There are two functions in hvm.c to deal with tear-down and a domain: hvm_domain_relinquish_resources() and hvm_domain_destroy(). However, only the latter has an associated method in 'hvm_funcs'. This patch adds a method for the former and stub definitions for SVM and VMX. The VMX method will be used by a subsequent patch.
