The normal way schedulers deal with this is to keep one list of all vcpus (= or all domains), and another list with "runnable" vcpus. =A0You c= an keep track of which vcpus are runnable with the vcpu_wake() callback and= by using vcpu_runnable() in schedule().

At very least, your loop in schedule should check vcpu_runnable() before se= lecting it.

Here's my random scheduler. It works until I start a virtual machine (e= rror file attached is the serial console's log).
In xen call trace there isn't any of my functions.
To generate random numbers I'm using the hash (MD5) of NOW() function.<= br> I would also Know why at boot time there are two calls at vcpu_init functio= n for vcpu with id =3D 0 ??

Thanks
