VM66627: PEVM66532 RMF WITH THE VMGUEST OPTION WILL FAIL

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• RMF used by z/OS running as a guest of z/VM with VM66532 will
  fail if the VMGUEST RMF option is in effect.
  In this environment, RMF will fail, and z/OS may take SVC dumps
  and ultimately return with a non-zero completion code with a
  return code reflecting the interruption encountered by RMF. The
  RMF failure is caused by an error in the way z/VM formats a
  diagnose x'204' response buffer. To avoid RMF failure, ensure
  the NOVMGUEST RMF option is in effect. If RMF is not running,
  ensure VMGUEST is not specified in any ERBRMFxx parmlib members
  for a Monitor I data gatherer session. By default, the
  NOVMGUEST option is used by RMF when the NOVMGUEST or VMGUEST
  options are not specified by any parmlib members. If RMF is
  running, the option can be queried using the 'F RMF,D ZZ'
  console command. If the VMGUEST option is present, the 'F
  RMF,F ZZ, NOVMGUEST' console command can be used to change the
  setting dynamically.
  

Local fix

• To avoid RMF failure, ensure the NOVMGUEST RMF option is in
  effect. If RMF is not running, ensure VMGUEST is not specified
  in any EBRMFxx parmlib members for a Monitor I data gatherer
  session. If RMF is running, the option can be queried using the
  'F RMF,D ZZ' console command. If the VMGUEST option is present,
  the 'F RMF,F ZZ,NOVMGUEST' console command can be used to change
  the setting dynamically.
