Hyper-V Replica broker between two domains

Hello,

I have two separate domains with Failover Clusters.

One domain: contoso.local

Failover: CLS.contoso.local

Replica broker: Replica.contoso.local

Nodes: node1.contoso.local, node2.contoso.local, node3.contoso.local, node4.contoso.local

Secondary domain: domain.local

Failover: CLSHV.domain.local

Replica broker: ReplicaBroker.domain.local

Nodes: HV1.domain.local, HV2.domain.local

I have established trust between the domains and added DNS Conditional Forwarders on both domains.

I need to migrate VMs between failover clusters and would use Replica Broker to do this.

I have added a computer object (and replica object) to the Administrator group on all nodes.

I'm going to use Kerberos authentication but it's not working.

Firewall rules are enabled but when I tried to enable replica I got error with Kerberos authentication or connecting to the replica broker where port 80 is not enabled (Hyper-V Replica HTTP Listener (TCP-In) is enabled on all of the nodes).

Any ideas on how to replicate VMs between clusters?

    Hi drClays,

    Hope you're doing well.

    1. Ensure that Kerberos authentication is correctly configured on both clusters.
    2. Ensure that the necessary firewall rules are enabled on all nodes. Specifically, verify that port 80 (HTTP) and port 443 (HTTPS) are open for inbound traffic. You mentioned that the Hyper-V Replica HTTP Listener (TCP-In) is enabled, but double-check the following:

    (1) Hyper-V Replica HTTP Listener (TCP-In)

    (2) Hyper-V Replica HTTPS Listener (TCP-In)

    1. Ensure that the Hyper-V Replica Broker is correctly configured on both clusters.
    2. In the "Hyper-V Settings" of each node, configure the replication settings to use Kerberos (HTTP) and specify the correct ports.
    3. Since you have already established trust between the domains and added DNS Conditional Forwarders, ensure that the DNS resolution is working correctly for all nodes and brokers across both domains.
    4. Use tools like 'ping' and 'telnet' to test connectivity between nodes and brokers on the specified ports.

    Best Regards,

    Ian Xue
