I mean the screen is totally blank after it boots and tries to go to X. You
cannot type or see anything. if you want, I can record a video and show it
to you.
A video is not going to help. Press the key to get to the console
after boot ([Alt]+[Ctrl]+[F2] or something similar) and have a look at
the journalctl output.

In the right bottom side, where you see the nic MAC address and near it by
default you see the word "Default".
I'm not exactly sure, but if it's the "Network interfaces" section of
the second page of the wizard then that is the network that we try to
connect to.

that's the problem. Once I remove the default "/var/tmp" and try to put my
pool name and starts the conversion, it thinks that I'm using the Local
mode (and I selected the libvirt mode) and when it finishes and it fails,
the end of the log shows:
virt-v2v: error: -o libvirt: output pool ‘NAS-10G’ is not a directory
(type='dir'). See virt-v2v-output-local(1)
It could well be a bug, but take a look at the virt-p2v logs which are
saved under /tmp/virt-p2v-* on the conversion server. That will tell
you what exact command line was used.

It could well be a bug, but take a look at the virt-p2v logs which are
saved under /tmp/virt-p2v-* on the conversion server. That will tell
you what exact command line was used.
I did, and I'm enclosing gzipped copy of the file. Line 4197 clearly shows
it got the correct parameter:
Initializing the target -o libvirt -os NAS-10G

Ah I see. This is a limitation:
https://github.com/libguestfs/libguestfs/blob/f79129b8dc92470e3a5597daf53...
Actually not one that I recall from before (the vast majority of
people using virt-p2v are either creating a file or writing to
RHV/OpenStack/etc).
However this should be easy enough to work around: Set the output
(-os) to some directory on the conversion appliance with plenty of
space. Do the conversion, you'll end up with a libvirt XML file and
the disk images as files. Then use normal ‘virsh’ commands to copy
the disk images to the pool you actually want to use, adjust the
libvirt XML to point to the pool, and create the VM also using ‘virsh’
commands. Would suggest reading the libvirt documentation if unsure
about these steps.

Ah I see. This is a limitation:
https://github.com/libguestfs/libguestfs/blob/f79129b8dc92470e3a5597daf53...
I see. This situation is great if someone wants to move 1 VM from Hyper-V
(for example) to a laptop or to a workstation where he/she is using
virt-manager.
Actually not one that I recall from before (the vast majority of
people using virt-p2v are either creating a file or writing to
RHV/OpenStack/etc).
I got 2 more questions:
1. Is it possible to add to the virt-p2v-make-disk program a parameter
to add kernel parameters? (right now I have to create the image and edit
manually the grub.conf file in the image in order to edit them) - this
could help in situations where someone cannot setup PXE.
2. Is there a way to create the image as a bootable ISO? Hyper-V for
example, doesn't like standard "hard disk" images. I see that kiwi has
this
functionality, but it's only for SuSE.
Thanks again

I got 2 more questions:
1. Is it possible to add to the virt-p2v-make-disk program a parameter
to add kernel parameters? (right now I have to create the image and edit
manually the grub.conf file in the image in order to edit them) - this

The real issue here is what file in the image to edit and how.
You could try editing virt-p2v-make-disk (or a local copy of it) and
add something to the long virt-builder command right near the end of
the file. I would suggest adding an --edit option such as:
--edit '/etc/grub/grub.conf: s/linux (.*)/linux $1 your_parameter=foo/' \
2. Is there a way to create the image as a bootable ISO? Hyper-V
for
example, doesn't like standard "hard disk" images. I see that kiwi has

I actually tried at one point to create a bootable ISO from a
virt-builder image, but totally failed to make anything work ...
You could try the kickstart approach (ie. virt-p2v-make-kickstart) but
then you're in a world of other painful tools such as livecd-creator.

the file. I would suggest adding an --edit option such as:
--edit '/etc/grub/grub.conf: s/linux (.*)/linux $1 your_parameter=foo/' \
At the end I simply used guestmount to mount the image, and edited
manually the
/boot/grub2/grub.cfg and added the parameters.
BTW: I couldn't find a way to tell it to map the NIC to a bridge in the
virt-manager, which parameter should it be?

I found a workaround for this - qemu-img convert to VHDX, then - no need
for ISO ;)
Thanks for your help. I hope within the next few hours to record a video
and upload to youtube about using virt-p2v.
