Hi, It is a workable configuration. I'm not sure if there is much of a performance hit. With Solaris 10 10/08 (Update 6) you can of course build guest domains that use ZFS for the root file system.

For ZFS performance testing, make sure you are not running UFS on top of ZFS components" I was originally want to create a ZFS pool on service domain. All root file system of guest domains will be serviced from this poole. But from guest domain side, the root file system will created on UFS file system. Is this so called build UFS on top of ZFS? Is this bad implementation?
