Comment 4 Ilanit Stein 2019-06-26 10:45:41 UTC
Verified on CFME-

Checked with 2 cases:
VMware->RHV migration, VDDK, of 20 VMs/100GB disk, and Provider max concurrent VM migrations: 20, and Max concurrent VM migrations, 2 conversion hosts, per conversion host: 10.
Storage type: VMware- ISCSI, RHV- FC.

VMs were distributed evenly, between the 2 conversion hosts, 10:10.

Same env, but with 2 conversion hosts, per conversion host: 5.
On first round, the VMs were distributed evenly, 5:5.
then 1 vM failed on Bug 1719689 - [v2v][RHV][vddk] 1 out of 10 VMs failed migration, on CFME failed to read the state file. 
As a result 1 additional VM started to be migrated to the conversion host, on which the first VM failed migration.
So the distribution became 5:5, again.
After the first round ended, the second round distribution was 4:5
This is even distribution, since only 9 VMs were left to migrate.
the second round ended with a second VM migration failure, on Bug 1724040 - [v2v][Scale][RHV] VM migration fail on "start is not permitted at state running"
