Nested Virtualization in Hyper-V 2016

So, I’m trying to setup this lab so I can learn Hyper-V 2016. I’m stuck at nested virtualization. 

I think I have a BIG issue because I have an AMD CPU instead of an Intel using VT-x and EPT technology.

Is there a work around to this?

I’ve tried enabling hyper-v with powershell but I get an error message when I boot the VM up.

I’m tying to avoid buying a whole new system.

2016 Multi-homed guest on Sept. Patched 2016 host

It seems that one of the patches in the last month or two has caused an oddity with multi-homed VMs.

Historically, a guest (or any installation of Windows) *can* have two vNics with static addresses on the same subnet, with the same gateway and DNS (the wisdom of that is irrelevant).  However, after patching a host with the August/Sept patches, and
rebooting the guest, the 2nd adapter alphabetically, on a multi-homed guest, will no longer recognize the domain profile, nor have network access.  It will revert to Public with no internet access.

If I move the guest to an unpatched host (june or july patch level), then reboot the guest, both vNic take the domain profile as expected.

For example - this is the multi-homed guest on an unpatched host… how it has always worked.  Again, these vNics have static addresses on the same subnet, same gateway, same DNS (and yes… I know all of the bad things about this).

This is the same guest, moved to a patched host, then rebooted -

Completely repeatable process.  Again, I do not know which patch causes the issue with the host, but the effect of the bug only seems to effect the guest VM.

Is this an intentional change of behavior from Microsoft, or an actual bug?

Thanks

SQL Application slow response in VM

I have a single Server 2016 Std. box running Hyper V. There is a single VM with Windows 10 installed. I’ve installed our RMS application, which connects to an SQL database, on the host and the application starts with no delays. I installed the application
on the Windows 10 VM and it takes a good 30 seconds longer to start.  Searches and other queries to the database also are delayed within the application.  Are there any specifics I should be checking within the Virtual Switch or other Hyper V configurations
that would be causing the VM to run the application that much slower?

Does Hyper-V actively block connections between local client and server?

If I had hair I’d be pulling it out.  We have Windows 10 Pro workstations running proprietary software in Hyper-V on XP and Windows 7 VMs.

One workstation has an XP client on the same subnet that cannot open shared folders or even ping each other. Both are able to connect to other computers on the network and it is easy to remote into the VM on other workstations, but impossible on the local
host.

The SMB vs 1 is enabled on the Windows 10 machine.

The Windows 7 VM is on the same virtual network and has no problems.

The question is in the title: Does Hyper-V actively block connections between local client and server? If so, how do I enable/disable this "feature?"

Anybody?

Hyper-V Replication State Stuck on "Waiting for Initial Replication" after Shared Nothing Live Migration – BUG or Real?

We have VMs that are replicating to Azure Site Recovery without issue.

One of those VMs was migrated (from 2012R2 host) over to a new Windows Server 2016 Hyper-V host that had the latest ASR agent installed.

In Hyper-V Manager, Replication shows normal. There are no errors in the Replication Health.

Everything appears normal and good on the Azure side as well.

However, if we run the PowerShell cmdlet Get-VM, it shows the replication state as "Waiting for Initial Replication"

Is this a bug or a real issue?

MinDiffAreaFileSize question

Hi,

We have Windows 2012R2 Failover Cluster with iSCSI array as a storage.

After implementing the backup application that uses VSS, we started to notice errors 5120 for one volume (only during backup job):

Cluster Shared Volume ‘Volume1’ (‘Vol1’) has entered a paused state because of ‘(c0130021)’. All I/O will temporarily be queued until a path to the volume is reestablished.

Then, one guest machine has stopped for a while with error 1069:

Cluster resource ‘Virtual Machine Server1’ of type ‘Virtual Machine’ in clustered role ‘Server1’ failed.

Based on the failure policies for the resource and role, the cluster service may try to bring the resource online on this node or move the group to another node of the cluster and then restart it.  Check the resource and group state using Failover
Cluster Manager or the Get-ClusterResource Windows PowerShell cmdlet.

I implemented the hotfixes and updates in accordance with
THIS
knowledge base article.

But I’m not sure if I should create MinDiffAreaFileSize value in registry that this hotfix applies to?:

Purpose of Hyper-V Virtual PC

Why would someone use a Virtual PC.?

Is it because it would be safe for browsing the internet.

Can external source from the Internet infect the main host PC when browsing with the VPC.

If I contracted a virus on the Virtual PC or something gets loaded without my permission.

Can Virtual PC be dissolved and recreated to start anew.

Would this be a solution for my Grandson who hoses up my PC with Virus from browsing and playing games.
