Migrate XenServer to RHEV

Best regards

I want to migrate Virtual Machine with OS guest (RHEL.6_x64) that run on Hypervisor XenServer. I read documentation VIRT-V2V Guide but I don't understand some things. This the scenario

Machine 1

• HOST ---->XenServer Hypervisor IP: 192.168.1.18
• GUEST_A --->"RHEL_x64" Operate System IP:192.168.1.17

Machine 2

• HOST ---> RHEL-H Hypervisor 6.4 IP: 192.168.1.15
• GUEST _B ---> "Centos Minimal" Operate System
• GUEST_C ---> EMPTY -- Here should be GUEST_A From XenServer.

Machine 3

• RHEV-Manager software.

My question is virt-v2v software where should be installed, on RHEL-Manager or RHEL-Hypervisor or Guest OS ???
