Virtual machines lose network connectivity

Using this article as a guide, we verified that the Hyper-V network team has VMQ enabled.  Resolution was to DISABLE VMQ on the Hyper-V team.  We did this on both Hyper-V hosts as they were setup identical.

Run the following powershell command (as administrator) to view the VMQ settings for all your adapters on the Hyper-V host. You will receive output similar to below.

> Get-NetAdapterVmq

Notice the highlighted network interfaces have VMQ enabled (TRUE). Run the following PowerShell command to get the network adapter’s VMQ names. You will receive output similar to below.

> Get-NetAdapterVmqQueue

Name                      QueueID MacAddress   VlanID Processor VmFriendlyName
—-                           ——- ———-        —— ——— ————–
HVLAN2                         0                                0:0                     HostServer01
HVLAN1                         0                                0:0                     HostServer01
Hyper-V Team              0                                0:0                     HostServer01

Once you have the VMQ names, run the following PowerShell commands as administrator to disable VMQ on each adapter.

> Set-NetAdapterVmq -Name “HVLAN1” -Enabled $False

> Set-NetAdapterVmq -Name “HVLAN2” -Enabled $False

> Set-NetAdapterVmq -Name “Hyper-V Team” -Enabled $False

Verify the VMQ settings on those interfaces by running the following PowerShell command as administrator.

> Get-NetAdapterVmq

All the interface should now read FALSE.
