Exporting Solaris zone configurations

This article was posted by Matty on 2005-11-09 21:36:00 -0400 -0400

I have been using Solaris 10 zone technology for the past 4 - 5 months, and just recently came across the zonecfg(am) “export” option. This option allows you to export the configuration from a specific zone, which can be used to recreate zones, or as a template when adding additional zones (with some adjustments of course). The following example prints the zone configuration for a domain called “irc”:

$ zonecfg -z irc export

create -b
set zonepath=/export/home/zone_irc
set autoboot=false
add net
set address=192.168.1.4
set physical=hme0
end

This is super useful, and can make creating 1000s of zones a snap!

While surfing for material on virtualization, I came across the following Dell Xen whitepaper. The article provides an introduction to server virtualization concepts, and is a good read if you are looking for an introduction to virtualization and Xen.

Modern day pirates

If you thought pirates were a thing of the past, think again. This article describes an attack from several Somalian boats on a cruise liner. The article mentions that the captain invoked the “emergency response system,” which leads me to wonder if the captain used this response system as a reference when trying to run the attackers boats over? I would have enjoyed being part of those policy meetings. :)

Writing PCI device drivers

While researching PCI and MOESI this week, I came across the Sun developer connection article Writing Solaris PCI Device Drivers for Sun SPARC Platforms. While I am only 25% done reading it, the material is top notch, and is helping me understand the counters printed by busstat(1m).
