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

need help with ips

Hi i have a server with hyper v running a few vms with some game servers  my isp provide me with 5 static ips and i have access to more if needed

what i am wanting to do is assign the static ips to the vms  right now  my isp router dose not have a lan network so i have tp link router with dhcp and my server  is connected to that on 192.168.0.8  with a subnet on 255.255.255.0 and
default gate way of 192.168.0.1  my tp link router wan is 94.x.x.34 and my ips default gate way is is 94.x.x.33   with a subnet of 255.255.255.240 i still have 94.x.x.35-38 free that i would like to use 

i have tryed a few things but nothing works for me i have no idea what im doing tbh

EventID 106 vswitch error logged

Since applying Jan19 updates recently we have been having crashing issues with one of the nodes in 2016 H-V cluster

Available processor sets of the underlying physical NICs belonging to the LBFO team on switch Friendly Name: Internal 10GB Logic Switch are not configured correctly. Reason: The processor sets overlap when LBFO is configured with sum-queue mode

This seems to be related to overlapping CPU cores in the vswitch team although this error has only recently started after patching the servers recently.

COuld someone pls confirm if the correct action would be: (NIC1 and 2 are the team members of the ‘Internal 10GB Logic Switch’)

Set-NetAdapterRss -name NIC1 -BaseProcessorNumber 0 -MaxProcessorNumber 7

Set-NetAdapterRss -name NIC2 -BaseProcessorNumber 8 -MaxProcessorNumber 16

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.

Guest VM can not connect to the network

I’m setting up a migration test server.  I have a Dell R610 with 2016 STD installed and Hyper-V for the host.  The server is connected to and a member of my work domain. 
I’m using two nics on the host machine, one connecting to the network (static ip) and a second (also connected to the network) for the VMs.  I’ve created a virtual switch that uses the second nic.

I’ve created a Server 2016 STD VM.  I can not get it to connect to anything.  I’ve tried leaving the virtual nic to dynamic ips and I’ve tried to add static ips.  But nothing is working.  What am I missing?

Hyper-V can’t attach NAS-hosted VHD file: "Failed to add device…the user name or password is incorrect"

Consider the following scenario:

Customer stores secondary backups of their Hyper-V VMs in the Acronis cloud backup service, as a fallback in case the primary offsite backup system fails or the buildings burn down or something.  They want to perform test restores to validate this approach,
which essentially means downloading VHD files from Acronis’s service to a Synology NAS, creating new VMs on a hypervisor, and attaching the downloaded VHD files to them.  The files still live on the NAS, not the hypervisor, because the files are very
large and the hypervisor’s own SSD storage is very expensive.

The ‘portability’ of these VHD files has never been an issue; we’ve always been able to copy them between hypervisors and run them.  However, this is the first time we’re attempting to run a VM that has its VHD file on a NAS vs. direct-attached storage
on the hypervisor itself.  The NAS share hosting the VHD files is mapped as a network drive on the hypervisor, which runs Server 2016 Standard.

When I attempt to attach a VHD file that’s on the NAS to a new VM, I get the following error:

We’ve tried the following: 

-mounting a NAS-hosted VHD file using the hypervisor’s Disk Management snap-in, to verify that we can see data there (works fine)

-as mentioned by
this Brian Posey article
, granting "Everyone" full control of the file temporarily, just to see if we can attach it to a VM (same error). Before anyone yells at me about security, this hypervisor and NAS are on a separate air-gapped network, and
we undid the change immediately.

-using the icacls fix suggested in the same article (same error)

-copying one of the NAS-hosted VHDs to the hypervisor’s own direct-attached storage, and attaching it to a VM.  (works fine!)

Neither the NAS nor the hypervisor are joined to an AD domain, so we’re using passthrough authentication (same local admin account on both hypervisor and NAS).  Accessing the NAS’s share via the hypervisor, we have no issues browsing subfolders, creating
test .txt files, or changing permissions on test files, suggesting it’s not a permissions or authentication problem.

What should we be trying next?  Thanks for your help!

Hyper-V Networking

Hello,

     I am sure this question has been asked before, however I have been unable to get this issue fixed. First, let me describe what I am trying to do. I want to setup a home lab with 3 servers, one to be the AD/DC, another for SharePoint and
finally a SQL server. I have 3 server 2016 datacenter servers setup currently. No other software installed at this time. I wanted to get the network issues fixed before proceeding. Right now I have network access on all three servers using "obtain ….
automatically".

So far every attempt I have made to give what will be the AD/DC  server a static IP has failed. No network connectivity. 

I am more of a programmer and network connection issues are not my specialty. 

Any advice on setting up the Hyper-V network?

thank you

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 a 4-6 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!
