If you are planning to use Solaris zones inside a LDOM and using an external zpool as Solaris zone disk, wouldn't this break one of the requirements for being able to do a Live Migration ? If so, do you have any ideas on how to use Solaris zones inside an LDOM and at the same time be able to do a Live Migration or is it impossible ? I know this may sound as a bad idea but I would very much like to know if it is doable.
By external pool I am thinking of the way you probably are doing it, separate LUNs mirrored in a zpool for the zones coming from two separate IO/Service domains. So even if this zpool exist inside the LDOM as zone storage this will not prevent LM ? That's good news. The requirement "no zpool if Live Migration" must then only be valid for the LDOM storage itself and not for storage attached to the running LDOM. I am also worried about a possible performance penalty introducing an extra layer of virtualisation. Have you done any tests regarding this ?
