If you intend to run this VM on different hardware or distribute it in any
way (so you don't really know on what hardware it will run) your best bet is
to set a generic arch like i686 or lower, OR hope the VM is run on software
based emulation (slow) so you don't have to worry about what CPU is running
it.

From my experience with qemu, you'll have a lot of requirements too, like
bridging and kernel module for virtual interfaces (tun/tap).

Now, if this will run on your machine, with kqemu, you'll set march on your
guest  as your host is...
