It works with maxcpus=1, and the other option is deprecated.

Also, I've edited /etc/xen/xend-config.sxp:

(dom0-cpus 1)

That seems to be the only thing to modify in the xen config file.

...about the documentation on the wiki, I think that list should be
updated or remade. Good time for it could be next document day!
