Note, in addition to setting mem_stats_period_seconds = 0 in nova.conf, for currently running guests you will also need to manually remove the stats from the vms with something like virsh dommemstat $domname --period 0 --live

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
