BlackCatTB

So I have a Problem: my two PCIe slots on my Server are taken by a GTX 1080ti and an 750ti and I want to run two VMs now my Problem is that unRAID uses my 750ti as output for the unRAID Terminal or GUI and as soon as I want to start the Second VM the terminal or GUI dissapers and I get no signal ;( I know that you might need an third card for unRAID in the first slot but I need both of the Cards and the onboard Graphics don't send output unless no GPU is inserted. Please Help! My Setup: HP ProLiant DL180 g6 with dual Intel Xeon X5650 CPUs and a 1080ti+750ti 16 Gb Ram 1 TB HDD as Parity + 500 GB HDD as Disk1
