I have a proxmox-server running only ipv6 on a fixed IPv6-address (initial IP in the range). This host is setup with remote monitoring and have 100% uptime.
Then I have 40-50 vms that runs on IPv6 and I get "packet-loss" from Pingdom on these at certain fixed time. This packet loss is only for the vms and not for the proxmoxhost and last only less than a minute (from multiple locations).
How can I debug an issue like this?
The vms get's several ipv6-ips assigned after few days (more than the one it gets on first boot), with the previous being set as "depreciated dynamic", but still pingable. Option EUI64 is enabled in the GUI.
Attached is screenshot before and after the incident have happened. Note that I'm not sure if this is the cause of the ping-drop, but I do see these differences in the config appear automatically without me doing anything. It is strange that it adds ipv6-addresses.

On the vm itself, I can see this just before the error occour:
