similar to: problem with dnsmasq and dhclient

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,

Hi CentOS users, I have install CentOS 7 in VirtualBox, and want the guest CentOS using dynamic IP address (The network type is bridged). I find the guest CentOS can works OK when using ethernet cable, but can't get IP address via wireless network. I also posted this issue on stackoverflow

Hello, I would like to set a specify default gateway for my VMs. However I’m not succeeding Here after is the isolated lan, where I added the statement <route address='10.0.0.0' prefix='8' gateway='10.10.0.7’/> where my aim is to route to the 10.10.0.7 What should I do , to make it works ? Thanks <network> <name>prd-private-lan</name>

Hi everyone, I'me having trouble with a CentOS 7 guest running on a Hyper-V host. For some reason, the CentOS guest randomly drops its IP address. Running "systemctl restart NetworkManager" on the console will restore IP connectivity without a reboot. I think that DHCP is timing out, but I'm not sure what to do about it. Is there a way to tell NetworkManager to keep trying after

Hello, I’m trying to set a default gateway on an isolated lan (because one of my VM get access to an other lan). I’m trying to use the option <route > but this doesn’t affect the default route on my VMs. Here is the network xml <network> <name>prd-private-lan</name> <uuid>2222222222222222222222</uuid> <bridge name='virbr3' stp='off'

This problem still bites us. I've tried to play around with DHCP settings (rd.net.timeout.dhcp, rd.net.dhcp.retry) to no avail. I'm happy about /any/ hint.

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]

I am having trouble with recovery. Today due to electrical work I powered down my networks Router / DHCP server. My Centos 7 host machines lost their DHCP lease (they are actually static leases). Once I power my Router / DHCP server back up none of my virtual machine were accessible. It appears that when the DHCP lease was lost on the virt server the bridge of the KVM guest were all losts. A

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
