Deprecated Feature max-ipc in OVM3
I've been doing a little reading on upgrading from OVM2.2 to OVM3.x on SPARC and came across this section in the release notes. It says that the max-ipc option of the threading property has been deprecated.

I havent been able to find a simple answer to what this really means so I decided to post this question
A little background: Our system has a Solaris 10 guest which uses this property to control the count of virtual CPUs whilst still maintaining whole-core efficiency. The guest is running a Sybase ASE database which, in it's current version and licensing form, allows for 4 CPUs. Leaving the property as max-throughput whilst offering 4 whole-cores would therefore offer 32 vCPUs on our T4-2 which breaks the licensing (offering threads is obviously less efficient and underutilises resources if I understand correctly). max-ipc therefore presents 4 vCPUs as 4 whole-cores and everybody is happy.
