Hm, executing an ESSA only makes CP think the guest understands CMMA, but the 
guest will not do it's part if it does not contain the required support. I 
would call that Uncooperative Memory Management Assist, UMMA for short ;-)

Subject: CMMA Support for Redhat



Hi,

I understand that RHEL5 provides support for basic CMM-1 (involving the z/VM 
VMRMSVM service).

Does anyone know if Redhat provides support for CMMA (also known at CMM-2, 
utilizing new hardware instructions)?  If so, what software/fixes/etc. are 
required?

Thanks,
Dennis Schaffer
