hi, i use IWStack from Prometeus. would like to known people experience with this service, and in general with Cloudstack, because i'm worried about recent issues i had.
would also like to have a reply from Salvatore, if possible, as their forum is currently "read-only" and the customer support replies are pretty "terse".
i've read of some recent issues on their forum, and had one myself on monday: i found a (production) instance (KVM) stopped for some reason, without any chance of restart it (stuck on "starting"). rebuilding from a disk snapshot may be the best solution here, but if i remember correctly i was not even able to start another instance on the same zone.
end of the story: i've rebuilt from scratch my server and all my apps on another zone (XEN), god bless IT automation tools. after ~8 hours i was still not able to start my old instance (and didn't received a single "yes we have a problem" reply). late reply was a bit scary: "no idea what the cause was".
anyone has similar problems? is cloudstack/iwstack actually suitable for production environments? maybe prometeus just need more experience with that? are XEN VMs better than KVM ones in this case? is there's some reason i should believe this will not happen again? using disk snapshots may be the best way to handle these situations?
thanks in advance.
