Hyper-V Help

Hyper-V running on a Win10 Pro PC. Host and VM share the same NIC. Recently RDP stopped working to the VM. After someone tries to RDP in I have to force "Turn Off" the VM in the Hyper-V Management Console and then it allows me to connect via Hyper-V Manager until someone tries to RDP in to the VM again. VM locks up and have to "Turn Off" again. Tried removing and recreating the virtual switch and when I didn't that the VM allowed me to connect via HV Manager without having to hard power off. I've poked around the network settings on the VM and host and haven't been able to figure out what might be causing this lock up. Nothing jumps out at me from Eventvwr.

Anyone heard of something like this?

We have some 2012 R2 VM's (Hyper-V) we would like to move. They are currently located on a 2012 R2 server and are going to move to a 2016 server. 2012 R2 will continue to run on the VM's themselves. After we do some work on the physical 2012 R2 server, we are going to move them back to the 2012 R2 server. Is there any known issues in doing this for a live migration either to the 2016 or back to the 2012 R2 that we need to be aware of?

Hyper-v Guests sluggish, random disconnects, high cpu (after September 23rd, 2019 update)

Host: Windows 2016 Server Stnd
Guests: Windows 10 Pro (6 guests)
Ram (16GB Each)
Everything is up to date; windows patches, we have removed antivirus and security tools, we still have these random issues.
Users can connect, if they get disconnected (RDP) they cant connect and we have to reset the vm.

Can someone help me here? Please and thank you :P

Hello,

I have a stand alone Hyper-V server, VMs are located on a storage on a iSCSI shared disk.
Now I have another server to add as an Hyper-V new node, so the idea is to configure Hyper-V fail over cluster.

It's possible to "migrate/install" the actual stand alone Hyper-V production node to the new scenario using the same iSCSI shared disk ?

Can load the VMs load over the 2 nodes ?

Thanks.

Host OS - Server 2016 Standard with Hyper-V Role only.
Original VM - Windows 7 x86 Ultimate
Attempting to update to Windows 10 Pro Build 1903.
Host Server is a Dell ProLiant R430, single Xeon CPU 6GB RAM

I am attempting to upgrade a Windows 7 VM to Windows 10 and am getting the:
"this pc's processor doesn't support a critical feature (nx)"
error.
I have had a look throug the Host's BIOS and cannot find any mention of Execute Disable, DEP etc etc that I have found looking for similar issues regarding physical updates.
Any suggestions gratefully received as I am trying to avoid having to re-install all the existing Windows 7 applications.
The upgrade worked perfectly on a physical Windows 7 Workstation.
A clean install of a Windows 10 VM works OK.

Running Windows Server 2008 R2 as a Hyper-V host for a couple of VM Servers. For a new Backup scenario I need a program that will not work on 2008 R2. Can an 'in-place,' upgrade to Server 2016 be done? Will I need updated licenses to keep the two VM Servers I am currently using?

Hi All,
Previously I was assisted when I updated a Windows 7 Pro PC to Windows 10. On it was a Windows XP VM using the Microsoft VM kit. https://www.experts-exchange.com/questions/29158738/Windows-XP-VM-did-not-migrate-when-host-computer-was-upgraded-to-Windows-10.html (Thanks again for your help).

After migrating, I setup Hyper-V to be able to start the Win XP VM which has a new issue. It prompts to re-activate upon start-up. I am able to work around it for about 2-minute intervals before it locks and puts me at the Activate Windows screen. No big deal.

My primary issue is that I have a file that is on the Windows XP VM and I cannot copy it to the Host computer. I have tried Enable Guest Services, Enable Enhanced Services, etc but since it is Win XP that option is not recognized.

Any suggestions?

I just setup a 2019 standard server and created the first VM guest. When I go to connect to that guest in hyper-v manager, the display window is larger than the screen. Both the host and guest instance are set for 1024x768. I do not have the option to grab any of the borders of the window to drag and make the window smaller. This should be straight forward.

Hi Virtualization Experts

We have an old VMWare ESXi server running two Windows VMs (one running Windows server 2008 and the other running Windows 2012 server).

VMWare ESXi is version 5.1 and free license (I think).

I have a brand new server which is running Windows Server 2019 standard with Hyper-V role installed.

I need to convert the virtual machines on VMWare to Hyper-V machines.

The Microsoft Virtual Machine converter is a no go because ESXi is running free version 5.1.

Hyper-V host is Server 2019 standard edition.

Here is where I am right now.

1. The first VM has 4 disks as you can see in image one. VM Guest OS is Windows 2008 server.
2. All disks are set as SCSI on vmware end.
3. Exported VMware machines using the "export to OVF" method.
4. Converted VMDK files to VHDX file using Powershell command.
5. I created a new VM on Hyper-v with Gen1 format and attached 4 disk as scsi disks.
VM boots up to flashing cursor
6. Changed disk type to IDE and machine starts up but fails to boot into windows and goes to startup repair
Startup repair fails to fix the issue itself and goes into kind of recovery mode.
7. In this mode, it asks me to login with Administrator account to which I don't have pw since this is a domain controller and I don't know how to even set the password of local administrator account on a domain controller.

How do I fix this guys?

I have matched all the rest of the VM config i.e. the RAM, vCPUs etc.

Amazon Web Services

LVL 13

Are you thinking about creating an Amazon Web Services account for your business? Not sure where to start? In this course you’ll get an overview of the history of AWS and take a tour of their user interface.

MD3200 with most recent firmware being used in a two node Hyper-V cluster. The cluster is Windows Server 2019 Datacenter.

Here are my host mappings:

I need host HYPERV01 in the Default Group since, as you can see from the picture, all the virtual disks and so forth are mapped to the default group. I cannot at this time move storage from one hyper v node to the other. When right-clicking on Host HYPERV01 the move option is greyed out. Host HYPERV01 has only Virtual Disk Access mapped to it. I believe Access gets mapped to everything.

Question: How can I move Host HYPERV01 back into the Default Group?
End Goal: I need both hosts HYPERV01 and HYPERV02 able to access all storage.

Hi Experts,

I have a Windows Server 2016 setup with Hyper-V. On the server 2 virtual machines have been created. This has been a standard installation and the default Production Switch is used.

I would however like to give the 2 virtual machines machines a fixed IP (different from the IP they automatically received).

The information I see requires to setup a different virtual switch. Since the machines are in production I would like to be sure this is the correct procedure. Perhaps a link to the correct procedure?

Thanks for any help in advance,
Mark

Two node Hyper-V cluster. Both nodes are Windows Server 2019. All guests are Windows Server 2016 or higher.

I noticed that a few guests has checkpoints (snapshots) that were no longer needed to I attempted to merge them. I get this error:

I am logged on as the DOMAIN ADMINISTRATOR and still get that error. We need to merge these snapshots before they start taking up too much space. Ideas?

Hyper V question:

Basic setup:

I have two host machines - 15k drives / 32 threads / 128 GB RAM for RDS Farm

The way we have been setting these servers up is create VM1, VM2, VM3 on HOST 1 and VM4, VM5, VM6 on HOST2 and enabling local replication back to the other host. So VM1, VM2, VM3 has a replica on HOST2 and vice versa.

I also have two host machines with much more disk space that have 7.2k drives / 32 threads / 128 GB RAM for VM machines that aren't performance biased.

I'm wondering if it makes more sense from a performance standpoint not to cross replicate but to point the 15k hosts at the 7.2 host to store the replicas. Am I splitting hairs here?

Hi,

We are running exchange server 2016 in DAG setup. DAG is working fine. Databases are healthy.
I checked my exchange servers databases VHD's file size and notice that both servers databases VHD's size are not same. Please review the below image.
I checked database size in exchange servers and databases size are same on both server. Please review two images
Questions:
1. Why VHD's size are not same? Do i need to worry about it? There is no error related DAG in event viewer. Everything is working fine if server one is down than database move into 2nd server but I really need to know why different size of VHD's.
2. You can see that 'E16DB1_55A2801F_......AAD.avhdx' also taking so much disk space like 550GB. What's the purpose of avhdx? can we reduce the file size without damage anything.

I have just virtualized a Server2008R2 using DISK2VHD, which I have been using for decades without problems.
The Server2008R2 consists of a C drive, D drive + E drive.
After finishing I try to start this froma newly created VM om my Server2016 Hyper V host server.
HOWEVER start is failing due to boot error.
Can not find boot record.

I assume that the problem in fact is a simple boot order, but I dont know how to fix it.

When I look at hardware properties of the original Server2008 it says this:

Location 2 Bus 1 Target 0 LUN 0
Location 2 Bus 1 Target 1 LUN 0
Location 2 Bus 1 Target 2 LUN 0

I assume this is drive C D and E in order but Im not sure.
In the VM I have 2 IDE controllers both with 2 channels.
How do I set this up or does the problem lye in something else?

Please dont advise me to use other tools for virtulizations. I have used Disk2VHD for HUNDREDS of conversions without any problems :-)

Cluster nodes are Windows Server 2019 with the latest patches as of this post.
Guest is Windows Server 2016.

We have a two node-Hyper-V cluster. We were merging a rather large snapshot into one of the VM's (deleting a checkpoint).

The VM was on node A but node B owned the storage and network resources. Node B went offline because another engineer realized the IP address of the node was wrong so changed it without letting anyone know. The event log of the node the VM was on has the following:

* Event ID 19070 - Background disk merge has been started - this is when I started the disk merge.
* Event ID 19050 - VM failed to perform the operation. The virtual machine is not in a valid state to perform the operation - this is when we had the issue with node B.
* Event ID 16400 - VM cannot access the data folder of the virtual machine. - VM is down hard at this time.
* Event ID 19100 - The description for Event ID 19100 from source Microsoft-Windows-V-VMMS cannot be found. - When I saw this error, I about lost my lunch.
* Event ID 19070 - Background disk merge has been started - looks like the disk merge started up again.
* Event ID 19090 - VM background disk merge has been interrupted. - Ouch.
* Event ID 19070 - Background disk merge has been started - looks like the disk merge started up again.
* Event ID 19090 - VM background disk merge has been interrupted. - Getting nervous again.

Angular Fundamentals

LVL 13

Learn the fundamentals of Angular 2, a JavaScript framework for developing dynamic single page applications.

Here is the situation:
I recently purchased a Dell server that had Server 2019 Standard pre-installed. Now it is my understanding that I can install Hyper-V and have 1 "free" install of Server 2019 Standard as a VM.
Is that accurate?

If so, where do I obtain the actual product key from?

Thank you!!!

backup the hyper-V CentOS VM

hi,

we just setup CentOS VM using hyper V in windows 10 enterprise, and we try to avoid the situation which we mix up the existing VM, should we just create a snapshot of the existing CentOS VM ? this can make sure the current CentOS VM can restore back by this snapshot ?

then how can I create the snapshot?

New server for a site of approx. 30-35 users. Will be running 4-VM's in Hyper-V on W2K19 Server OS (VM's- DC/Print Server, Remote Desktop Server (minimal use), 2-Application servers). Possible future File VM (would need more MS licensing). Purchasing a new HPE DL380 Gen 10 Server as the Hyper-V Host. 2-processor (24-core), 128GB RAM, P816i-a SR Gen10 Controller with 16-open SFF slots. Thinking OBR RAID 10, (8) 600GB SAS 10K 12Gb/s drives plus (2) hot spare. Extra bays for future growth. Will have 1-Array with 2-logical drives- one for Host OS and one for the VM's. I am researching SSD options from HPE as well but looking to justify cost to owners.

Question- Should I be installing SSD in this configuration? Read, Write or Mixed use? Site typically runs servers 6-7+ years. SATA or SAS SSD (leaning towards SAS SSD if we go SSD route). Trying to justify the extra cost of the SSD setup. The SSD SAS 12GB/s option from HPE is pricey.

Thanks in advance for the input.

My goal: want to connect to my clients with a unique url for each client

am wondering if I can set a virtual PC in the cloud and with a VPN add it to my clients local network and then have a link to connect to the vm.

We have a single server that has four virtual machines on it. All 2016 Hyper-V. We are setting up a two node Hyper-V cluster. The cluster will comprise of:

* Two Dell R820 servers
* A MD3200 Direct Attach Storage unit.
* A MD1200 storage expansion unit.

One of the virtual machines is 1.5TB in size including snapshots.

What is the best way to move the VM's over to the cluster?

I was thinking:

* Stand up one R820
* Attach the MD3200 to that R820 and expose the virtual disk of the MD3200 as a shared E drive
* Export the VM from the current Hyper-V machine over to the shared drive
* Remove the share and remove the E drive from the R820.
* Stand up the cluster. The virtual disk of the MD3200 will then be found in the CLUSTERSTORAGE folder of both nodes.
* Import the virtual machine into the cluster.

What do you guys think?

Hi,

I d like to setup a Hyper-V with KVM (wont attach display or keyboard/mouse, the hardware will not be reachable physically once condigured, so need to have control as from boot) on a Intel NUC.
Preferrably 32 GB or more, will run lab environment (Windows domain, some test servers, some w10 machines) periodically but most of time do nothing so power usage is key.
Also has t to be latest top knodge performance, budget is important too (just a lab which I might shutdown/boot when needed/not needed). Have a Synology ds918+ that could run the vms or I run them locally and backup via Synology.

Please advise what hardware you would recommand. Would like to spend like 200 Euro max, if really worth it, budget is stretchable).
