As a general rule (with a couple of exception) Fedora only ships kernel modules which are in upstream LKML sources. kqemu is not upstream, so it is not included in Fedora RPMs for QEMU. > 2) Does an activated QEMU acceleration layer (missing above) make a > huge difference? Yes, it improves performance signficantly - although not all OS will run under kqemu. > 3) I have several operating systems successfully loaded in Qemu > sessions, but networking is just not working.

If you setup your host network in appropriate manner they can also be bridged In this doc where you see 'kvm' - 'qemu' applies just the same way http://watzmann.net/blog/index.php/2007/04/27/networking_with_kvm_and_libvirt The main potential gotcha I know is that ip_forward must be enabled eg, $ /sbin/sysctl net.ipv4.ip_forward net.ipv4.ip_forward = 1 > 4) Finally is there a preferred distro which is known to solve all the > problems mentioned above? Networking should work correctly for NAT & bridging (assuming suitable host config). KQEMU won't work in Fedora since the module is not upstream.
