linux-defconfig_xen0_x86* does [1]not have CONFIG_SMP set, so unless
you've manually changed the linux config, you won't see more than one
cpu.

1.  % grep CONFIG_SMP buildconfigs/linux-defconfig_xen0_x86_*
buildconfigs/linux-defconfig_xen0_x86_32:# CONFIG_SMP is not set
buildconfigs/linux-defconfig_xen0_x86_64:# CONFIG_SMP is not set
