I am running Gentoo Linux on an AMD64 laptop, and I am having an extremely hard time setting up host networking on KVM. I alreay have KVM, libvirtd, virt-manager, the kernel modules required to get virtualization working, and I already rebuilt my kernel with new configuration options according to this guide here, and I still cannot seem to be able to get host networking running.
I am able to create a VM using virt-manager, but I am unable to choose a network interface to connect my VM to, on virt-manager's final dialog under Advanced options, all the options on the drop-down box are disabled except "No networking" and "Specify shared device name". I cannot use bridge networking because my internet exit is through a wi-fi NIC.
I still can't get networking on KVM running. I do not want to use Oracle VM VirtualBox because I had a lot of problems with it in the past. Did I miss something?
