Hello Simon: With regards to migrating a running container... you got me there! I have no clue :). From what I understand and what I have seen in practice, is the containers in Solaris are designed to have added benefits. The primary benefit being running a cluster of the same services on several containers, data being accessed from a common SAN, and lets say if for some reason a service (eg. java app) fails in one container... you have the rest of the containers continuing to provide the same service (redundancy).
Another benefit is lets say you have 100 IP address. Each IP address is assigned to each container. You have 100 users. You give ALL 100 users root access. One of the root users is curious and nukes his container... the other 99 root users are not affected. Now with regards to lets say actually migrating the 99 users from one Solaris 10 physical server to another.... I'll forward this question to SUN and lets see what the folks there have to say. But yes! VMWare ESX is $$$ VMWare $$$ ESX $$$ :) You know... Sangoma and Digium ought to develop drivers for Solaris x86. Heck give me Solaris x86 driver and I'll give you x64 driver! At one time SUN had a porting tool to port Linux drivers to Native Solaris x86 and I just can't seem to find the bloody documentation on this! I'm in the zone, where if anyone says "Asterisk"... I think "drivers for Solaris please" !!! I can't shake it out of my head & if Sangoma or Digium doesn't come up with the drivers for all their toys... well... well... maybe I'll just keep my thoughts to myself ;).
