yes thx Corbin, I should try setting mem_stats_period_seconds = 0 in libvirt section of nova.conf and then restart nova-compute on all hosts. Then I can try the live-migration again and see if that prevents VMs from unexpected shutdowns. Hopefully this works, and maybe this goes away with 7.3 when it comes, and I can enable the setting again than. thx will -------------- next part -------------- An HTML attachment was scrubbed...
