Hello Everyone,
I'm trying to passthrough two PCIe GPU's (Radeon HD 7970's) to a Windows 7 VM. I've been successful in getting one of the Radeon HD 7970's to passthrough but the second one shows this issue in the Windows 7 Device Manager:
The Microsoft support site indicates I might have an I/O port conflict or the BIOS did not allocate sufficient resources (neither of which is really helpful). Here are my config settings for that particular VM:
And here is everything in the two video cards IOMMU grouping:
And my PCIe devices as they pertain to the IOMMU grouping:
Not really sure what I'm doing wrong but any help is always appreciated!
I'm trying to passthrough two PCIe GPU's (Radeon HD 7970's) to a Windows 7 VM. I've been successful in getting one of the Radeon HD 7970's to passthrough but the second one shows this issue in the Windows 7 Device Manager:
Code:
This device cannot find enough free resources that it can use. (Code 12)
If you want to use this device, you will need to disable one of the other devices on this system.
The Microsoft support site indicates I might have an I/O port conflict or the BIOS did not allocate sufficient resources (neither of which is really helpful). Here are my config settings for that particular VM:
Code:
bootdisk: sata0
