Hello,
I have a problem which is that some of my VMs are loosing there IP addresses from time to
time. What I saw in the log is when this VM loose its IP address there are DHCPREQUEST
send from the VM by dhclient and the server responded only 50 minutes later !
Any help, advise on how to debug would be welcome.
Thanks in advance
Patrick
