Hyper-V failed to enable replication relationship on the Replica server: Unspecified error (0x80004005).

Event IDs on B2

Event ID 16300 Cannot load a virtual machine configuration: Unspecified error (0x80004005). (Virtual machine ID A10F389C-C365-4829-A748-36EAA9009690)

Hyper-V failed to enable replication for virtual machine ‘VMNAME: Unspecified error (0x80004005). (Virtual machine ID A10F389C-C365-4829-A748-36EAA9009690)

This only happens to some VMs, those that previously used Certificate based replication.

  1. Domain A VMs are replicated to Domain B via certificate based replication.
  2. Domain A servers are running Hyper-V Server 2012R2 or 2016.
  3. VM version is 5.
  4. VM is failed over to Domain B Hyper-V replica server B1 running WS2019 Datacenter host and started, no errors.
  5. VM is replicated to a different WS2019 Datacenter host B2 in Domain B and is failed over.  It’s still using certificate based replication.
  6. Replication is removed on all hosts.
  7. VM is deleted on but B2.
  8. VM is shutdown and upgraded to version 9.  VM starts and works fine.
  9. VM is deleted from B1.
  10. Enable replication fails from B2 to B1 with errors above.
  11. I can create new VMs on B2 and replicate them with or without certificate based replication without error.
  12. I have searched and removed all files/folders with A10F389C-C365-4829-A748-36EAA9009690 in their name on B1.
  13. Where is B1 still storing information about A10F389C-C365-4829-A748-36EAA9009690?

Remove Cluster Volume 1 from Failover Cluster

Hi All,

I have a simple question that Google nor Bing can definitively answer. I have a cluster with 3 storage devices, Cluster Volume 1, 2 and 3.  I wan’t to remove Cluster Volume 1. There is no data on that volume, so not worried about retaining any data.
If I remove the volume from the cluster, do Volumes 2 & 3 stay at  2 & 3, which I would assume is the proper behaviour. I just want to make sure that the system doesn’t reshuffle the volume numbers and cause all my vm’s to go offline.

Ok, so this is a 2 part question. Say I want to add another volume later, will that become Volume 1 or 4?

Thanks in advance.

Server 2008 R2 Missing VSS and VDS services after converting to Hyper-v 2012 R2

Hi All,

Good day.

Will need some help on this, recently had converted my domain controller from VM ESxi5 to Hyper-v 2012 R2 host.

My domain controller runs in window 2008 R2.

The server is able to power on after the conversion, but only issue is i am unable to run disk management. Also the Virtual Disk Services (VDS) and volume shadow copy services (VSS), is no long listed on services.msc and i am not able to turn it on.

Is there anyway or how could i fix this issue? As my backup required VSS and VDS to work.

Failover cluster manager networks

I have created a Windows 2016 hyper-v failover cluster with 2 no hypervisors (soon to be 3) and a NAS for storage. 

Each hypervisor has 4 NICs so I used 2 of the NICs for MPIO iSCSI and the other 2 NICs I created an LACP team to our Cisco switches.  I have one external vswitch that is configured with the team logical adapter. 

The team is also a trunk link so I can pass mutiple vlans on it and it currently has a management vlan for the hypervisor physical IPs and a client traffic vlan,  see pics below - 

So my questions are - 

1) Is what I have enough for it to work properly or should I be looking to have additional networks for live migration, cluster communication etc. 

2) If I do need extra networks how exactly do I go about creating them ie. I can add any number of vlans I want to the team/virtual switch but how do I then get FCM to see and use them. 

3) If 2) can I add additional networks without any downtime or at least one hypervisor at a time so I can drain roles to the other etc. 

I have a horrible feeling I may need to rebuild the cluster to get this setup optimally. 

Any pointers would be much appreciated.

If stop vm on one cluster manually move files and start vm works correctly.

Datacenter upgrade woes.

Hi all,

 

I am having a nightmare with a DC upgrade. We currently have a 2012 R2 Standard running hypervisor services. To get more out of the box we ordered a DC licence. I have access to the Microsoft licencing site and have got a copy of what I believe to be our
key but I cannot get the OS to accept this and upgrade to DC.

 

So - several questions…

 

Can I upgrade from standard to DC with the appropriate key? I did specifically ask for this when we went through the quote process and was informed that the keys we would be provided with will be suitable to do an upgrade without rebuilding our hpervisor.

 

The error I am getting is

Error: 0xC004F050 The Software Licensing Service reported that the product key is invalid

 

The key I am using is from the micorsoft site - the section is

“Windows  Server 2012 Datacenter”

I have used the KMS key and in the web site it does show our company name as the organisation so I guess that means we are all paid etc.

 

I did check in the KMS server and nothing seems to have been registered in there (not sure what I was expecting but it wasn’t nothing) As an extra bit of fun out network is largly behind a firewall with no internet access but I do know that the KMS server
is allowed thorough and this is working - last contact reported was only a few days ago.

 

So - can anyone point me in the direction of installing the key and getting this OS upgraded if

cscript c:windowssystem32slmgr.vbs -ipk xxxxx-xxxxx-xxxxx-xxxxx

is not going to work?

 

Thank you

Kevin.

Hyper-V manager – black screens between Basic and Enhanced sessions

Hi all,

This seems like a common problem on the internet but I haven’t found a definitive solution anywhere.

Sometimes when booting up a Windows 10 VM, it will boot to a black screen in either a Basic or Enhanced session.

When I switch from the one to the other magically I can see that the VM has indeeded booted. The mere switching between the session types (Basic to Enhanced or vice versa) fixed the problem.

Obviously however it would be nice to not have to do this.

Does anyone know of the reason why this occurs and how to fix it once and for all? 🙂 

I am using the latest HyperV manager with the latest graphics drivers.
