  ****************************************************************
  When runnning z/VM 6.4 on an IBM z14 processor with one or more
  4768 Crypto Express6 cards, the crypto resources may not be
  assigned for shared use during z/VM system IPL and cannot be
  used for sharing once the system is up and running. This problem
  may also occur when running on an IBM z15 processor and Crypto
  Express6 cards are installed with no Crypto Express7 cards. The
  QUERY CRYPTO command response shows each of the configured
  Crypto Express6 coprocessors and accelerators as available,
  free, and unspecified. This happens after applying APAR
  VM66248, new function support for the IBM 4769 Crypto Card
  CEX7S, when the CRYPTO APVIRTUAL statement in the SYSTEM
  CONFIGURATION file is not used to specify the AP and domain
  numbers of the Crypto Express6 resources which are intended to
  be used for sharing.
  

Problem conclusion

• HCPKAP is changed to ensure that Crypto Express6 resources are
  found during z/VM system IPL when they haven't been specified
  on the CRYPTO APVIRTUAL statement in the SYSTEM CONFIGURATION
  file. The z/VM system will then operate as it did prior to this
  problem. If no CRYPTO APVIRTUAL statement is specified in the
  SYSTEM CONFIGURATION file, CP will choose the best crypto
  resources to be included in the shared pool. If the CRYPTO
  APVIRTUAL statement is specified in the SYSTEM CONFIGURATION
  file, CP will attempt to add the specified crypto resources to
  the shared pool.
