   2 --------------------------
   3
   4 - flag indicating that cancellation of commands is supported
   5    - patches for cancellation of key creation exists
   6
   7 - improve on the logging
   8
   9 - QEMU-like monitor for initiation of migration;
  10   adds a capability flag
  11
  12    - only useful if migration error handling in QEMU can be properly
  13      supported so that fall-back to original host can work
  14      - either TPM or QEMU can cause the fall-back due to an error
  15    - needs to allow suspend/resume in QEMU
  16    - needs to prevent snapshotting in QEMU
  17
  18 swtpm_cert:
  19   - support for AIK Certs; takes EK and Platform certs as input:
  20     - copy data from EK Cert      : 3.5.9  .11
  21     - copy data from Platform Cert: 3.5.9, .11
  22   - needs implementation of some more TPM specific X.509 attributes that
  23     encode the data in ASN.1;
  24    - Unified cert specs 3.5.9, 3.5.11, 3.5.22, 3.5.23. 3.5.24, 3.5.25,
  25      3.5.26, 3.5.27
