Hello, every gentooers! |
| 5 |
|
| 6 |
I am running Gentoo with the latest Virt-Manager/Libvirtd/KVM windows |
| 7 |
2003 as Guest OS. Because the Broadcom of under the host environment |
| 8 |
works terrible of the performance and stability, so I want to pass it to |
| 9 |
my Guest windows 2003 OS. |
| 10 |
|
| 11 |
I followed the [tips](https://wiki.gentoo.org/wiki/QEMU/Options), and |
| 12 |
added my PIC wireless NIC through virt-manager, but when I boot, |
| 13 |
virt-manager complains as: |
| 14 |
|
| 15 |
bvirtError: unsupported configuration ：host doesn't support passthrough |
| 16 |
of host PCI devices |
| 17 |
|
| 18 |
Does anyone has this experience? |
| 19 |
Here some of my info: |
