Hi.I'm joining this subject, because this is one of several stoppers of migration from xen.
So, this is another init.d script to autostart libvirt domains. It also relays on libvirt autosave feature turned off. It's able to save running domains and resume them at startup. It has a feature not present in other scripts, it has autostart list of domain which should be started at boot if they have not been saved or could not be restored.
There is a problem (probably a bug in libvirt in Debian Lenny) during boot that some domains could not be resumed at several first tries. Author of this script knows of this problem and there is support to retry of resume in the script. There were 3 retries initially, I set it to 10.
In my case I have 3 domains of 1Gb of RAM whose are restoring Ok all the times, and 2 domain of 2 Gb RAM which have problems restoring. Sometime they restore Ok, some times they are restoring during first 10 retries, sometimes they are unable to restore even at 10 retries. I think this is somehow relate to amount of memory of domain.
Also, I checked other two scripts posted here, there is still problem with restore, it it doesn't relates to scripts being used. I think it's libvirt related. I've tryed later version of libvirt/kvm from backport - there were no problem with resume, but there is a problem with save which takes forever to save domain, so I rolled back.
