Microsoft 2016 & 2018 DataCenter Hyper-V Inventory tool ??

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

Hyper-V 2016 Replication

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?

Is it better to create a 2nd volume on a Hyper-v cluster or expand Volume 1?

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.

Hyper-V virtual switch(es) export then import

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

Hyper-V reverse replication fails

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?

HPE Gen9 and Gen10 mix in cluster

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

avhdx leftover from backup tool – how to merge or delete those files?

I’ve dome some tests with a 3rd party backup tool for Hyper-V. Unfortunately it does not work as expected. I removed it from the system. 

Now I have a differential avhdx and corresponding *vhdx.mrt and *vhdx.rct files sitting around, for each virtual disk. 

The avhdx is not visible in the hyper-v GUI as a snapshot (I did not create snapshots), and also
Get-VMSnapshot will not show it at all (thus Remove-VMSnapshot won’t work). I only see them in the filesystem.

That would not bother me so much, but a side effect is that normal snapshots do seem to fail now.

I tried to merge the avhdx into the main vhdx with "manage disk" in the hyper-v GUI, but the
ID is not matching and I am not sure if and how to proceed. The GUI warns that there might be data loss. 

How do I get rid of the .avhdx, .mrt and .rct files? As I mentioned, the usual way to merge snapshots does not seem to work. 

Any pointer is very welcome. 

Thanks

Hyper-V encountered an error trying to access an object…

I’ve Googled this issue on and off for most of the day, more or less attempting every potential fix in the hope of resolving this issue so that I can move on and deploy a bunch of servers via Docker.  I’ve so far being unsuccessful.

Earlier today I installed Hyper-V.  Simple enough (and throughout my attempts to get it to work I’ve uninstalled, reinstalled, purged and re-imaged OS backups countless times).  Then I threw Docker into the mix.  Docker complained with the
noted error, so during my attempts to resolve it I ended up where I started: a recent OS image and a fresh install of Hyper-V.

When I attempt to use Hyper-V Manager, the issue is highlighted further because most entries within Hyper-V Settings, under Server, such as Virtual Hard Disks, Virtual Machines, NUMA Spanning and Enchanced Session Mode Policy list "Load Failed"
as the only item, with the error "There was an error loading the data for this setting." explaining how Hyper-V encountered an error trying to access an object…

The same goes with the Global Network Settings, under Mac Address Range, where "Load Failed" rears its ugly head again.  To cap it all, the Hyper-V Quick Create app throws the error the moment it starts.

No matter what I have attempted today, I simply cannot get Hyper-V working, and I’ve tried every solution Google has thrown at me.  Therefore I’d be eternally greatful for any assistance resolving the issue.

Thanks.

The dynamic memory balancer could not add memory to the virtual machine Event ID 10020

Anyone knows how to fix this bug?

This happens on alot of our VM’s running a 2016 Hyper-V Cluster - hardware is HPE BL460c G9.
