We used to use HAL for two things: enumerating network devices, and enumerating block devices. The latter is provided by nodedev APIs which your libvirt supports. The former is provided by interface APIs which your libvirt does _not_ support, so virt-manager tries to fall back to HAL and fails. This failure shouldn't be fatal, just a small loss of functionality (specifically, host network devices will not be enumerated in the UI for creating VM network devices). In order for libvirt to provide those APIs, and arch linux backend would need to be provided for netcf. - Cole
