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.

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 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

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

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]

Hi all. I recently turned net.inet.udp.log_in_vain on on some of my boxen and have been seeing UDP connection attempts to port 67 on the local host. This initially seemed odd, as the target ip addres was indeed that of a DHCP-configured interface and the source address was that of my DHCP server. However, it turns out this is totally valid, as dhclient(8) does not bind(2) on the bootpc port but

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

Hello, After asking around in #centos and other linux related IRC channels, here I am, bugging all of you. brace for the long post. (tldr: dhclient loses virtual interface ips) I set up a system to deploy statically assigned IPs to physical and virtual interfaces to a number of (virtual) machines. I have a DHCPD with an entry for each virtual ip in the form of host eth0-1.virt1.test.it {
