The backports indeed fixes major problems that I was having with kvm62 - however I am experiencing regular crashes and haven't been able to figure out why, til now. This didn't occured during my testing phase, and even now occur fairly rarely (one same VM would crash every month or so) - but becomes an issue as you get more vms. > Ubuntu 9.10 (Karmic) has qemu-kvm-0.11, which seems more stable than > kvm-84, in my experience.

I think it's more me who assumed I would have a more stable KVM if I sticked to LTS - KVM being relatively new, I might have been better off upgrading every 6 months.

Are you aware of any other production deployment using 8.04 experiencing issues?

Oh my KVM hosts don't do much more than KVM, so I'd be fine with any version of Ubuntu, really. Will probably move my dev vms to lucid alpha, and test for a few months - and migrate everything to there after release. From there I might do the 6 months upgrade. Just thought that if the bug I am having was known and fixed I might get a quick workaround which would have helped me wait :) Thanks for your reply -- Yann HAMON Systems Manager Oxford Archaeology: Exploring the Human Journey http://thehumanjourney.net ------ Files attached to this email may be in ISO 26300 format (OASIS Open Document Format).
