Actually there are a lot of those posts in the syslog. Is there a way to find out the source of those requests? Can't find it under /etc/pve/*

Assuming this log comes from the host, I'd say you have a VM spamming dhcp requests, quickly draining the pool of available addresses, thus generating these messages. You should be able to identify the VM with the MAC and then see what's wrong with the network config.

VM configuration is stores under /etc/pve - means I should find the configuration with grep & the given mac.

But there is no server with this mac-address I think.
