Hi

 

I am trying to passthrough a 10 GbE network adapter to a Windows VM, but I have no luck. The motherboard is a supermicro C9X299-PG300F.

 

 

First I tried a ASUS XG-C100C adapter, but once inside windows it kept resetting itself all the time. Sometimes I could get it working, but then after reboot it was failed again. It just kept saying "unidentified network" and kept resetting. The event log talked about hardware failure.

 

Now I have changed out the adapter to a Supermicro Intel X550, and the failure is similar. I can sometimes get it working, but after a while windows disables the card due hardware failure. If I manually remove it in the device manager, I can get it working again, but it soon gets disabled again, and it does not last a reboot. I have tried different BIOS settings (per pcie slot) LEGACY, OFF and UEFI, and I have tried changing PCIE slot. Nothing seems to help. Now I am out of ideas...

 

Anyone got some idea?

 

Regards,

 

Jesper

I have the same problem as you, did you find a solution ?

I managed to make my card work for 2m but after one stay it no longer works

 

He first detected my card in ipv6 on my box so once detect I assigned him an ipv4 lease and he managed to connect correctly on windows.
