[libvirt-users] What to configure for a guest with 2.2. kernel ...

Greetings, libvirt-users ... I ask for help with virtualizing an ancient machine with a linux kernel 2.2. I already succeeded doing that but I face random performance issues and I somehow get lost in all the settings and options. I am using Virtual Machine Manager: * I can't chose something like Linux for the OS and 2.2 for the kernel. Does the combination "linux/2.4 kernel" work or should I choose "Other" or "Generic" ? * Later there I get a choice of "Architektur" (or "architecture" ? german here): for a 32bit-guest, should it be "i686" to reflect the environment for the guest or "x86_64" to fully use the potential of the host? Please forgive my questions, maybe they are FAQ somewhere, I really fiddled a lot already ... Thanks, Stefan
