Hi ,
I have a windows 10 VM running on a Host ( Windows 2016 )
The VM has integration services installed and works fine , but when I enable the nested virtualization for the VM I am unable to use the mice
The error message is "mice not captured" but the intergration services are there ?
we need the nested V feature to run docker inside the VM
thank you in advance , any help would be appreciated
Hyper-V Host is Server 2016, VM is Server 2016, when attempting a production checkpoint I get the following:
'VM' could not initiate a checkpoint operation: Element not found. (0x80070490). (Virtual machine ID E397EC81-9B8C-435F-95C9-F9950638BF28)
Production Checkpoint for VM 'VM' failed in the guest VSS Integration Component with error Element not found. (0x80070490). If you continue to see this problem please use regular checkpoints instead (Virtual machine ID E397EC81-9B8C-435F-95C9-F9950638BF28)
I have two Server 2016 Hyper-V hosts, and each one Server 2016 VMs, on one host my backup software which requires production checkpoints for application aware processing works just fine, on the other I get this error.
The difference is that prior to installing my backup software, on the host with the error I created a production checkpoint, then deleted the checkpoint subtree. Even after removing my backup software I still cannot create a production checkpoint, I get the same error, on the host that works just fine, I never did the production checkpoint / subtree delete.
The production checkpoint / subtree delete seems to be what causes the issue, after testing on test VMs.
All VSS writers on host and VM are stable and not in error, reboot of the VM and/or host do not correct the issue.
Hi, My Hyper-V 2016 replication state error. i think this happened after the electricity off during night time and the host went down.
Pls help how can i fix it?
Hello.
I have several standalone Hyper-V Server 2016 hosts. All hosts are configured for live migration using constrained delegation and Kerberos (as detailed here https://docs.microsoft.com/en-us/windows-server/virtualization/hyper-v/deploy/set-up-hosts-for-live-migration-without-failover-clustering).
The problem is despite these settings (LM enabled, LM network set, Kerberos protocol configured, constrained delegation configured), when I initiate the migration using Hyper-V manager or Powershell from a management computer, this fails with the dreaded error (below). However when I initiate migration directly from the source Hyper-V host (using Powershell as there's no GUI), the migration successfully proceeds.
The management server is in the same domain and I'm logged on as domain admin.
The error is:
There are events on the source hosts:
Event 20308, Hyper-V-VMMS: "Failed to authenticate the connection at the source host: no suitable credentials available."
Event 20306, Hyper-V-VMMS: "The Virtual Machine Management Service failed to establish a connection for a Virtual Machine migration with host '<destination_host_FQDN>': No credentials are available in the security package (0x8009030E)."
Event 21024, Hyper-V-VMMS: "Virtual machine migration operation for '<VM_name>' failed at migration source '<source_host_netbios_name>'. (Virtual machine ID 2CF6050E-A08A-4B0C-A321-648AF12517B4)"
Events on the destination host:
Event 22040, Hyper-V-VMMS: "Failed to receive data for a Virtual Machine migration: An existing connection was forcibly closed by the remote host. (0x80072746)."
Event 20402, Hyper-V-VMMS: "The Virtual Machine Management Service failed to authenticate the connection for a Virtual Machine migration at the destination host: An existing connection was forcibly closed by the remote host. (0x80072746)."
Event 20400, Hyper-V-VMMS: "The Virtual Machine Management Service blocked a connection request for a Virtual Machine migration from client address '192.168.30.7': An existing connection was forcibly closed by the remote host. (0x80072746)."
Here's a screenshot of constrained delegation configuration of one of the hosts, the configuration is identical on all hosts, ie. cifs and Microsoft Virtual System Migration Service allowed for all other Hyper-V hosts.
Any help is appreciated.
Hello Microsoft Community,
Anyone may tell me please what is Successful replication cycles?
What does it mean 22 out of 172 (12%)?
If its not 100% does it mean that the replica on the other server is not complete?
I have 2 Win 2016 Datacenter Server completely patched Server with same problems. When I restart the Hyper-V Host all VMs stay in Saved State and wait about 20 Minutes. Then the VMs are restoring and starting fine.
Hyper-V-Hypervisor Operational Log says:
about 8pm
Hyper-V successfully deleted a partition (partition 2).
about 8.23 pm (approx. 20 Min later)
Hyper-V successfully created a new partition (partition 2).
I have 8 VMs and with Total 12 VHD (IDE and SCSI mixed, Gen1 and Gen2) -> the event entries are exactly 12 times!
What I checked
************
-Powersaving on Host disabled
- a lot of free Discspace (45%)
- HP Proliant G9 with latest Firmware
- all Disks are DAS no Storagepool or SAN
- Test VM shutdown and stop and then restart Hosts - > not effect
- Hosts have DEP, Hyper-Threading and SLAT enabeld in BIOS
- Host NIC has Teaming (SR-IOV is disabeld)
I have an other Host with exact same Issue (similar Configuration).
Problem: it's annoying to wait always 20 Minutes after a restart till VMs are running.
thanks for any tipps.
Hi, I was trying to isntall linux subsystem through powershell, and when I tried to use "Enable-WindowsOptionalFeature -Online -FeatureName VirtualMachinePlatform" command, I get a following error,
Enable-WindowsOptionalFeature : Feature name VirtualMachinePlatform is unknown.
At line:1 char:1
+ Enable-WindowsOptionalFeature -Online -FeatureName VirtualMachinePlat ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [Enable-WindowsOptionalFeature], COMException
+ FullyQualifiedErrorId : Microsoft.Dism.Commands.EnableWindowsOptionalFeatureCommand
Not so sure how to fix this.
I first posted this on Microsoft Community, and one suggestion was to "Locate the Trusted Installer service, restart it, and set the startup type to automatic," but I wasn't able to locate that as well. How should I go about this issue?
Thanks
Hi guys,
Server OS: Windows Server 2012 R2
I have a VM Gen2 with following settings:
I can boot fine from the same .iso from a Gen1 VM so the .iso is bootable.
I know that the Gen2 VM uses SCSI instead of IDE, but I have no clue regarding how to boot from the .iso..
Any ideas?
Thanks in advance!
Best regards,
Kenny
Hi,
I have a Hyper-v host running several VMs ...
I would like to automate the Network configuration on 1 or several VMs via PowerShell.
When you use the cmdlet Get-VM, there is not the parameter -Name that I can use with the "Get-VM ... | New-NetIPAddress -IPAddress ..."
Do you have an idea please ?
Thank you.
Hi folks.
I've been trying to understand this for some days but it's still not clear to me. Read some articles about hyper-v memory handling but didn't help much on my case.
In a hyper-v Cluster with 4 nodes (Windows Server 2016 Datacenter) I have a VM (let's call it VM1, also with WS 2016 DC) that has 128GB static assigned memory. Note: It was created as Gen1 VM and the memory assigned is not exactly 128GB, but 128000MB (don't ask me why it was created that way, but i thought maybe the info could be relevant)
VM1's Memory Demand (in Hyper-V Manager) is about 111GB (86%) but the guest OS is using less than 50% (RAMMap below, from Guest OS)
Got an error updating the image here. See it here: https://ibb.co/WsH1JD6
I'm not worried about the host memory, since the majority of the VMs are static assigned. My question is because I was using the perf counter "Memory Pressure" to monitor my VM memory usage and see if any of them are close to start paging. But with this case (Memory Pressure is around 86) I'm starting to think that counter might not be the best way.
First and main question: Why memory demand and Guest OS memory usage are so different?
Second: Does it make sense to use Memory Pressure to monitor a VM with static assigned memory?
If I'm misunderstanding any concept here, it would be nice to know.
Thanks!

Recently went through a Microsoft RAP (Risk Assessment Program) and they flagged the following:
RECOMMENDATION:
Consider upgrading BIOS Versions that are between 5 and 7 years old.
DETAIL:
Server Name: _____ Release Date: 11/26/2012 12:00:00 AM Days Old: 2437 Manufacturer: [[GetValue Mfg.ReturnValue]] Serial Number: ____-_____-____-____-____-____-__ BIOS Version: Hyper-V UEFI Release v1.0 BIOS Major Version: 2 BIOS Minor Version: 4
So they are asking for my Hyper-V VM's BIOS/UEFI version to be upgraded.
I can understand how to update my physical devices, but I've never heard of updating this inside the VM.
Can anyone confirm this can be done and perhaps supply a helpful URL?
I have a hyper-v fail-over cluster with 4 nodes. All VM's and the hosts are on the same subnet and VLAN (601) so I've never had to worry about VLAN tagging. All 4 hosts are plugged into a layer 3 switch using trunk ports, so all VLAN's are available.
Each host has 2 physical NIC's, these are then teamed together (switch independent). Then a virtual switch (VSwitch-1) exists. 3 virtual network adapters then exist to this switch - Cluster, LiveMigration & Management.
I now have a new VM which needs to be in a particular VLAN for a door control system, this is VLAN11. The physical layer 3 switch appears to be configured ok, but I do not understated what I need to do in hyper-v and the VM itself.
Thanks in advance for suggestions, advice and help :)
Dear Microsoft!
On https://www.microsoft.com/en-us/evalcenter/evaluate-hyper-v-server-2019 you link the hyper v core server setup. However, it only leads to https://cloudblogs.microsoft.com/windowsserver/2018/11/13/update-on-windows-server-2019-availability/ and there is no download available.
When are you planning to make it available?
By the way: The download that was briefly online https://software-download.microsoft.com/download/pr/17763.1.180914-1434.rs5_release_SERVERHYPERCORE_OEM_X64FRE_EN-US.ISO is barely usable for 2 reasons:
A after installing it and activating Remote desktop, the server does not start to listen on port 3389. No RDP possible!
B Trying to do an in-place upgrade from Hyper-V Server 2016 leads to an error: "The installation failed in the SAFE_OS phase with an error during SET_Product_Key operation"
I am attempting to access a Hyper-V Management Console from a Windows 10 Pro Version 10.0.18362 Build 18362. The Hyper-V Server is running on a Window Server 2012R2. I am getting the following message when I attempt to access the Hyper-V Server from my Windows 10 Pro workstation.
The workstation and the Server are on the same domain and the Server is a domain controller. I have the domain user as a local user on the workstation and in the Hyper-V administrator group and the user is on the Server in the Hyper-V administrator group.
Looking at the Microsoft FAQ on Hyper-V the Windows 10 Pro Hyper-V MMC is backward compatable to Windows Server 2012R2.
Can anyone help with this issue or did Microsoft break this with the latest version of Windows 10 Pro.
Dear all,
I have a big problem with my hyper-v server and network card. I've found a lot of topic around this question but none of them helped me.
I have a Win 2008 R2 Server with only Hyper-V installed. I have 3 NIC , one is reserved to the host management and the others two are reserved for virtual machine .
All NIC are Intel, one is integrated on the Intel motherboard and the others are Intel Gigabit ET Dual port .
Before installing the role of Hyper-V all NIC worked perfectly with speed around 1Gb (file transfer average 90 MB/Sec, of course I have a Gigabit LAN) .
After Hyper-V install, the host system is going very slow and the network file transfer using the dedicated NIC is about ten time slower (9-10MB /sec) . Same problem with all VM off and also if I remove all VM !
I tried all of suggestion found in old post (disabling TCP checksum / offload ...) but nothing happens.
What is really strange is that by removing all network card all the Host operating system seems to improve the speed... but, of course, I can't use my LAN :(
I need help because every night I must make a full backup of Virtual hard disk from the host to a backup server in my lan.
My configuration:
- Server Win 2008 R2 SP1 with Hyper-V and no others role
- 2 Virtual Machine (one Win 2008 R2 and one Win 7 Ultimate)
- NAS Linux (access via SMB with no problem)
- Various Windows 7 Pro client
Thanks in advance to everybody,
Luca M.
