Thank you.

The config looks OK for this Gen 1 VM, except the odd memory configuration.
Can you look up the Hyper-V logs on the host:
particularly hypervisor/operational and VMMS/admin?
You can use Powershell to collect the logs if you like.
Here's a sample script. After running the script to load the function you can run:
Get-HVEventLog -Computername MyHVHost-Days 7

Sam,
i corrected the memory settings & assigned static memory as 1024 MB.
there was two blocks of scripts in that website, i don't which of them i must run.
i verified my event viewer as i had done earlier, i the following are the only events which are are logged in all hyper-v related notes:
hyper-v-hyperVisor node:
Hyper-V successfully created a new partition (partition 3).
Hyper-v-synthnic node:
'test4' Network Adapter (7F8B9901-BBF5-4541-B586-33A5EE906B49) started successfully. (Virtual Machine ID D3589B09-C269-46CE-9BD1-51A3C95C04BF)
'test4' Network Adapter (d3589b09-c269-46ce-9bd1-51a3c95c04bf--7f8b9901-bbf5-4541-b586-33a5ee906b49) Disconnected from virtual network. (Virtual Machine ID D3589B09-C269-46CE-9BD1-51A3C95C04BF)
Hyper-v-worker node:
'test4' started successfully. (Virtual machine ID D3589B09-C269-46CE-9BD1-51A3C95C04BF)
and also in Custom node\ Administrative events, an error is logged continuously ---->
 Microsoft-Windows-Kernel-EventTracing/Admin :
Session "" failed to start with the following error: 0xC000000D (event ID 2)
