How I can rebuild assemblies for HyperV plugin in ServerManager ? 

Is it possible to do some kind of cleanup, and get a chance of stable execution for ServerManager ?

In the hyper V manager the Exchange server hosted on a VM reads the status as Turning off…

The server has been read this for a days now and has not shut down and is continuing to run as normal. Why would the status read this if it is not shutting down.

Is there a good inventory tool or add-on that can report on the

Virtual and Physical Servers ??  I’ve tried several from google searches

"xiaconfigurationserver"   and  Get-HyperVInventory-v2.4 scripts - not working ….

Is there a Microsoft Solution for getting a full inventory of what is running on Hyper-V ?

Thanks in advance

Hi guys,

I have successfully created a Hyper-v cluster with 2 host, 12 VM roles, each with it’s CSV on share HPE MSA 2052 storage.

I am to create a DR cluster with similar hardware, and not sure how to about the DR setup. Haven’t been able to find any step by step guide on how to do this.

Should I create similar CSV, then use a hyper-v broker to point to them as destinations for each VMs?

I have a 4tb volume 1 mirrored and am running out of space - no unallocated.  However, there is space in the pool.  I could expand the volume 1 or create a second volume (the way I understand it) and move vm’s to that volume.  Is there any
advantage in creating a second volume?  Would it be faster for vm’s to be in a smaller volume?  I have a software raid so I’m looking for any increase in speed I can get.

Hi,

We’re doing some Windows Server 2012R2 Hyper-V migration to Windows Server 2016 Hyper-V. I would like to check if there’s a way (PowerShell cmdlet/script or something else) that can export Hyper-V cluster virtual switch(es) into a file that can also be imported
to a newly built Hyper-V cluster? Better yet, if there’s a way to export the current cluster config and import to the newly built cluster?

Thank you

Hi,

I setup two hosts with Server 2019 and enabled certificate based replication on both.

Failover between primary and secondary host works fine. However when I reverse the replication I get this error message:

Hyper-V could not replicate changes for virtual machine ‘Lubuntu_test’ as Hyper-V is not in a state to accept replication on the Replica server. 

I have to remove the entire VM on the primary in order to have it succeed. This causes a lot of wasted bandwidth.

Both servers are in a different datacenter. I forwarded port 443 in the firewall.

If I create a new replication from secondary to primary host, it works fine.

What gives?

Hi,

I currently have 2-nodes Hyper-V cluster running on HPE Gen9 hardware. We have 2 new HPE Gen10 servers - can I join these 2 Gen10 server to the existing Gen9 cluster? All 4 servers are running the same Windows Server 2016 Standard version and build.

Thank you
