2012 Recreate collection of VMs fails, Post-patch failed"

Windows 10 VMs - I created a new Win 10 2016 LTSB (1607) template from scratch, applied all updates, sysprepped - just like I would do with the previous template which was Win 10 ent 1804 (not LTSB). Anyway, when I execute "recreate all desktops in
pool" and point to the new template, it takes a long time, then eventually fails. The first VM’s status is Post-patch failed, all others are job canceled. I’m looking through the Hyper-V logs, but nothing jumps out at me. In fact, the only entry I see
is for the one that Post-patch failed.

I’ve confirmed that the VM did export as a template.

Log: Microsoft Windows Hyper-V15 Worker/Admin

Event ID: 18510

‘BASE-0’ saved successfully. (Virtual machine ID 741112D6-0B23-4521-8C8F-7ECA9E144843)

Any idea where I should look to see what’s happening?

Edit: I closed the wizard and then launched Task Status and now get a bit more information for the VM that Post-patch failed - "Failed: The virtual machine is not ready for the virtual machine-based desktop deployment."

My gut instinct is I can’t downgrade win 10 VMs from 1804 to 1607, time to find out what google thinks.

Edit 2: Setup a new resource pool, pointed it at my new template, same errors.
Edit 3: Hyper-V-VMMS/Admin, Event ID: 15090 ‘BASE-0’ failed to modify resources.

Edit 4: Hyper-V-VMMS/Storage Event IS 27002 (A whole lot of these) The description for Event ID 27002 from source Microsoft-Windows-Hyper-V-VMMS cannot be found.

Thin Client Network Communication Interruption

Does anyone help in finding the root cause of the below issue

"Memory allocated for packets in a vRss queue (on CPU 10) on switch C7F0382C-8091-4600-9793-2E49DC6C8B65 (Friendly Name: Thin Client Network Secondary) due to low resource on the physical NIC has increased to
67584MB. Packets will be dropped once queue size reaches 512MB."

The above messages started appearing for 15 minutes, finally the memory allocated increased to 72.9 GB and hosts rebooted by windows bugcheck utility. VMQ was enabled.

when these messages started appearing, the all thin client machines lost connectivity with the VRTX hosts. we have redundant VRTX and redundant thin client network. But non of the redundancy worked.

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.

Hyper-V Integration Services for Ubuntu 18.04 LTS servers


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).

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

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.

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.



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 to is not handled by the

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