Its kind of funny how the windows server 2016 trial being installed on a hyper-v forces itself to find the wifi connection which is disabled and cannot be changed and I think i know why that is. last time i purchased the windows server 2012 r2 essentials 
it was at best a bogus experience.  I now realized that one cannot win against this kind of odds and its a lost cause.  I will never buy a windows server again.

Windows HyperV checkpoint behavior difference between 2016 and 2012R2 with storage failure

I am using Windows 2016 HyperV with HA file share exposed from Windows 2012R2. I observed that checkpoint creation succeed for HyperV 2012R2 with storage
fail-over, but fails for Windows 2016. After analysis found, 2012R2 do persistent open for all his VM memory, storage and config file. But, Win 2016 do it for storage disk only. Why such difference is here?

How to setup SMB Network drive connection on HyperV Server?

I’m used to work with VMWare ESX before, I have some basic knowledge of HyperV.

Except this one:

I want to mount my network location NASOperatingSystems to my HyperV server, so I can access my iso files fast and quickly when installing new machine on my HyperV test and education lab.

I known you can do this via gpo network drive connections but than a user needs to login.  When you boot up HyperV there is no user logged in so?

Thanks!

Cross Post: Experiencing Rendering Problem in Hyper-V Instance

Not seeing any luck in where I originally posted nearly 3 weeks ago, so spreading the love (more like pain 😆).  Check it out:

Hyper-V Replica Error 32022 recurring every 2 hours exactly during initial replication

Hello,

I have a problem with the initial Hyper-V replication of one of my VMs and I’m out of ideas. I will realy appreciate some help. The replication health goes critical with event ID 32022. Then replication resumes after one minute and exactly after two hours
(+/- 2-3 minutes) the error repeats. At exaclty the same time Event ID 29296 is logged on the replica server.  Both my Hyper-V host servers (primary and replica) are Windows 2016 Datacenter.

Currently both my servers are located next to each other (over a switch). 

I’m trying to replicate 4,2 TB distibuted into 4 virtual disks and it takes a lot fo time, However the same issue occurs even when trying to replicate with the VM turned off (so no changes to its virtual disks).

So every two hours, I have in the log the following:

Event ID32022 has either this description:

The description for Event ID 32022 from source Microsoft-Windows-Hyper-V-VMMS cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on
the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event: 

[My VM name]
1386FE00-0F0F-4931-9FB3-6C71993F335B
%%2147952454
0x80072746

The locale specific resource for the desired message is not present

,or this description:

Hyper-V could not replicate changes for virtual machine ‘[My VM name]’: The operation timed out (0x00002EE2). (Virtual machine ID 1386FE00-0F0F-4931-9FB3-6C71993F335B)

This event is immediately followed by:

Event ID 32315

Hyper-V failed to replicate changes for virtual machine ‘[My Vm]’ (Virtual machine ID 1386FE00-0F0F-4931-9FB3-6C71993F335B). Hyper-V will retry replication after 1 minute(s).

At the same time the following event occurs on the replica server:

The description for Event ID 29296 from source Microsoft-Windows-Hyper-V-VMMS cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the
local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event: 

[My VM name]
1386FE00-0F0F-4931-9FB3-6C71993F335B
%%2147942459
0x8007003B

The locale specific resource for the desired message is not present

Thanks for your help in advance!

Hyper-V Manager in Windows 2019 and Windows 10 1809 – ‘turn off VM’ no confirmation?

I know Server 2019 has been pulled, but I downloaded the ISO from VLK before it was pulled so we are still testing it. It was pulled because of the Windows 10 document issues, which has not anything to do with this issue.

In Hyper-V Manager, when I ‘turn off’ a VM, in both Windows 10 1809 and Server 2019 (with GUI) Hyper-V manager, there is no confirmation question anymore, which is potentially dangerous. The setting whether or not a confirmation should be asked used to be
stored in "%appdata%MicrosoftWindowsHyper-VClient1.0user.config";

       
            -1
       

However that setting doesn’t make any change anymore. Can anyone else confirm this before I create a ticket about that? Or might anyone know if there’s a simple fix?

Add-VMNetworkAdapterExtendedAcl and IPv6 subnet in RemoteIPAddress

I see a strange behavior with Add-VMNetworkAdapterExtendedAcl and IPv6. When a rule with a IPv6 subnet in the RemoteIPAddress is used, other matching allow rules are ignored.
Windows Server 1809 17763.55

Demonstration

$VMName = "my.vm.local" 
$SwitchName = "External" 
$ExternalIP4 = "1.1.1.1/30" 
$ExternalIP6 = "2:3:4:5::/64" 

VMNetworkAdapter = Get-VMNetworkAdapter -VMName $VMName | Where-Object -Property SwitchName -EQ $SwitchName

# remove all acls from VM
Get-VMNetworkAdapterExtendedAcl -VMName $VMName | Remove-VMNetworkAdapterExtendedAcl

# Allow SMTP 25 (later referred as Rule 1)
Add-VMNetworkAdapterExtendedAcl -VMNetworkAdapter $VMNetworkAdapter -Action "Allow" -Direction "Inbound" -LocalPort 25 -Protocol "TCP"
-Weight 10 -Stateful $True

# Traffic between VMs with external IPv6 (Rule 2)
Add-VMNetworkAdapterExtendedAcl -VMNetworkAdapter $VMNetworkAdapter -Action "Allow" -Direction "Inbound" -RemoteIPAddress $ExternalIP6
-Weight 11

# Block all incoming
Add-VMNetworkAdapterExtendedAcl -VMNetworkAdapter $VMNetworkAdapter -Action "Deny" -Direction "Inbound" -Weight 1

What I’m expecting is that telnet 2:3:4:5::4 25 works. However this is not the case.

Now if I exchange the weight of rule 1 and 2, it works as expected:
# Allow SMTP 25 (later referred as Rule 1)
Add-VMNetworkAdapterExtendedAcl -VMNetworkAdapter $VMNetworkAdapter -Action "Allow" -Direction "Inbound" -LocalPort 25 -Protocol "TCP"
-Weight 11 -Stateful $True

# Traffic between VMs with external IPv6 (Rule 2)
Add-VMNetworkAdapterExtendedAcl -VMNetworkAdapter $VMNetworkAdapter -Action "Allow" -Direction "Inbound" -RemoteIPAddress $ExternalIP6
-Weight 10

What is interesting, is that it works correctly when using a IPv4 subnet:

# Allow SMTP 25 (later referred as Rule 1)
Add-VMNetworkAdapterExtendedAcl -VMNetworkAdapter $VMNetworkAdapter -Action "Allow" -Direction "Inbound" -LocalPort 25 -Protocol "TCP"
-Weight 10 -Stateful $True

# Traffic between VMs with external IPv6 (Rule 2)
Add-VMNetworkAdapterExtendedAcl -VMNetworkAdapter $VMNetworkAdapter -Action "Allow" -Direction "Inbound" -RemoteIPAddress $ExternalIP4
-Weight 11
