Hi,
I couldn't see the Host Machine and VMs from the local Hyper-V manager after the HP System Management Homepage (SMH) software installation. I had removed the SMH and it's still unable to show them on the hyper-v manager.
However, I checked my vmms is running and i still able to access the virtual machine via Teamviewer (so, it's up and running).
Please help me on this issue.
Thanks,
Lizz
Hi,
We have a situation that we have to do the following:
Questions are:
To share more thought related to this scenario:
Any other points related to disk type, whatever configuration, supportability….? knowing that this will be temp scenario till they build Hyper-V 2019 at old site.

Hello everybody,
after diagnosing why every DPM 2019 I know of offers a bogus "Th-VM" VM when we configure Hyper-V RCT backups, Mike Jacquet asked me from this thead https://social.technet.microsoft.com/Forums/en-US/83718d47-9d4b-4579-a479-c1d96298b084/dpm-2019-insists-offering-nonexisting-vm-a-for-hyperv-host?forum=dpmhypervbackup in the DPM forum to post here. Mike found that it is Hyper-V which enlists a VM named "Th-VM". For details, please see the linked thread.
What can we do about this?
Best Regards, Stefan Falk
This is a fairly simple question, and I'm hoping the answer is fairly simple too.
I have a straightforward 3-node failover cluster: the servers are running WS2019, and the 30+ VMs are running a mixture of Windows Server, Red Hat Enterprise Linux, and Ubuntu.
The Linux servers live-migrate flawlessly.
The Windows servers will NOT live-migrate; they throw a 1155 error.
Any thoughts?
Thanks!

I have been rolling out Hyper-V hosts and creating Hyper-V VM's for quite a while now. Everything fine, until this case. I need some greater minds to shed some light on this.
I need to convert a running Windows 2008 R2 server with 8 GB RAM into a Hyper-V VM. We need this machine so we can run a specific old software (from time to time), and the physical machine is acting up. My Hyper-V host runs Windows 2019 Hyper-V host, has enough physical RAM (16 GB). It has been used to create and run all kinds of VM's (Windows 2008 server --> Windows 2019 server), Windows 10 etc.. Never failed. RAID 10 on harddisks and enough room.
I have tried a few ways to create the VHD file for this runing server. Straight from the server with disk2vhd, and from system recovery backups created by Veritas Back-up Exec System Recovery (tried a few version of the software). My VHD's contain all the files I see on the real server, and the real server has only one partition. No hidden partition (checked with diskpart).
The VM I create has the same amount of RAM as the real one, Generation 1. When I attach an iso to it, with the Windows 2008 R2 boot disk, it boots just as expected. One I attach the VHD to it, it never boots. Black screen, blinking cursor (if the VHD is
the first boot drive), sentence showing I need to push any key to start booting from DVD if the DVD is the first boot device. But the VM does not boot. Once I disconnect the VHD, the same VM boots fine.
Tried creating a blank VHD for the same VM: VM boots fine.
I have never has this experience with Hyper-V and none of my Google searches bring this scenario up. Any ideas?
Next up I will try a competitive system to boot the VHD.
Kind regards,

I have written my own OS to detect how many drives present on my computer. But I had some difficulties with hyper-v. I found that I added the DVD disk in hyper-v. However, when I was brutal forcefully probing how many disks exist. It turns out that the DVD disk is not present.
The same problem is with ReactOS. When ReactOS tries to fetch first several bits from the CD disk by using ATA, it runs into the issue of IO1_INITIALIZATION_FAILED.
Here is my configuration:
IDE 0: CD myos.iso, Drive testvm.vhd
Here is the number of devices that I have on this virtual machine:
disk number: 0x0 (floppy disk 1)
disk number: 0x1 (floppy disk 2)
disk number: 0x80 (hard drive)
If it's correctly running, it should show another drive with number 0xE0. I have tested this on Qemu, it turns out to be correct. However, I do not know why it does not work on hyper-V. I will test VirtualBox next. My guess would be that hyper-v has some protection mechanism to prevent a CD being written. But it does not exempt a disk being not present in the system.
We are setting up a Windows 2019 Hyper-V VM running on a Physical Windows 2019 Server with 64GB of Ram. The Physical server will be running a few lightweight apps and also the Hyper V roles. I have been reading up on Dynamic V's Static memory allocation for the Hyper-V server and cannot decide which option is better. As I see it I have 2 ways I could go -
1. Allot 32GB of static ram to the Windows 2019 Hyper-V VM
2. Enable Dymanic Ram Set 8GB of Ram as a minimum Value, Set the Max Ram to 32GB with a 20% Memory buffer
We are planning to use the Hyper V for lightweight Remote desktop use.
What I am wondering is, does having Dynamic Memory instead of static cause speed issues for the VM when the amount of RAM required has to be increased or is this so fast that it is not noticeable.
Any thoughts would be appreciated
On surface pro 7 I need HyperV to run a win10 32 bits on the basic win 10 64 bits pro
I uploaded an official win 10 32 bits
I created an Hyper V using this .iso
I started the machine as requested.
It stops on:
"start PXE over IPV4
VM boot summary
1. SCSI DVD did not load an OS
2. SCSI disk idem
*3. Network adapter (00155D00AA03)
No operating system was loaded.
Your VM may be configured incorrectly"
The VM does not see the .iso or the .iso has not the right format.
Would you know what should be changed?
Thanks a lot
Hello Team,
We want to explore in Hyper-V replication on Advanced level. Following are the question::
1) As we have option of selecting recovery point in Azure VM replication can do we same on-premise Hyper-V replication
2) Can we monitor Hyper-V replication at granular level where we can see our which last replication point was successful.
3) Even after VM failover can we able see which are best replication point we have.
Would like to know is it possible on on-premise Hyper-V replication. If Yes would like to have steps or free tools to achieve it.
Regards
Kedar
Hello,
I have a 4 node Hyper-V 2019 cluster running a decent number of VMs.
When trying to remove some snapshots that Hyper-V left behind from a backup I get the following error:
Deleting 'SNAPSHOTNAME - (M/D/YYYY - 8:18:20 PM)' failed. The operation cannot be performed while the object is in its current state. + CategoryInfo : InvalidOperation: (:) [Remove-VMSnapshot], VirtualizationException + FullyQualifiedErrorId : InvalidState,Microsoft.HyperV.PowerShell.Commands.RemoveVMSnapshot + PSComputerName : HOST
Searching online the only help I found was to create a new snapshot and then export the VM from that. Then delete the original and import the exported copy. I would prefer to avoid that if possible as some of these VMs are quite large. They are still operational just cannot clean up these specific snapshots. I was able to remove a bunch of standard non-recovery snapshots without any issues.
#LnQ¯\_(ツ)_/¯
I create a new virtual disk and choose to copy the contents of the physical disk and get an error.

Failed to convert the virtual disk.
While trying to install the update KB4057903 - Hyper-V integration components, the server freezes after restart on the screen "Getting Windows Ready" for about 15minutes. After that the server gets almost unresponsive.
Managed to restart the vm via safe mode and stopped the update, but how can i install the update? What causes the problem? I had no problem with the other updates of January 2018. Error Details: 800F9023. In HYPER-V VM enviroment.
It is also the exchange server and i have stopped all Microsoft Exchange Services.
Hi,
We're running 2016 (2 hosts in a cluster) on the hosts with some 2008 R2 and 2012 R2 guests. One of the 2012 R2 guests gets stuck on 'Please wait...' during boot up and never comes up.
I need to boot this VM in to safe mode but no matter what I try I never get the boot options menu appear. Turning off the machine while running does not even force the boot menu, which it does in 2008 R2.
How do you perform this simplest of tasks in Hyper-V on 2012 R2 guests?
Thanks
Ok, I've wasted an entire day searching for an answer for this. I found a few people with the same issue but no answers.
I built a Win10 1607 Gen2 VM. I mounted an ISO to capture windows for SCCM. I cant change my boot settings in Firmware because they are missing.
I went to the CLI in PS and tried Set-VMFirmware -VMName 1607 -BootOrder "DVDDrive","HardDiskDrive"
Set-VMFirmware : Cannot bind parameter 'BootOrder'. Cannot convert the "DVDDrive" value of type "System.String" to

Has something change in the was this is done? I have 5 Hypervisors all running the same build and none of the gen 2 machines have this option. The Gen1 VM's are fine.

I have 2 host HyperV which configure in cluster. Inside the host there are multiple virtual machine. When I try to create new virtual machine usung Generation 2, its firmware boot order shows " No boot entries are configure". How to solve this issues without break the failover cluster configuration? For your information, all virtual machine inside the host are production.

Hi,
I have following issue: I'm not able to change generation 2 vm's boot order. Neither Hyper-V Manager nor Powershell can do it:
On good host (all settings are correct):

Both servers are Windows 2012 R2 with all updates installed. I have found this thread: https://social.technet.microsoft.com/Forums/office/en-US/d1a5238e-b20f-4773-9ad6-253cae118f10/uefi-boot-order-options-missing-from-hyperv-host?forum=winserverhyperv but I cannot reinstall Hyper-V role (server is a part of production environment). Do you know how to fix this issue?
I need help connecting to Windows server core 2019, I currently have Hyper-v core 2019 installed on a dell server, then install the windows admin center tool on another computer, using Windows 10 , when running the windows admin center application to connect to hyper-v core, the following error message
"WinRM cannot complete the operation. Verify that the specified computer name is valid, that the computer is accessible over the network, and that a firewall exception for the WinRM service is enabled and allows access from this computer. By default, the WinRM firewall exception for public profiles limits access to remote computers within the same local subnet.
Thanks for your support
