K1和Vmware视图问题：设备8：0.0已在使用中

我有一台带有K1板的戴尔R720，我正在Vmware View 6中测试vDGA。
我的K1只会给我两个选项中的一个，或者将所有GPU分配给PCIe passthrough或者不分配。
不确定这是不是这样。
但是我的问题在于，当我将PCIe直通视频卡分配给VM时，第一个将启动正常，并且所有后续VM将拒绝启动并显示错误：设备8：0.0已在使用中。
VM 1分配为7：0.0
VM2分配为8：0.0
我尝试将vm2移动到9：0.0和A：0.0，结果相同，在任何给定时间只能运行1 vm。
有没有其他人有这个问题，并能够阐明它？



以下为原文

I have a Dell R720 with a K1 board in it that I am testing out vDGA in Vmware View 6.

My K1 will only give me one of 2 options, either assign all GPUs to PCIe passthrough or none.  Not sure if that is the way it is or not.

However my problem lies in that when I assign the PCIe passthrough video cards to a VM, the first one will boot fine, and all subsequent VMs will refuse to start and display the error:  Device 8:0.0 is already in use.  

VM 1 is assigned to 7:0.0
VM2 is assigned to 8:0.0

I have tried moving vm2 to 9:0.0 and A:0.0 with the same results, only 1 vm can operate at any given time.

Has anyone else had this problem and able to shed some light on it?
