I know there was already a post about it but it was unresolved. I had to live migrate a lot of VMs recently (and still have to migrate more) and noticed the relationship between long uptime and the live migration time, I have proxmox clusted 6.1-5 and I have xternal ceph cluster for external storage. I am talkking about 5-10min migration vs. 20-30 sec migration. I noticed the same VM migrating from node B to node A taking 5-10 min to migrate and after that without rebooting the VM moving it back from node A to node B taking 20-30 sec. It definitely does not have anything to do with RAM usage. I migrated VM with the same amout of RAM utlizing 80-90% of it but one with short and one with long uptime and the short uptime was always faster by a big margin.
I will be doing more migrations this week with MVs running for a long time moving them back and forth - is there anything I can check and colect the logs/data to figure out why this is happening ?
My workaround has been to reboot the VM before the migration which takes fraction of the time to migrate it if it rungs for a long time.
Thank you
