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 Here after is an extract from the log July 1st 2016, 05:08:46.156 zen.pipiche.net <http://zen.pipiche.net/> dnsmasq-dhcp DHCPREQUEST...

I''m running a nevada b99 guest on a nevada b99 host. The guest is configured as a dhcp client. When I snoop in dom0 while the guest boots, I see two back-to-back DHCPREQUEST packets issued by the guest. The first of the two packets has an empty UDP checksum; otherwise they seem identical. Is this a bug? Fred Oliver ETHER: ----- Ether Header ----- ETHER: ETHER: Packet 246 arrived at 16:27:44.20927 ETHER: Packet size = 342 bytes ETHER: Destination = ff:ff:ff:ff:...

...kage: logcheck-database Version: 1.2.23 Severity: minor Hi, a couple of minor corrections to the dhcp rule sets: First of all, the hostname matching parts need to include the "._-" signs (maybe . is not needed but it might be). Then when using failover, log lines of type DHCPDISCOVER and DHCPREQUEST may be entailed by the string ": load balance to peer <somestring>". I've also had the message ": wrong network." appended, when a client requested an ip adress out of a different domain, which will result in a DHCPNAK. This is a common case with WLAN users i think. I...
