We have many issues migration with 1G and 18-25 vms.
Is slow, stuck, failed. Switched to 10G and set migration limit to
5000Mbps (actually this is don't work, but if don't set this field,
limit is 1000Mbps!) - 25vms migrate ~ 30seconds in total.

What is your Migration Network?

VDSM has the following config option:

Hello.
What is your Migration Network?
We have some hosts that have 60 vms. So this will create a 60 vms migrating
simultaneously.
Some vms are under so much heavy loads that migration fails often (our guess is that
massive simultaneous migrations does not help migration convergence) - even
