/p2vboot, but it is not found either 
after gPXE find it ip address.

I tried to use the virt-p2v-make-disk, but it failed to connect to a 
libvirt socket (obviously, there is none running in this VM.)

Well, I take one day off (this issue). I'll go breathe another air, and 
see you tomorrow because I'm getting a point I find it necessary.

Thanks for reading this far. See you tomorow.
