Hyper-V Replication Fails Between Standalone Windows Server 2022 Hosts

Question

I am trying to set up Hyper-V replication between two standalone Windows Server 2022 hosts (not part of an Active Directory domain). Despite following the required steps, I am encountering an error when enabling replication.

The error states:

Enabling replication failed.
Hyper-V failed to enable replication.

Hyper-V was unable to establish a connection with the replica server.

Hyper-V failed to enable replication for virtual machine 'Debian 12': %%12030 (0x00002EFE). (Virtual machine ID E1E8D0E6-A683-4968-8E98-419E2258CDE1)

Hyper-V could not establish a connection to replica server 'WIN-17VPVFVOKGO.local' on port '80'. Error: %%12030 (0x00002EFE).

Note: Enabled the firewall rule: Hyper-V Replica HTTP Listener (TCP-In) on both servers.

Setup Details:

1. Primary Server: Server02
2. Replica Server: Server09
3. Virtual Machine: Debian12
4. Authentication: Kerberos (HTTP) on port 80
5. Environment:
   • Both servers are physically co-located and standalone (not AD members).
     • Firewalls on both servers have the rule "Hyper-V Replica HTTP Listener (TCP-In)" enabled for port 80.
       • Replication is configured to allow connections from any authenticated server.

Steps Followed:

1. Installed the Hyper-V role on both servers.
2. Enabled "Allow this computer to act as a Replica Server" in Hyper-V settings on both host
3. Primary Server: Serve1
4. Replica Server: Server02
5. Selected Use Kerberos (HTTP) and set the port to 80 under the authentication and port settings.
6. Enabled the firewall rule: Hyper-V Replica HTTP Listener (TCP-In) on both servers.
7. Attempted to enable replication from the primary host for a specific virtual machine
8. System defaulting to port 443 when HTTP (port 80) is explicitly selected.
9. Continuted with Use Kerberos authentication (HTTP) (port 443) is explicitly selected.

Error Observed: When configuring the connection parameters for replication, the default port is set to 443 (which is for HTTPS).

I manually updated it to 80 (as we are using HTTP). However, enabling replication fails with the attached error message (screenshot).

Questions:

1. Why is the system defaulting to port 443 when HTTP (port 80) is explicitly selected?
2. Is there a specific configuration required for Kerberos authentication between standalone servers?

Answer 1

Hi,

The replica server port field does not change automatically. You have to modify it manually when you change the authentication type.

If you want to use Kerberos in Hyper-V replication, a Kerberos Key Distribution Center (KDC) is required for authentication, which is integrated in a domain controller by default. Since your Hyper-V hosts are standalone servers, you can use certificate-based authentication (HTTPS). Or it's needed to set up a KDC yourself. You may check to see if there are third party solutions for that.
