Hyper-v

Hyper-v Converged network

Hi,

Im setting up a new 2016 failover cluster. I just want to clarify that im understanding the concept and design of this converged network. On my physical server i only have two 10Gb Nics which i need to team. The switchports in which the NICs are connected
as an etherchannel LACP and the etherchannel is an Access port.

So traditionally, i’d fire the LbfoAdmin console and configure NIC teaming on the management OS. In a Hyper-v Converged network, im not going to do this. Instead, Im going to team the NICs on the vSwitch itself. So id run a powershell that looks something
like this: New-VMSwitch -Name vSwitch -AllowManagementOS $True -NetAdapterName NIC1,NIC2 -EnableEmbeddedTeaming $True.
I will then configure vNICs and assign to appropriate vlan. When the packets from a VM with a vNiC configured for vlan 20 will leave the physical NIC and onto the switch, it will be tagged with vlan 20, likewise for ingress and Hyper-v will understand
where to deliver the packet. 

Is the above correct? I have two questions:

  1. In order for this work, i need to configure the switchport as a trunk port. However, would i need to remove the etherchannel LACP considering that EmbeddedTeaming is must likely not going to perform an LACP negotiation, or will it?
  2. Part of the traffic is obviously storage, ISCSI. I would like to configure MPIO between two NICs, or is it unnecessary because the EmbeddedTeaming takes care of aggregating and failing over? If not, then can i still configure MPIO?

Kerberos error when attempting to connect to Hyper-V Server from Hyper-V manager

When I am attempting to connect to the Hyper-V Server from the Hyper-V manager i get this error:

Hyper-V between Windows 10 & Windows 8.1 in a workgroup

I got my notebook and server connected to the switch which are not having internet. I configured the IP-addresses and subnets and they can ping to each other.
I can also start a remote session on the server from my notebook. They both are also in the same workgroup.

I already configured the Windows Hyper-V 2016 Server as TrustedHost on my notebook and TrustedHost on the server of my notebook also both with
CredSSP. I followed this video: https://www.youtube.com/watch?v=ffsRoZxUFGI&t=952s

Anyone knows if I need to activate or code something more? I have read that there were new updates that caused this error. The ISO file of the server is an evaluation file which I downloaded today. My notebook is running Windows 10 Pro with the newest updates
and build 1803. It is a HP Probook notebook.

Don’t mind my English language, I am a Dutch student and I still need to learn some better English 🙂

Thanks in advance.

Hyper-V in Windows Server 2012 R2 Essentials – Newbie information gathering question

Hello:

I am new to virtualization in general.  I am trying to figure out what I can do to install management software that uses SQL Server 2017.  As you know, SQL Server does not like to be installed on a domain controller which is the Windows Server
2012 R2 Essentials operating system. Rather than buy another server just to run SQL Server 2017 and buy another operating system, I was wondering if its possible to install the Hyper-V role and use the Hyper-V to create a virtual machine just for SQL
Server 2017, the management software and the remote access into the management software thru an IIS website that has an SSL Certificate.  Would I be able to leave the existing operating system the way it is if I am able to use Hyper-V? I am interpreting
some web sites as saying I could have 2 copies of my operating system then. One being virtual.. then other websites I interpret it as it becomes 2 virtual machines.. one basic, one with all roles and features.  I am not sure what to do, if its possible
or if I should be looking another direction. Again, I am totally green to this whole area so need some direction.  I don’t want to affect what the server is doing right now.. I don’t want to cause it issues by installing SQL Server 2017 on it.. possibly…

if this is possible at all in hyper-v… could someone point me in the right direction to learn more as a newbie and figure out how to configure it and access it etc…

auto revert to a snapshot after each vm reboot

Hi,

I like to config a VM will be revert to specific snapshot every reboot. Seen like Hyper-v not support that, so do we have any tool or script support that?

Thanks.

Cannot delete Checkpoint after manually merging avhdx-files

Hello!

we had a problem with our backup-software. There have been created checkpoints every day but haven’t deleted after the backup.
I merged the avhdx files until only a vhdx-disk has been left with the following powershell command:

merge-vhd -Path FS1_F6BECDB6-FE79-4A43-A550-7F5FD563A062.avhdx -DestinationPath FS1_FFA1D4D5-033F-4E3C-ACB4-222CBFBCE14D.avhdx

This works all find. Then I chanced the disks at the fail-over-manager from the avhdx-files to the vhdx.files. The server now runs without any problems.

BUT!! in the Hyper-V-manager the old checkpoint are still visble and I’m not able to delete them with the following message:
The operation failed because the file was not found.
That message is write - all the avhdx-files have been deleted.

How do I manage to delete these old - no longer existing - checkpoints? As long as they exist the backup-software will not create new ones and we don’t have a backup 🙁

I hope someone can help me to solve this problem.

Thank you in advance

Michael

Hyper V with NIC Teaming

Hi

I have to create Hyper Failover cluster and i will host 22 VMs with multiple Vlans ( vlan 33 , vlan 34 , vlan 42 Vlan 22)

my question:

After i create teaming and Virtual switches and Vnics

what is the TCP /IP configuration for Vnic ( Management , Live Migration , Clusters , etc)  is it required to put Gateway or ip & subnet only ??

What is the configuration for NIC teaming card ? shall i put ip adreess for Tnic?

I will create Vswitch for each different Vlan , what is the configuration in the VM itself to stick its vlan on its traffic?

Thanks

iSCSI LUNs dropping from VM?

Hi

We have a 2-node cluster. The nodes are running 2016 DC but most of our VMs are 2008 R2. We have a weird issue with one of those VMs (which File Services on to be a file server). This server has DFS-R to an identical server in another site.

If I RDP into this server and just watch ‘Computer’ in Windows Explorer, the C: drive will appear to lose connection, and so will the E: drive. The C: drive is a LUN on our NetApp FAS2020 SAN and the E:, F: and G: drives are LUNs on our QNAP iSCSI SAN.

All iSCSI traffic has dedicated LAN adapters AND switches. This seems to be the only VM affected by this ‘outage’.

As you can see, the C: and E: drives lose both the bar and text capacities below the drive, and we get the progress bar in the address bar as if Windows is trying to resolve them (which it eventually does). Plus, when this happens some of our applications
on client machines sieze up (we have folder redirection to this file server).

Where can I even begin to look to diagnose this one?!

Thanks
