[OmniOS-discuss] Reversed All-In-One

[Paul Jochum]

Hi Michael:

     As to your 2nd qustion, about having good info on how to create a 
custom lx image, I have used the following for smartOS: 
https://github.com/joyent/centos-lx-brand-image-builder
     (I am not sure how closely OmniOS tracks the smartOS lx branded 
zones, but wanted to pass it along in case it helps).  There are more 
links (in case you don't want to use centos as the base at:
https://wiki.smartos.org/display/DOC/LX+Branded+Zones#LXBrandedZones-Creatingyourownzonedataset

I'd love to say there's no more need for things like ESX in an all in one setup, but, there's still windows and some random others that has their niche needs on a box.

That is, run OmniOS as root system and control storage natively and run all linux needs in zones. Then if, and a big if, we could run ESXi in an lx zone.. And IF that is even possible, another big if.. IF we can present a zone with a ZFS volume as a raw block device, ESXi could then use it's native VMFS format on said block device. If that were so, that would eliminate all traditional latencies and bottlenecks caused by the network stack be it iSCSI or NFS and provide all the benefits of ZFS such as checksums and compression inline to ESX.. Obviously it couldn't vmotion in a cluster since the storage would be local to that box, but, the thought is currently for an all in one setup and not a cluster!
