Re: [OmniOS-discuss] LX zones and a small Howto

[Guenther Alka]

I have added a menu in napp-it to select, download and preconfigure LX images 
from Joyent
beside the menu to configure/ attach/ start/ stop/ detach/ delete

http://www.napp-it.org/doc/downloads/zones.pdf

Whats not yet clear to me is the way to configure lx zones with 
zoneadm/zonecfg according to the settings in the Joyent XML file like 
network ip/dhcp, router, netmask, gateway, maxram, ssh, mount zfs 
filesystems to name a few.


btw
what about kvm branded zones from Joyent?
the concept is very new to me

What I must say is, that this seems to be a real killer innovation for OmniOS 
as you can run OmniOS as a very solid ZFS filer with additional Linux services 
running directly especially with preconfigured services as a container where 
you only need a copy and import/run after some small editings of a config file 
like shares or nics.

Joyent did most of the hard work here with LX -- credit where due, please. :)

By integrating it into OmniOS, though, you get the improvment of a 
fully-working global zone (where many sharing services can only function... 
e.g. no NFS in an NGZ currently) with the capability for closer-to-native Linux 
services (not as much running KVM in a zone now, for example).

Thanks for the napp-it update!

We didn't port all of SmartOS, we ported the LX zones.

For now, there are a few specific zonecfg(1M) parameters for kernel-version and 
network setting.  We hope to have /native/sbin/ipadm persistence before r151020 
ships.  Otherwise, you treat an LX zone like you would any other, using 
zonecfg(1M) where appropriate.

A KVM zone instantiates a zone, but instead of running a child init(1M) 
process, it runs KVM directly.  It wraps a KVM process in it's own zone, whose 
sole purpose is to service KVM.  We don't have these in OmniOS.  Like I said, 
we weren't porting all of SmartOS.

I'm trying to get r151020 out the door, so I can't for the time being.
