VMM Tricks: VM Migration failed with Error (2912): An internal error has occurred trying to contact an agent on ServerFQDN

Symptom :

When you try to migrate a VM between two Hyper-V hosts using VMM, it fails with

“Error (2912): An internal error has occurred trying to contact an agent on the Server FQDN. (Element not found (0x80070490))”.

 


Description:

“0x80070490” means “Element not found” and “Certificate not found”. This issue may be caused by a problem with the Host certificate (incorrect name, IP instead of FQDN or NetBIOS) or the certificate is missing from the VMM server.


Resolution:

The possible solution is to remove the managed host from the VMM server and also delete any residual certificates from the host on the VMM server, and then re-add the host. use the following steps:

1. On the SCVMM server, remove the managed host from the console. The steps on how to remove a managed host are outlined in the following TechNet article:

2. Locate, backup, and delete any certificates for the Host computer.

A. Open the Certificate console on the SCVMM server.

  • Open a new mmc and add the certificates snap-in.
  • Select the option of ‘computer account’ and ‘local computer’.
  • Select Finish and Ok to load the snap-in.

B. The certificates for the Host computer can be in any of the following locations.

I. Personal Certificates.

II. Trusted People (if the host is W2K8).

III. Trusted Root Authorities (If the host is W2K3).

C. In each store, expand the Friendly Name field and locate the certificate[s] for the Host server that have a Friendly Name starting with ‘SCVMM_CERTIFICATE_KEY_CONTAINER’ followed by either the FQDN / IP address / NetBIOS name of the Host server and delete them.

3. Re-add the host in SCVMM which recreates the certificates as needed.
