There's got to be some difference between your staging

your production environment, and I'm pretty sure it has nothing to do
with the version of oVirt.
Are you running virt-v2v inside a virtual machine, and previously you
ran it on bare-metal? Or did you disable nested KVM? That seems like
the most likely explanation for the difference (although I'm surprised
that the difference is so large).

Hello Rich,
i'm running virt-v2v throught the import option of oVirt.
[root@kvm01 ~]# rpm -qa virt-v2v
virt-v2v-1.36.3-6.el7_4.3.x86_64
[root@kvm01 ~]# rpm -qa libguestfs
libguestfs-1.36.3-6.el7_4.3.x86_64
[root@kvm01 ~]# rpm -qa "redhat-virtualization-host-image-update*"
redhat-virtualization-host-image-update-placeholder-4.1-8.1.el7.noarch
redhat-virtualization-host-image-update-4.1-20171207.0.el7_4.noarch
(yes, i'm running RHV, but i think this shouldn't change the behaviour)
I don't set anything in the commandline or whatever, i set only the
source and destination throught the API. So virt-v2v is coordinated
via vdsm and runs on the bare-metal host.
The network distance is "0", because vcenter, source vmware hosts, kvm
hosts and ovirt hosts lies in the same network. The only annotation is
that also vCenter is a VM, running on esx environment.
Network interfaces both on source and destination are 10Gbit, but
there may be a little slowdown on vcenter side because has to get the
data from esx's datastore and forward to the ovirt host.
Just for reference this is the virt-v2v i found with ps on an host
when converting (this may be not the one that generated the output i
reported before, but all are the same):
/usr/bin/virt-v2v -v -x -ic
vpx://vmwareuser%40domain@vcenter/DC/Cluster/Host?no_verify=1 -o vdsm
