Server 2016 nested virtualization second level OS limitation?
Setup would be this:
Level 0: Hypervisor.
Level 1: Host Server 2016 named "Host", and the first guest with Server 2016 named "Guest-Level-1" and "Set-VMProcessor -VMName Name-ExposeVirtualizationExtensions $true" activated for this level 1 guest.
Level 2: No which OS are supported as Level-2 virtual machines within "Guest-Level-1"? Is this limited to Server 2016 or Windows 10 (at least 1607) as well?
Aside from supported: Any experience whether those Level 2 guests can be Server 2012 (R2) or Windows 8 (.1) or even Windows 7?

2019 Hyper-V virtual switch error
I have a clean install on an HP ML350 G10 server of Windows 2019 standard now that it was re-released.
The HP SPP worked fine to get all drivers loaded since 2019 isn't supported yet for the intelligent provisioning process.
Server activated, all four network card work fine. No bangs in device manager, all devices have drivers loaded and are recognized.
I've added the Hyper-V role, that goes fine.
Then trying to add an adapter to the hyper-v switch, it fails. Ultimately the error is that it can't find a file. This is trying to get the adapter installed via the GUI. So I dropped to powershell, tried to create it there, same error.
Tried every network card, same error.
Removed Hyper-V role, re-added it, same error.
Removed Hyper-V role, then when I added it, tried to add the interface to the network switch during the GUI install of the Hyper-V role. It didn't give an error, but when the install was done and system rebooted, there was nothing for the hyper-v switch.
And trying manually via GUI or powershell still does the same thing.
I'm not allowing the management operating system to share the adapter, although I tried with letting that happen and the result is the same.
Some of the things I've seen for older OS's like 2012 and 2016 said to remove the "Hyper-v Extensible Virtual Switch" from the bindings on the cards first then try again, but that won't uninstall. I get an error 0x80071779
I've removed and reinstalled the drivers, and a few different versions of the drivers, including the ones it finds automatically when I just went to the network card properties and told it to find drivers to update as well as the current and previous versions
on HP's website for this adapter.
Anyone else see this? It always comes back to "Error applying virtual switch properties changes. Failed while adding virtual ethernet switch connections." The details show the GUID of the adapter, with the final text, "The system
cannot find the file specified." and an error code of 0x80070002
Another post mentioned they solved something similar on an earlier windows build by disabling internet connection sharing - that's already disabled.
Another post mentioned antivirus causing this in a previous Windows server build - but this is a clean windows install, no antivirus is installed here.
One of the joys of playing with a new server build right at release...
Just in case it WAS something that was corrupted from the original install, I nuked it, reinstalled clean from scratch, and the problem persists.
I wish I had another spare server I could test this with to see if it's a bug with Windows, or simply some incompatibility with HP. But since other people have had this issue since 2012, I'm guessing there's just something I will have to wait to get
updated with by MS or by HP.
I made the mistake of posting the question on spiceworks and got people "instructing" about everything EXCEPT the actual problem. It's a bit like posting on an auto forum about a brake issue, and people "answer" complaining about the color of your car...
Since I have a business continuity device on this network I have no qualms about deploying 2019 this early for a Hyper-V role, as I can spin up any of its guests within minutes if something happens, so no complaining that "you shouldn't use 2019 in
production until after the first service pack," or other such. Let's please try to stick with the actual technical issue. I prefer to NOT have to deploy a 3+ year old OS on a brand new server now if I don't have to.
Thanks for any guesses...

Best way to reconfigure a 2016 failover cluster... Nodes and Cluster
Hi,
I have an operational cluster, but I need to rename the physical hypervisors and change the cluster name. I'v seen instructions on changing the cluster name, but what the best procedure seeing I need to rename the cluster nodes too? Thoughts?

Operation Failed
Hi,
I am trying to move a windows 7 VM from Win 2012 Std R2 to Win 2012 Std but it is showing Operation failed. Is it due to the dissimilar versions of windows 2012? How to move a VM in the scenario? Can I just copy the VHDs to the other server and create a new VM with it?
Thanks.

Drive performance with hyper-v cluster
I have a Dell VRTX which contains 4 server blades each running Server 2016 and internal shared storage which is made available via cluster shared volumes.
The server has a mix of drives as its been upgraded over time:-
4 x 600GB 10k SAS in RAID 10
5 x 600GB 10k SAS in RAID 5
9 x 900GB 10k SAS in RAID 5
4 x 1TB 7.2k SAS in RAID 5
I have run some disk performance tests using ATTO Disk Benchmark from within various VM's (Some Server 2012 R2 and some 2016). Some VM's are on different drive arrays (CSV's)
I am getting pretty consistent results from different VM's on the same arrays, so I'm comfortable the results are correct.
I still have some older Server 2012 R2 VM's which give averages of 900MB/s write and 1.7GB/s read on the RAID 10 array. These would have been Gen 1 original VM's.
I have one Server 2016 VM which was in-place upgraded from 2012 R2, still original IDE controller as first boot drive. This shows speeds of 1.1GB/s write and 2.46GB/s read.
I then created a brand new Server 2016 VM in the cluster, storing it's VHDX also on the RAID 10 array. This had SCSI as the boot drive type and gave averages of 3.2GB/s write and 3.33GB/s read.
I found these results interesting as it implied that server 2016 was faster on the same hardware, but also that the upgraded server was not as quick as a new one. Could this be as a result of fragmentation, deduplication, or the upgrade process?
So I then created some new small (only 20-30GB in size) VHDX files for both these VM's, creating one on each of the drive arrays to test with.
With the upgraded 2016 server I was now seeing speeds of 5.75GB/s write and the same for read. Similar speeds were encountered with the brand new Server 2016 VHDX's.
I also tried a new VM running Server 2019 and saw similar speeds (So some consistency here)
So it appears that my old Server 2012 R2 VM's and the upgraded 2016 VM are experiencing much slower disk throughput than either a new Server 2016 VM or a new VHDX assigned to them.
Any thoughts as to the reasons? Disk fragmentation over time, dedplication or something else?
My plan is to run the in place upgrade on the remaining Server 2012 R2 servers to make them 2016, however I would like to fix this performance problem as part of this, to ensure they are all running as fast as they can be.

Performance upgrade op SQL VM
Hi,
I did setup a new VM for SQL. Software vendor installed SQL2017 on it and their application. Clients are complaining about performance and speed of the application.
Is there a way i can approve the performance of the virtual machine or with other words the performance of the application. by adding more VCPU ? more Memory ? other settings ??
Any help would be welcome.
This is the Host i use :
HP DL380 G10 - 2 processors XeonSilver 4110 - RAM 144Gb - SAS disks 10K
RAID5 -> Host
RAID6 -> VM's
These are the VM settings for the (VM) SQL-server
1 Virtual CPU
32Gb RAM (not dynamic)
Disksize is 1Tb
Regards,
Jo

Virtual Switch
HI Team,
I have 2 nics in the server. NIC1 is for the HOST. NIC2 is setup as a virtual switch with management disabled.
Can I use this NIC2 virtual switch for multiple VMs on the server...?

HyperV Cluster Replica Broker error - "object could not be found" from Enable-VMReplication Powershell
Ok I admit it. This one is driving me crazy ;)
1) I have two Server2016 (Standard) HyperV Clusters - Source01 and DR01. Both part of same forest/domain.
2) Both Source01 and DR01 clusters have a HyperV Replica Broker installed and replication settings configured for Kerberos, Port80 and allow from any server.
3) I can initiate VM Replica successfully in both directions using the FailoverClusterManager UI. It creates the replica, transfers the initial data and everything appears to work.
However....
I need to create the replica using Powershell, but when I try to do it using the Enable-VMReplication powershell command it fails with:
I must be doing something wrong as the UI works. Perhaps some remote permissions not enabled? Remote WMI? something? hopefully some rookie mistake...
1) I've turned the firewall of DR01 off (just in case, just until figure out this issue)
2) The hyperV virtual machine management service is running correctly on both Source01 and DR01
3) the HyperV console on Source01 can correctly connect to DR01 and view/manage the VMs in the console - and vice versa.
Anyone got any ideas? Or seen this behaviour before?
thanks
Joe.

vhdx to vhds - what happens to deduplication & shadow copies?
I utilize Shadow Copies (for quick file restore) on dedicated volume & Dedup on 2012 R2 servers.
If I convert existing shared disks (vhdx to vhds) I assume all Shadow Copies will be gone.
And Dedup?
Thanks

Hyper-V Integrated Time Synchronization Service with NTP?
Hello there!
I've heard various debates on this but nothing current and no real good sources for reasoning. It would be good to find the current standing of this in 2019:
What is the ideal configuration of the Hyper-V Integrated Time Synchronization service in an environment where NTP is also used? For example, let's say there are 4-6 Linux VMs acting as NTP servers for other VMs on a network (please don't instead focus that it isn't a 'best practice' configuration -- that is off topic). Will the two time services interact with each other? Should Hyper-V Time Sync be disabled on the client VMs and/or the VMs running NTP services?
Thanks in advance!

Hyper-V in Workgroup - how to store VMs on network share?
Hello Gurus
I have 2 workstations both are in different workgroups...not DOMAIN. Long story but this is how it has to be.
I have Hyper-V running on 1 workstation - but I want to store the VM's on the other workstation... When I create the share and add everyone full control, it still does not work.. I know documentation says to add the computer object full permission but cannot do that in workgroup...
Can't use USB
Any creative workarounds for this?

VMs do not failback after Cluster Aware Updating was performed
Hi guys,
Recently it was noticed that after each of two-node failover cluster (based on Windows Server 2012 R2) was updated VMs didn't failback to their preferred node.
Question: is it behaviour of a failover cluster by design or it means that something doesn't work on a failover cluster in terms of failback feature?
Regards

HyperV 2012 Pfsense vlan support?
Hi guys.
I have a issue with a hyperV 2012 and pfsense 2.3.x which is working without issues.
Pfsense get 2 interfaces hn0(LAN), hn1(wan).
Now, we got a cisco switch core which manage all the vlans, we got routes inside pfsense and the lan gw is the switch core ip, if pfsense need to contact other vlan is use the switch core for that.
Now, I add a new vlan inside switch core and inside pfsense, we setup all, pfsense port is trunk, we add a client in a port mode access but I can see that pfsense driver hn0 won't support vlans, right?
What options we have to make our pfsense talk to a vlan?
Thanks all for your help.

After short time - VM was reset because an unrecoverable error occurred on a virtual processor that caused a triple fault.
Hello,
I had 3-node Hyper-V Cluster on Windows 2016 DTC. I decided to upgrade this cluster to Windows 2019 DTC version. I evicted first node from cluster, reinstalled to W2019 and added back to cluster. I tried live migration of some VM to this new node and everything
was ok. Then I reinstalled second node (same procedure), then I want to reinstall third node, I migrated VM from third 2016 node to the new nodes and I see that two VM are periodically unexpectly restarting and there is error in Hyper-V event log:
Hyper-V-Worker - EventID: 18560
'VMNAME' was reset because an unrecoverable error occurred on a virtual processor that caused a triple fault. If the problem persists, contact Product Support. (Virtual machine ID B2464510-3CCD-4A42-9776-2A61A3A5F40B)
Both virtual machines are Windows 2016 STD with latest updates. When I move this VMs to old Windows 2016 node, everything is working ok. When I move it back to new 2019 node, in a few minutes are restarting (VM starts, few minutes is working ok, then restart, start, few minutes ok, .............).
I found some bug solution for 18560 error - http://www.checkyourlogs.net/?p=59953 - but it's not my case because my VMs are booting ok.

How to emulate two graphic card
Hello,
I search a solution to emulate more one graphic card and screen in virtual machine. I need this for use with more 1 screen with specific remote acces software. To be clear,I want to use more 1 screen on vm with a software like Teamviewer.
I m searching solution with remote access service and RemoteFx functionnality on hyper-v. It's good way ?
Do you have another idea about this ?
Thanks !
