Moving HyperV guests to a hyperV Cluster?

we have several Hyper V servers, each with several guest machines.  The Hosts range from server 2008 R2 to 2012 and are domain members.

We set up a new cluster (3 2016 servers) and want to migrate the guests to the new cluster setup.

what is the best process for this, can anyone provide an article or post about this.

Fibre Channel MPIV with Live Migration on Hyper-V

Hi Folks,

I’ve 2 Hyper-V servers.

Each server has 1 Physical HBA card used for SAN presentation(dedicated for SAN for Guest VM).

I’ve a guest VM running server 2012.

Fibre Channel Adapter has been created on one of this host and zoning has been created with NPIV is enabled.

Both the 2 Hyper-V servers are in a clustered mode. When i try to migrate the guest VM from one host the migration fails.

How can i ensure that the live migration works seamlessly from one host to another in case of host failure. The VM is getting isolated to one specific host and not failing over. Any suggestions would be of great help.

Thanks

Hyper-V Integration Services for Ubuntu 18.04 LTS servers

Hello,

We have a Hyper-V Cluster with several VMs, which also includes Servers in Linux (Ubuntu mainly). Versions LTS are desired over the regular 6 months releases, and had (until today) no problem with them because of the integration services, offered by Microsoft
(IP Injection among others).

https://docs.microsoft.com/en-us/windows-server/virtualization/hyper-v/supported-ubuntu-virtual-machines-on-hyper-v

To deploy new VMs we use Templates. Unfortunately, when creating a new template for Ubuntu 18.04 LTS the VMM will not finish the creation of the new VM, because of the recent changes of Ubuntu 18 and its change from /etc/interfaces to netplan.io

https://wiki.ubuntu.com/BionicBeaver/ReleaseNotes#Ubuntu_Server

I am not sure if there is (like the other versions of Ubuntu) an update from Microsoft to integrate these VMs to a Hyper-V environment, or (if any) i would appreciate the help with any workaround to this issue.

I appreciate your help and guidance.

Best regards,

vEthernet (Default Switch) can’t disable

Does anyone know a way to permanently disable or change the settings of the Default Switch created when setting up a VM in Hyper V.  Host is Windows 10 1803, the VM is Windows 7, I’ve created an external switch but unless I disable
the Default Switch I can’t get internet access on the host machine or the VM but everytime I restart the machine the Default Switch is enabled again, not a bother for me but trying to explain that to users is a bit difficult.

Thanks

Configuring vLAN environment on multiple network on Hyper-V

We want to use four VLANs. Servers have been assigned no. 601, and areas 3, 4, and 5 will be assigned to clients with Windows 7.

I want clients in each of the 3, 4 and 5 VLAN areas to communicate with 601. Can you tell me how to configure in Hyper-v in detail with the Powershell command and each step in Step by Step?

The network administrator has already configured each VLAN on the physical switch. The Hyper-V host has four adapters. To achieve the above objectives, I would like to be able to tell Hyper-V hosts what configuration and environment to configure.

I’ve seen and followed various documents that make up the vLAN environment, but I think it’s a very difficult problem for me, so I’d like to ask you how to list them in the most detailed order.

Thanx

Plus,

Hyper-V Host have 6 NICs. Following the above question, is it appropriate to allocate a physical Ethernet port for each vLAN? In other words, one Hyper-V host IP, one for each VLAN and one for Trunk port configuration. If that is correct, should a total
of six physical NICs be required and IP be given for each NIC?

Blocking Traffic Within Network Using Hyper V

Hi Team,

My boss wants me to seperate two servers within a network from the rest of the network. He asked me to do so at the firewall level. As traffic within a network is a layer 2 issue, the traffic from 192.168.50.30 to 192.168.50.0(subnet) is not handled by the
firewall.

Is there a way to block traffic between 192.168.50.30 and 192.168.50.31 from the rest of the network 192.168.50.0 from Hyper V Switch, while also allowing traffic out to the web?

Get Schedule Task ACTUAL TASK!

I placed this in the Hyper-V section since I am running Hyperv 2012 R2 standalone server, so no GUI. I would of placed this in a powershell/cmd or CLI section had there been one.

I put in some schedule task, but I am finding it hard to SEE what the actual task is suppose to run. It blows my mind that this wasn’t something I could easily find with google or through the help menu.

I tried schtasks /query /tn NAMEOFTASK

but it only returns the Taskname, Next Run Time, and Status

How do I see what the actual task will do?!?!

also tried

Get-ScheduleTask TaskName | Get-ScheduledTaskInfo

Also just as useless. Am I crazy or does this information simply not obtainable through the command line, at least without a simple command and switch.  Any Insight or Windows BASHing is welcomed. Thanks in advance.

VMM2016 can’t build new VM

Hi,

I am running VMM 2016 and HyperV Core 2016 and it used to function fine when building new VMs, now it fails each time with the following error:

Error (20408)

VMM could not get the specified instance Scvmm_EthernetSwitchPortInternalSettingData.InstanceID="Microsoft:Definition1f59a509-a6ba-4aba-8504-b29d542d44bbDefault" of class Scvmm_EthernetSwitchPortInternalSettingData on the server xxx.xxx.xx.xxx.co.uk.
The operation failed with error HRESULT 0x80338000 The WS-Management service cannot process the request. The class Scvmm_EthernetSwitchPortInternalSettingData does not exist in the root/virtualization/v2 namespace.

However, if I use HyperV manager then I can build the VMs OK and VMM2016 will then allow control of most functions, my othe rHyper-V Core 2016 servers running under the same VMM2016 instance are working just
fine.

Can anyone shed some light on this please?
