I've been meaning to try out migrating a running Xen machine running asterisk from one computer to another to see if there's any call interruption. My rudimentary ping/ssh tests have been successful, showing no interruption of service.
Can you migrating a running container from one computer to another with Solaris 10? I know it's supported in VMWare ESX($$$), and Xen. The feature I'm really looking foward to in Xen is something called lock-step execution -- a technique which allows you to have two or more machines running the same instructions and have one immediately step in for another if the other crashes or has an underlying hardware fault. Along with that comes replayability, so that you can go back in time and see what the machine was doing just before the failure. Sweet! Cheers, Simon P.
