I have made a standalone installation of Hyper-V 2019 on a powerfull HP computer for test propose for some projects.
I think I have done every thing I could read about to get Hyper-V Manager to
Connect with the server with Window 10 Pro. But I still get “illegal

what ever I do. Remote desktop works. I have done it before with Hyper-V 2012. It was not easy, but I worked. I need a precise
work around who

How to do a snapshot/checkpoint for a limited set of resources – i.e. only for a single volume

How to do a snapshot/checkpoint for a limited set of resources - i.e. only for a single volume

O know, this is weird, but let em explain!

A developer has a Server with 2 volumes, C: and D:

Windows at C: and an application server at D:

Developers are doing a special trya-and-error upgrade on lab and they´re asking to do a snapshot only for D: volume, not for C:, i can throw away c: drive and re-install windows from scratch, but preserving the D: volume, becuase over time they change things,
sum up things

So, the idea is to do a snaphost/checkpoint, but limited to drie c:, goping back in time ONLY for Drive C:, but preserving the D: Drive

It´s possible? If so how?

10 minute wait for network after live migration

Hello

I have a three node failover cluster.  Two nodes are local, and connected to the same SAN.  The other node is at a remote location connected to a different SAN that is a mirror of the local SAN, over a 1Gb E-Line connection.

When I live migrate a role between the two local nodes everything is fine.  When I migrate a role from the remote node to a local node, everything is fine.  When I migrate a role from a local node to the remote node, the migration takes the expected
amount of time but once the migration is complete, it takes about ten more minutes for the network to come up.

I have disabled encryption on the E-Line for testing purposes and it didn’t help.

I can connect to the role via the console while it is in this no network state and Windows says that it is connected to my network but the connection is limited.  I can ping the network adapter but cannot ping the gateway.

Has anyone else seen symptoms like this before?

Hyper-V 2016 Cluster – Network Config

Hi there,

I have successfully configured the Hyper-v cluster but I realized after that I need to configure more cluster networks. Specially, I want to add another network for Live Migration. I can’t seem to figure out how to configure additional cluster networks.
I can see available network interfaces but can’t see how to add more cluster network to utilize those available NIC’s.

Can someone explain what I am missing here?

Thank you.

Max Processors on Server 2019 VM

I just purchased a new HP Proliant DL360 GEN10.  It has (2) 16 core processors.

This server will be a dedicated Hyper-V HOST running Server 2019 STD, for a mission critical SQL database VM running Server 2019 STD.

My question is what is the maximum amount of processors I can assign the VM?  I would like to have as much processing power as possible.

I have allocated 352GB of RAM to the VM. Total RAM on the HOST is 384GBs.

Attached are the current settings of the VM.  Any recommendations on how to optimize performance would be appreciated.

Windows Server 2019 locks up during boot after hypervisorrootproc is set

I’ve used bcdedit /set hypervisorrootproc to limit the number of cores the host OS can use on windows server 2016 for all my hyper-v servers.  This helps free up processor resources to be used by guests.  The initial couple of server 2019 servers
(i’m using for hyper-v hosts) that I’ve set hypervisorrootproc to limit cores lockup at boot and will never boot normally again until I go into safe mode and give the OS access to all cores.  Has anyone experienced this yet?  I haven’t had time to
troubleshoot if it is specific to limiting to 2 cores vs 3 or 4 or if I limit cores at all.

ReIP VM’s over the network with Powershell

Hi Experts,



We have a requirement here to re IP all our VM’s as we are moving to a new data center.



While trying to do so, I found a very good script from vmnomad.blogspot.com which I later customized to our need.



Script is running fine with the required parameters & updates, but its not able to change the IP address, though it says, it changed the
IP address.




Command syntax from PowerCLI: NewreIP1.ps1 -Inventory .Test-Inventory5.csv -VC vCenter

Initially we had issues running the command:

his command syntax invoke-vmscript -ScriptText $changingIp -ScriptType bat -VM $vm.ServerName -GuestUser $vm.Username -GuestPassword $vm.Password
using ‘netsh.exe in the guest VM.

Later on its found that the script runs perfectly if we disable UAC for our test VM’s.

With UAC enabled, it cannot run.

We need to disable UAC for 300 plus VM’s & if we do so, we need to restart as well, which is not possible in one go.

Is there a way to disable UAC for all the VM’s & run something like ‘net stop server && net start server 
& avoid restart through Power shell or by any means?

Please let me know, that would be very helpful.

Thanks

WS 2003 VM network only working in safe mode with networking

Hello!

I’m working on making a virtual lab enviroment in Hyper-V to test the upcoming AD/EXCH changes we plan in our corporation.

I’have successfully recovered 2 WS 2012 R2 server with BMR (gen2 vm). They communicate and replicate nicely.

My problem is when I recover my WS 2003 DC (gen1) it can only communicate on the network if I start it in Safe mode with networking. In normal boot mode it registers itself on the network, but after a couple seconds no packets can be sent in either direction.
The NIC says connected, but the traffic is not growing and I cant even ping other devices.

I have installed the Hyper-V Integration services on the machine. I’ve reseted winsock, TCP/IP stack and ipconfiguration. Still only functions in safe mode.

Can someone assist me with my situation?

Thank you,

PG
