OmniOS bhyve guest
I had a very pleasant surprise today. I have some work that I need to contribute to illumos and figured that a little dogfooding would be good for me. It seems as though two excellent distros for building illumos are OpenIndiana and OmniOS. Since I don’t really need a desktop and I’ve not used OmniOS before, OmniOS seemed like a great choice for the day.
After a bit of looking around at omniosce.org I came across something that was almost too good to be true: omnios-bhyve.zfs.xz!
Let’s take that for a spin:
# curl https://downloads.omniosce.org/media/bloody/omnios-bhyve.zfs.xz | xzcat | zfs recv zones/omnios

OMG! A few seconds later and I saw loader, and a few seconds after that I had a login prompt. Woot!
Well, let’s make this work with the SmartOS bits that are almost ready for you
to take for a spin. First, I’ll turn this into an image that will work well
with vmadm.
# zfs rename zones/omnios@good zones/omnios@final
# zfs send zones/omnios@final | pigz > /zones/images/6c4da93e-cffd-e809-a352-e4e11de3b067/disk0.zfs.gz

Next, shamelessly copy an early vmadm create payload to create a new vm.
# cp test.json omni1.json
# vi omni1.json
# vmadm create -f omni1.json
[some output that I lost in my haste. Just the normal stuff that says things went well.]
# vmadm console $(vm omni1)

Thanks much to (andyf?) for creating the image.
