[Xen-devel] Problem after destroying domain when xm is configured to use Xen-API

[Stefan Berger <stefanb@xxxxxxxxxx>]

Domain with ID '12' is destroyed. When
VM.get_all_records() is called, the XendDomainInfo object of that domain
seems to still be around. It fails when calling xc.sched_credit_domain_get(12).

Error: (3, 'No such process')

My fix for this problem is to reset the domid in cleanupDomain()
so later on it does not call xc.sched_credit_domain_get() in get_vcpus_params,
though I don't see that the same line was removed through some patch.
