unfortunately upgrading virt-v2v is not an option. Would be nice, but
integration with vdsm is not yet ready for that options.

I'm not migrating the same guests, i'm migrating different guest, but
most of them share the same os baseline.
Most of these vms are from the same RHEL 7 template and have little
data difference (few gigs).
Do you know which is the performance impact on vcenter? I'd like to
tune as best as possible the vcenter to improve the migration time.
We have to migrate ~300 guests, and our maintenance window is very
short. We don't want continue the migration for months.
