It’s been a while I played around with Virtual PC/Server as it was called in the day. It’s Hyper-V now and that’s what I want to use to get two VM’s running as a replacement for two SBS 2011 servers. So we bought a fairly ‘fat’ server - a Dell Poweredge
R7415, sporting an AMD Epyc 7281, 64 GB RAM, BOSS-card (240 GB configured in RAID1), three 960 GB SSD’s configured in RAID5, six 2 TB near-line SAS drives configured in RAID5 and four 1 Gbit network adapters.

What we need is a fileserver/domain controller and Exchange server. So we bought Windows Server 2016 and Exchange 2016. Windows Core is to be installed on the BOSS-card. The virtual domain controller / file server uses the near-line SAS drives to store it’s
virtual disk. The virtual Exchange server uses the SSD’s to store it’s virtual disk.

Installing Hyper-V is pretty much a no-brainer. As is creating a new VM. But both VM’s and the host have to be configured for optimal performance. So I read the MS documentation for Hyper-V, but can’t find anything about recommended configurations. I broadened
the search to the internet, but that’s no luck either. Tons of websites describing how to install Hyper-V and create VM’s but there it stops.

Could be I searched the wrong way, so please point me in the right direction. Or maybe recommend how to configure both VM’s like how many RAM I should allocate, what to do with the network settings - do I tie them all to the virtual switch or do bind them
directly to the VM’s etc.

Hi,

I have windows 10 pro 64bit OS , hyper V addon enabled. 

I created a virtual pc on my windows 10 machine, I am starting the machine but unable to connect to it. 

I am not getting error.

do you guys/gals have an idea ? 

troubleshooting steps that I took are;

confirmed virtual is enabled in bios,

I launched the hyper v manager as the user or as administrator still unable to connect to it.

Hello.

Before writing I have read hundreds of posts, articles, … and I have enabled all the permissions/parameters to permit the connection without domain.

I have installed an Hyper-V 2019 Core Cluster Workgroup (without domain): it functions perfectly.

I can connect to the nodes with Hyper-V Manager from my PC (in domain).

But when I try to connect to the cluster with Failover Cluster Manager:

• the name in the tree has a red down arrow
• the cluster status is "Down"
• the cluster service status is "Running" for all nodes

If I run a Validation Test, I have the following error: "List Disks" failed with "The remote procedure call failed" and in the Event Viewer I have the error 81 "LogExtendedErrorInformation (974): Extended RPC error information:".

Thank you in advance for your support.

Best.
Alessandro

Hello!

We have transfered our Exchange-Server from a 2008 R2 Hyper-V to a 2016 Hyper-V.

The VM has a very big and old Snapshot. We tried first to merge the Snapshot on the 2008 HyperV but

this was impossible. So we transfered the VM To the new Hyper-V. After the Transfer the Merge started automaticly.

Our Problem is, that the Merge take a lot of Performance, so that our Servers are running but with a very bad performance.

My Question: Does anybody know what the VM will do when i abort the Merge.

Will it stop and i can restart it later. Or will it ruin my complete Config?

Regards

Andreas

Hi,

I have three virtual machines (Windows 10, Windows Server 2016 as a DC, Windows Server 2016 as a Router) in Hyper-V server. My problem is that I cannot ping the client and dc from the router and vice versa. Here are my
Hyper-V settings:

I’ve turned off the firewalls for all VMs.

Thanks for your answers

Hello everyone, 

I need to find out with you guys if its possible to run 2 Hyper-V environments in the same LAN, the LAN runs 1 hardware cluster and 2 more hardware servers. If so, are there any risks? Also, I like your suggestions on a hardware compatibility software that
I can test if my hardware is suitable running Win Server 2019. 

Many thanks for your help.

Server 2012

Pretty sure I had the Hyper-v role installed on my server.

Last night I installed the Active Directory Services role. On reboot, neither role is installed. Not sure what happened, but maybe someone can comment.

ALSO…

What is the preferred arrangement:

1. Hyper-v and DC running on same local host

2. Hyper-v with DC running on VM

3. Separate DC on designated physical server

4. Other best practice

My intention is to use the hyper-v manager server for virtual environments;  to help with application development on different server environments. I want a Domain Controller because I need a practice environment for testing domain services.

Regards,

Hello!

I’m trying to implement fast backup tool for Windows Server 2016+ Hyper-V (configuration 8+). I am using  C++ COM WMI. I was able to successfully create a snapshot and wait for Job is done but get in trouble to convert it to ReferencePoint.
For this purpose I use  ROOTvirtualizationv2 namespace, ConvertToReferencePoint method of the Msvm_VirtualSystemSnapshotService class. Incoming parameters field with: AffectedSnapshot contains __PATH of Msvm_VirtualSystemSettingData (Checkpoint
settings for the virtual machine.), ReferencePointSettings left empty because it noted in docs as optional. After method executing new Job not created (Job out param) is null and ReturnValue  is 32770 (vendor specific range). 

What am I doing wrong?

My PC/Host Machine:

• PC
• Windows 10 PRO
• 64GB
• Xeon Processor
• Quadro 9000
• Dinky Little Thumb Driver Wifi Adapter

The VM:

• 8GB RAM
• 4 Virtual Processors
• Hardware Acceleration > Virtual Machine Queue: Set to Off/Disabled
• Windows Server 2012 R2

All setup on my local PC, no external networking should be required. When I connect to the VM thru the Hypervisor RDP window or via Teamviewer, my Oracle database queries are nice and fast.

However when I do those same queries from the host machine, they tend to run slow at first, like if the device has been sitting a while. They sometimes get fast too… the speed measurement seems to putter like a muffler or something. Sometimes its
way to slow, like 2 minutes to retrieve 10 simple database rows… I’ve tested on the VM and on the host machine the same query simultaneously, the VM is less than .1 seconds to respond, the host machine is long, minutes.

VQM seemed like the most likely cause so I disabled it. The interwebs also recommended disabling it on the physical network adapter, but the setting is found there on this dinky little USB Wifi Adapter.

Any help is appreciated

Hello,

I am running Server 2016 Standard.

The Server is a member of a domain

I’m logged in with a Domain Admin account

I am unable to connect to the VM that I have created. I have tried both Gen1 and Gen2 VM. I have tried restarting the host.

The VM (Gen1) is reported as ‘running’ and in the preview screen I can see the initial dialog box for Windows setup, but I cannot connect to the VM.

This is really annoying.

I’ve spent some time trying to find an answer - and so far found nothing that works. Some one said removing McAfee worked for them, I only have the Windows firewall installed. There is very little 3rd party applications on the server at this point.

Would appreciate troubleshooting suggestions

Thanks

VW
