Interestingly enough, there is /etc/init.d/before.local and after.local. You 
have to read /etc/init.d/rc to discover them. Basically, after.local runs 
after all the services have been started upon entering a runlevel. 
before.local runs before the runlevel is entered. If you anticipate changing 
runlevels often, you may want to restrict the actions in after.local to a 
particular runlevel.

In general, nope. But you can manually use 'xm vcpu-pin domid ...', and your  
domu will only use those vcpus till the next restart. (In my limited testing, 
linux reacts better to pinning than Windows.)

But you can restart the domus, so they can re-read their configs. You can do 
the vcpu pinning manually at first. Changing configs, and after.local, is 
just so it stays that way when you do reboot dom0/restart domu.
