Mark,
Here's my doc on the subject...

Differences b/w running native LPAR and running as a z/VM guest
In a single system:
The only issue Im aware of is some strangeness with your performance monitors.
In a SYSPLEX:
--A new CFRM policy is required, specifying SIMDEV for the coupling facility:
CF NAME(CFCC1
TYPE(SIMDEV)
MFG(IBM)
PLANT(EN)
SEQUENCE(0000000CFCC1)
PARTITION(0)
CPCID(00)
DUMPSPACE(2000)
Type Number (TYPE) - SIMDEV specifies that this is a z/VM simulated message
device type.
Manufacturer (MFG) - IBM® indicates IBM as the manufacturer.
Plant (PLANT) - EN indicates Endicott as the manufacturing plant.
Sequence # (SEQUENCE) - The 12-byte field will contain the CF Service
Machine user ID right justified. Pad all leading unused characters with
EBCDIC zeros. For example, if a CF Service Machine of CFCC1 is specified,
SEQUENCE is 0000000CFCC1. Your DR provider may have a different CF name.
--A different CLOCKxx member may be needed specifying SIMETRID:
TIMEZONE W.04.00.00
ETRMODE YES
ETRDELTA 10
ETRZONE YES
SIMETRID 00
--Possible CFSizing needed:
If you are on a processor that has a lower level of CF Code, you may need to
resize your structures. For example, if your DR provider has a z10 (CFLEVEL 16)
and you are running on a z9 (CFLEVEL 15), you may need to increase the storage
size of the CF.
>It's been many, many years since we've run our sysplex under zVM. Our next DR
>exercise will be hosted in a VM >environment and I'm looking for any
>environmental setup concerns that I need to consider.
>I know that we'll have to change LOADxx, but I'm unsure about anything else.
>Any advice on what I have to do would be greatly appreciated.
