Remove Hyper-V from Server 2019

I am setting up a MS Serer 2019 for Remote Desktop Services.  The Hyper-V feature was also install.  I am getting errors with RDS when trying to connect remotely.  From reading other MS Forums, multiple posts state that I need to remove the
Hyper-V feature to allow RDS to work correctly.  

I have tried to remove the Hyper-V feature using the Server Manger GUI as well as using PS as admin (Remove-WindowsFeature Hyper-V).  I have stopped all Hyper-V services before uninstalling, all fail.  During the reboot, the server will start removing
software and then fail, roll back and when I log in, Hyper-V is still installed.

Thank you in advance.

VM imported using Hyper-v getting restarted for every 30 minutes

Hi All,

I have a  windows 10 VM with enough memoy and cores(32 GB and 8 cores) in which i am trying import another cent OS VM using Hyper-V .  The VM brought up properly and without any issues. The problem is the imported VM(cent OS) is getting rebooted
automatically for every 30 min. 

I have verified the System Event logs and it shows the following but i am clueless what reason its getting restarted.

Could you please help me out it in solving this issue. I am getting this message when the VM restarts.

Virtual switch will limit host broadband upload bandwidth

Hi,

I am experiencing an issue that upload bandwidth, when I install a virtual switch in Hyper-V, to use my WiFi adapter.

When the switch is installed on my host system my upload bandwidth is approx. 1Mbit/s. When I remove the switch, the bandwidth is about 65Mbit/s

Download bandwidth is not affected.

I have been looking everywhere I can think of, to see if there is a setting with bandwidth limitation, but can’t find anything.

Anyone have an idea why this occurs?

Window Server Essential 2012R2 Latest update – Server can’t Hybernate/Sleep if Hyper-V is use

Hello,

I was wondering if this has been fix and how to do it?

PS C:windowssystem32> powercfg -h on
Hibernation failed with the following error: The request is not supported.

The following items are preventing hibernation on this system.
        An internal system component has disabled hibernation.
                Hypervisor

Microsoft article: https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2012-R2-and-2012/hh831410(v=ws.11)?redirectedfrom=MSDN

Sleep support

Sleep and hibernate are no longer disabled when the Hyper-V role is installed.

What value does this change add?

Computers running Hyper-V can be put into sleep or hibernate mode. This is particularly useful to users who are running Hyper-V on laptops computers.

Thank you

Virtual Switch configuration for nested Hyper-V in multi-NIC deployment.

I am a little confused about one thing, and it is to do with the configuration of the Virtual Switch(s) in a Hyper-V nested configuration (Server 2019) where there are a number of physical adapters (and virtual switches). I have looked at dozens of sources
such as these:

https://www.youtube.com/watch?v=ycCK1EyJG6Y&feature=youtu.be
https://techcommunity.microsoft.com/t5/virtualization/windows-insider-preview-nested-virtualization/ba-p/382256
https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/user-guide/nested-virtualization

In the picture there is a Server 2019 Hyper-V Physical Host (H0). It has two physical network cards. In the Hyper-V Virtual Switch Manager NIC1 becomes Virtual Switch (without quotes) "WAN" and NIC2 becomes Virtual Switch "LAN" and the
management operating system shares that. Both of these have the "External" Connection Type. WAN is connected to a Layer 3 router, then a firewall and the internet. LAN is connected to a Layer 2 physical switch on a specific VLAN that also has the
Domain Controllers, DHCP, DNS servers etc..

I now also create a new Virtual Switch with an "Internal Network" connection type. It appears in Network and Sharing Center as (no quotes) "vEthernet (VirtualSwitch1)". This virtual switch is ALSO shared with the management operating
system.

I now create a virtual machine in the Physical Host (H0) which is going to be a nested Hyper-V Virtual Host (H0.1). In my situation this machine will do two things.

  1. It will have its own virtual machine clients (C1.01, C1.02, etc.), and
  2. it will be the Routing and Remote Access Server for L2TP VPN authentication and access.

For the RRAS VPN machine H0.1 is configured in "Settings" to have Network Adapter WWW with MAC Spoofing set to off. The Network Adapter LAN is connected to the physical LAN for Active Directory, DHCP etc. and has MAC Spoofing set to off.

L2TP VPN works perfectly. Users accessing from the Internet are properly routed to H0.1 and correctly authenticated in Active Directory. No problems with the configuration or settings for Layer 2 and Layer 3 traffic.

My question is, what settings do I need to make to the Internal Network Adapter "vEthernet (VirtualSwitch1)" on:

  1. the Physical Host H0, and
  2. the Virtual Host H0.1

so that the clients C1.01, C1.02 etc can get DHCP leases from the Domain Controller attached to the physical LAN, and connect to the internet? Within the Settings for H0.1 this Network Adapter has MAC Address Spoofing set to ON. This virtual host also has
the Routing and Remote Access Role installed, but not NAT and not Direct Access.

I have been searching for days for an answer to this, and I just can’t seem to get MAC Address Spoofing or NAT Networking to work. Any advice would be helpful.

Windows 1909 – Hyper-V Quick Create Appcrash

I’ve upgraded this machine from Windows 10 Home to Windows 10 Pro, and enabled Hyper-V via the Windows Features GUI. Every time I select Hyper-V Quick Create, nothing happens and an event is logged to the Event Viewer.

The regular Hyper-V services apart from this appear to work correctly.

Have tried:

  • Rebooting the machine
  • Toggling the various Hyper-V services off and on
  • Running VMCreate.exe from Powershell and nothing is logged to the terminal

Delete checkpoint

After installing a windows update on Windows 2016 and restarting, the hyper-v host of  SQL server (mv) has a problem and hyper-v create a checkpoint. Now, SQL server uses 2.6tb, checkpoint uses 1.7tb, we have only 300 GB spaces
on Hyper-V VM disk. . 

1. Can we disable checkpoint? What will happen if we do?

2. If we try to delete the checkpoint, how many free spaces we need?

3. If we do not have enough spaces, what we may get if we try to delete checkpoint?

4. Any option do we have now?

Help, please!

How to properly configure network and MPIO for iSCSI in Hyper-V CSV storage scenario?

Alright, I have read a bunch of best practice guides on setting up storage and networks for a Hyper-V cluster. The issue is, hardly any of them explain
how to accomplish this, step by step.

I have one iSCSI target, with two Hyper-V host iSCSI initiators connecting to it. The iSCSI virtual disk has been set up as a CSV for Hyper-V storage. I understand that I need to have this iSCSI storage communication running on a dedicated network. I also
understand that I should enable/configure MPIO for iSCSI storage communication as well. I only have one physical NIC at this time to configure, and an external virtual switch created in Hyper-V. Currently, I have three networks recognized by my cluster, each
in their own subnet:

- ‘VDI-Switch’ - the name of the external virtual switch used for management communications and virtual machine access. Untagged.

- ‘Cluster’ network for heartbeat, etc. communications using vlan ID 11

- ‘Live Migration’ network using vlan ID 12

How do I make sure that iSCSI has it’s own dedicated storage communications network, and that MPIO is also enabled?

The best practice guides that I have read through are here, here, and here.
