Hyper-V 2016 DDA issue: a VM boot fails when a drive is connected to an opposite NUMA node

Brief description: the host is Windows Server 2016 Datacenter Build 14393 (UEFI) running Hyper-V role. SR-IOV and Intel VT are enabled. 4x Intel® Optane
™ SSD 900P 280GB PCIe NVMe 3.0 drives are connected to the host. To check DDA support, I execute 
the
PowerShell script
 that returns OK, DDA is supported. Ubuntu Server 16.04 (gen 2) VM is deployed. All required
packages
 were installed to the VM. Then, I’ve connected those 4x Optane SSDs to the Ubuntu Server VM via
DDA
. After that, additional settings -LowMemoryMappedIoSpace
1Gb -HighMemoryMappedIoSpace 4Gb
 were applied. So, VM has passthrough connected 4x NVMe drives. The reboot/shutdown/power-on the Ubuntu VM works
without a problem. Also, there are no issues with the connectivity between drives and VM.

The problem case: when the Windows Server host reboots, the boot of Ubuntu Server VM fails.

From what I found, I assume a NUMA node configuration is the problem. The VM’s boot fails because of NVMe SSDs that are connected to another NUMA. For the information, 2x SSD drives are connected to #0 NUMA node and another 2x SSDs have the connection to #1
NUMA one.

So VM’s boot runs on the #1 NUMA node and fails. The VM boots only when NVMe SSDs running on #0 NUMA are disconnected.

Can not import virtual machines.

Hi,

we are trying to import virtual machines in Hyper-V2012 R2 but it fails with an error Hyper-V did not find virtual machines to import from the location, the folder c:somethingsomething could not be found. You might not have permission to access it.

Folder structure -Root folder with the name of machine-> 2 folders (virtual hard disks and virtual machines) -> In virtual hard disks folder there is .vhd file and in Virtual machines folder  there is the XML file and also folder with the same
name as XML file in which it has BIN and VSV file. 

These machines were created on a host (hyper-v 2012 R2) which is destroyed because of some irreparable issues. So those machines are basically not exported from anywhere. 

Is it because of these machines were not exported from anywhere at first place(because ".exp" file is not available), if yes is there any way to import these machines?  (there are a lot of machines, so ruling our creating empty virtual machines
option) 

Thanks in Advance.
