I had a Windows 7 Ultimate SP1 64-bit system that I captured an image of and imported into Proxmox. The Windows 7 system boots fine, but I do not have any networking on it. I have it assigned to vmbr0 like it is supposed to be, other VMs on this interface have network/internet access. However, on this Windows 7 system that I captured, when I go to Control Panel -> Device Manager, the Network adapter has the yellow exclamation mark, and checking its properties, it says "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 physical Windows 7 system uses a Realtek RTL8168D network adapter, and with the system captured and virtualized, I've tried the Proxmox e1000 and virtio network adapter and both give this same error. No other NICs are listed than the Proxmox one. Any ideas?
