similar to: Can't build 5.9 with KVM on a 6.3 host - DHCP hang?

I have a KVM setup. Host is 6.3. I have a bridged client running 5.9 Since upgrading to 5.9 I noticed that ntpd is being restarted every 12 hours. Jan 20 08:00:25 mercury ntpd[16103]: ntpd exiting on signal 15 Jan 20 20:00:26 mercury ntpd[27462]: ntpd exiting on signal 15 Jan 21 08:00:27 mercury ntpd[11343]: ntpd exiting on signal 15 Jan 21 20:00:28 mercury ntpd[25148]: ntpd exiting on signal

Summary: if you have C5 guests with dhclient "bad udp checksum" issues then this entry on the host will fix it: iptables -A POSTROUTING -t mangle -p udp --dport bootpc -j CHECKSUM --checksum-fill Detail: If anyone else is seeing this...

Hi, kickstarting fails due to problems with host resolution, even though the network seems to be properly configured through DHCP. eno1 and eno2 are both attached to the network, but only eno1 gets an IP via DHCP. Still `curl` cannot resolve the mirror host and the kickstart host during dracut-initqueue: rdsosreport.txt ------------------------------------------------ [...] [ 14.780428]

Hi. I have a machine with a local DHCP server and a couple of virtual networks and I've configured the server for each virtual interface, so that I would be able to install VMs on the corresponding subnets using PXE. The problem is that the two DHCP servers (my local server and dnsmasq) are conflicting with each other causing the boot process to either fails or takes ages untill a VM can

Hi, Ok it's better like this!:-) The dhcp failover mode works well and 2 windows 7 client PC are well handled. They can have an IP and addresses are created/deleted in the DNS successfully. but... I try to remove my 2 old windows 2000 AD server from the production's LAN and put my 2 new Samba4 instead. The dhcp servers works fine but not really the DDNS. We have this kind of error

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,

Hello. I recently tried installing NetBSD-5 on xen-4.0.1-rc5, which resulted in no network (xennet0 can''t get IPs per dhclient and has no connectivity if set by hand). Tried it with netBSD-5.1-RC3-1 i386 PAE & amd64, netBSD-5.0 and even 4, all with the same result. On a older xen version (3.3.1) networking works fine, so I assume it''s a xen bug, and not a netBSD-kernel
