New vm freezes server

[nt7561]

Hi everyone. 

I'm having a big problem with my unraid server. 

I'm trying to set up a windows 10 vm iot run blue iris application for my cameras. 

I have already set up 2 vms (homeassistant and windows 10) but with no gpu passthough and they run okay. I have also 4 docker containers with no issues. 

Every time I try to create and start the new vm with gpu pass-through (sapphire pulse rx 580 8gb) my unraid server freezes and I have to hard reboot it. 

How can I resolve this? 

My hardware is : supermicro x8dtl-3f mobo with dual xeon x5670, 24gb ram ecc, 16 tb array (with one parity disk) and 2 ssd's (one 240gb for docker and vms and one 120 gb as cache). 

Many thanks in advance for your reply. 

Regards Nick. 

P. S. I'm attaching a screenshot of my vm set (that freezes unraid)
